The Bank has prepared and filed with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the "Securities Act"), an "automatic shelf registration statement", as such term is defined under Rule 405 under the Securities Act, on Form F-3 (File No. 333-283007), including a prospectus, relating to the Securities and such registration statement became effective upon filing with the Commission on November 5, 2024, in accordance with Rule 462(e) under the Securities Act, as amended as of the Effective Date (as defined below), including the Prospectus (as defined below), all exhibits thereto (excluding the Form T-1, except where otherwise stated) and the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement as of the Effective Date ("Rule 430 Information"), is referred to herein as the "Registration Statement"; "Effective Date" means the effective date of the Registration Statement pursuant to Rule 430B under the Securities Act for purposes of liability under Section 11 of the Securities Act of the Bank or the Underwriters with respect to the offering of the Securities; "Base Prospectus" means the base prospectus, dated November 5, 2024, filed as part of the Registration Statement, relating to the Securities; "Preliminary Prospectus" means the Base Prospectus, as supplemented by the preliminary prospectus supplement specifically relating to the Securities, in the form in which it was most recently filed with the Commission pursuant to Rule 424(b) under the Securities Act and provided to the Representatives for use by the Underwriters in connection with the offering of the Securities; "Prospectus" means the Base Prospectus, as supplemented by the definitive prospectus supplement specifically relating to the Securities, in the form in which it is filed with the Commission pursuant to Rule 424(b) under the Securities Act in accordance with Section 3(a) hereof, including any documents incorporated by reference therein as of the date of such filing. Any reference in this Agreement to the Registration Statement, the Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 6 of Form F-3 under the Securities Act as of the Effective Date of the Registration Statement or the date of such Preliminary Prospectus or the Prospectus, as the case may be, and any reference to "amend", "amendment" or "supplement" with respect to the Registration Statement, the Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the "Exchange Act") that are deemed to be incorporated by reference therein.

The Bank maintains a system of internal controls designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with applicable accounting standards, which system includes policies and procedures that (A) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Bank and its consolidated entities, (B) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with applicable accounting standards, and that receipts and expenditures of the Bank are being made only in accordance with authorizations of management and directors of the Bank, and (C) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Bank's assets that could have a material effect on the financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xi) <u>Disclosure Controls and Procedures</u>.

The Transaction Documents and the Securities are, in all material respects, in proper legal form under the laws of Australia and any political subdivision thereof for the enforcement thereof against the Bank in such jurisdictions. It is not necessary to ensure the legality, validity, enforceability or admissibility in evidence of the Transaction Documents or the Securities in Australia or any political subdivision thereof that any of them be filed or recorded or enrolled with any court, authority or agency in, or that any stamp, registration or similar taxes or duties be paid to any court, authority or agency of Australia or any political subdivision thereof.

There are no material contracts or documents which are required to be described in the Registration Statement, the Time of Sale Information and the Prospectus or the documents incorporated by reference therein or to be filed as exhibits thereto which have not been so described and filed as required.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xxxiii) <u>Investment Company Act</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) *Amendments or Supplements; Issuer Free Writing Prospectuses*. Before using, authorizing, approving, referring to or filing any Issuer Free Writing Prospectus relating to the Securities, and before filing any amendment or supplement to the Registration Statement or the Prospectus, in each case prior to the expiry of the Prospectus Delivery Period (as defined below), whether before or after the time that the Registration Statement becomes effective, the Bank will furnish to the Representatives and counsel for the Underwriters a copy of the proposed Issuer Free Writing Prospectus, amendment or supplement for review and will not use or refer to, or authorize or approve others to use or refer to, in each case in connection with the offering of the Securities, or file with the Commission, any such Issuer Free Writing Prospectus or file any such proposed amendment or supplement to which the Representatives reasonably object and shall have given notice of such objection to the Bank in a timely manner.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) *Notice to the Representatives*. The Bank will advise the Representatives promptly, and confirm such advice in writing, (i) when the Registration Statement has become effective, if it is not effective prior to the date of this Agreement; (ii) when any amendment to the Registration Statement has been filed or becomes effective; (iii) when any supplement to the Prospectus or any amendment to the Prospectus or any Issuer Free Writing Prospectus has been filed; (iv) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or the receipt of any comments from the Commission relating to the Registration Statement or any other request by the Commission for any additional information; (v) of the issuance by the Commission of any order suspending the effectiveness of the Registration Statement, any notice objecting to its use pursuant to Rule 401(g)(2), or any order preventing or suspending the use of any Preliminary Prospectus or the Prospectus or the initiation or threatening of any proceeding for that purpose or pursuant to Section 8A of the Securities Act; (vi) of the occurrence of any event within the Prospectus Delivery Period as a result of which the Prospectus or the Time of Sale Information as then amended or supplemented would include any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus or the Time of Sale Information is delivered to a purchaser, not misleading; and (vii) of the receipt by the Bank of any notice with respect to any suspension of the qualification of the Securities for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Bank will use its reasonable best efforts to prevent the issuance of any such order suspending the effectiveness of the Registration Statement, preventing or suspending the use of any Preliminary Prospectus or the Prospectus or suspending any such qualification of the Securities and, if any such order is issued, will obtain as soon as possible the withdrawal thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) *Time of Sale Information*. If at any time prior to the Closing Date (i) any event shall occur or condition shall exist as a result of which the Time of Sale Information as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances, not misleading or (ii) it is necessary to amend or supplement the Time of Sale Information to comply with law, the Bank will immediately notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission (to the extent required) and furnish to the Underwriters and to such dealers as the Representatives may designate, such amendments or supplements to the Time of Sale Information as may be necessary so that the statements in the Time of Sale Information as so amended or supplemented will not, in the light of the circumstances, be misleading or so that the Time of Sale Information will comply with law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) *Delivery of Copies*. The Bank will deliver, without charge, to each Underwriter (i) a conformed copy of the Registration Statement as originally filed and each amendment thereto, in each case including all exhibits and consents filed therewith (other than any exhibits or consents incorporated by reference therein) and (ii) during the Prospectus Delivery Period, as many copies of the Prospectus (including all amendments and supplements thereto and documents incorporated by reference therein) and each Issuer Free Writing Prospectus as the Representatives may reasonably request. As used herein, the term "Prospectus Delivery Period" means such period of time after the first date of the public offering of the Securities as in the opinion of counsel for the Underwriters a prospectus relating to the Securities is required by law to be delivered (or required to be delivered but for Rule 172 under the Securities Act) in connection with sales of the Securities by any Underwriter or dealer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) *Continued Compliance with Securities Laws*. If during the Prospectus Delivery Period (i) any event shall occur or condition shall exist as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, not misleading or (ii) it is necessary to amend or supplement the Prospectus to comply with law, the Bank will immediately notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission and furnish to the Underwriters and to such dealers as the Representatives may designate, such amendments or supplements to the Prospectus as may be necessary so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus will comply with law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) *Blue Sky Qualifications*. The Bank will endeavor, in cooperation with the Underwriters, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions of the United States as the Underwriters may request and to which the Bank shall not have objected, and will maintain such qualifications in effect for as long as may be required for the distribution of the Securities and will pay any fee of the Financial Industry Regulatory Authority Inc. ("FINRA") in connection with the review of the offering of the Securities; provided, however, that in connection therewith the Bank shall not be obligated to qualify as a foreign corporation in any jurisdiction in which it is not so qualified or to take any action that would subject itself to taxation in respect of doing business in such jurisdiction or to service of process in suits, other than those arising out of the offering or issuance of the Securities, in any jurisdiction in which it is not otherwise so subject. The Bank will file promptly such statements and reports as may be required by the laws of each jurisdiction in which the Securities have been qualified as above provided. The Bank will promptly advise the Representatives of the receipt by the Bank of any notification with respect to the suspension of the qualification of the Securities for sale in any such state or jurisdiction or the initiating or threatening of any proceeding for such purpose.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) *Earnings Statement*. The Bank will timely file such reports pursuant to the Exchange Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement that satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 of the Commission promulgated thereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) *Lock up*. During the period from the date hereof through the Closing Date, the Bank will not, without the prior written consent of the Representatives, offer, sell, contract to sell or otherwise dispose of, any United States dollar-denominated debt securities issued or guaranteed by the Bank for its own account and having a tenor of more than one year; *provided, however*, that nothing in this Agreement shall prevent the Bank from offering, selling, contracting to sell or otherwise disposing of the United States dollar-denominated debt securities in the United States under the Bank's Medium-Term Notes program and outside the United States under the Bank's European Medium-Term Notes program, and United States dollar-denominated covered bonds in and outside the United States under the Bank's Global Covered Bond Programme.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) *No Stabilization.* The Bank will not take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) *Record Retention*. The Bank will, pursuant to reasonable procedures developed in good faith, retain copies of each Issuer Free Writing Prospectus that is not filed with the Commission in accordance with Rule 433 under the Securities Act.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) *DTC*. The Bank will cooperate with the Underwriters and use its best efforts to permit the Securities to be eligible for clearance and settlement through the facilities of DTC.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m) *Use of Proceeds*. The Bank will use the net proceeds received by it from the sale of the Securities in the manner specified in the Registration Statement, the Time of Sale Information and the Prospectus under "Use of Proceeds".

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) the cost of providing any CUSIP or other identification numbers for the Securities; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) *Termination of Agreement*. If (i) this Agreement is terminated by the Representatives in accordance with the provisions of Section 5 or Section 9 hereof, or (ii) the Bank for any reason fails to tender the Securities for delivery to the Underwriters other than a breach of any representation or warranty contained herein by any Underwriter or the non-performance of any agreement by any Underwriter, the Bank shall reimburse the Underwriters for all of their out of pocket expenses including the reasonable fees and disbursements of counsel for the Underwriters incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

SECTION 6. <u>Indemnification</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) *Indemnification of Underwriters*. The Bank agrees to indemnify and hold harmless each Underwriter, its affiliates, as such term is defined in Rule 405 under the Securities Act, its and their partners, directors and officers and each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus, as amended or supplemented, any Issuer Free Writing Prospectus (when taken together with the Time of Sale Information), any Additional Information (when taken together with the Time of Sale Information) or any Time of Sale Information (collectively, the "Indemnified Disclosure"), or the omission or alleged omission therefrom of a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the prior written consent of the Bank; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) against any and all reasonable expense whatsoever, (including, subject to Section 6(c) hereof, the reasonable fees and disbursements of counsel chosen in accordance with Section 6(c) below), incurred, in investigating, preparing or defending against any litigation, or investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

*provided, however*, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Bank by any Underwriter through the Representatives expressly for use in the Indemnified Disclosure.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) *Indemnification of the Bank, Directors and Officers*. Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Bank, its directors, its officers who signed the Registration Statement, and each person, if any, who controls the Bank within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 6(a) above, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information in reliance upon and in conformity with written information furnished to the Bank by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) *General*. In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to either paragraph (a) or (b) above, such person (the "indemnified party") shall promptly notify the person against whom such indemnity may be sought (the "indemnifying party") in writing and the indemnifying party, upon the request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. Any failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability which it may have otherwise than on account of this indemnity agreement. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and, in the reasonable opinion of counsel to the indemnified party, representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate law firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Underwriters in the case of parties indemnified pursuant to paragraph (a) above and by the Bank in the case of parties indemnified pursuant to paragraph (b) above. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there is a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) *Settlement without Consent if Failure to Reimburse*. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for reasonable fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) above effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7. <u>Contribution</u>. In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in Section 6 is for any reason held to be unenforceable by the indemnified parties although applicable in accordance with its terms, the Bank and the Underwriter in respect of which such indemnity agreement is held to be unenforceable shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the Bank and such Underwriter, as incurred, in such proportions that such Underwriter is responsible for that portion represented by the total commissions and underwriting discounts received by such Underwriter as set forth in the table on the cover page of the Prospectus bears to the total net proceeds (before deducting expenses) received by the Bank from the sale of the Securities, and the Bank is responsible for the balance; provided, however, that no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, each director of the Bank, each officer of the Bank who signed the Registration Statement, and each person, if any, who controls the Bank within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Bank. The Underwriters' respective obligations to contribute pursuant to this Section 7 are several in proportion to the principal amount of securities sold to or through each Underwriter and not joint.

SECTION 8. <u>Representations, Warranties and Agreements to Survive Delivery</u>. All representations, warranties and agreements contained in this Agreement or contained in certificates of officers of the Bank submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of an Underwriter or controlling person of an Underwriter, or by or on behalf of the Bank, and shall survive each delivery of and payment for any of the Securities.

SECTION 9. <u>Termination</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) *Termination*. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Bank, if after execution and delivery of this Agreement and prior to the Closing Date (i) there has been, since the date of this Agreement or since the respective dates as of which information is given in the Registration Statement, the Time of Sale Information or the Prospectus, any material adverse change, or any development that could reasonably be expected to result in a prospective material adverse change, in the condition, financial or otherwise, or in or affecting the earnings or operations of the Bank and its subsidiaries taken as a whole, whether or not arising in the ordinary course of business, which, in the reasonable judgment of the Representatives, makes it impracticable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus; (ii) there shall have occurred any suspension or limitation of trading in securities generally on the New York Stock Exchange, Inc., or any setting of minimum prices for trading on such exchange, or any suspension of trading of any securities of the Bank on any exchange or in the over-the-counter market; (iii) there shall have occurred any banking moratorium declared by United States federal, New York or Australian authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; (iv) after the time and date of this Agreement, there has been any actual or prospective change in Australia or United States tax laws or regulations that materially adversely affects the Securities to be issued pursuant to this Agreement; or (v) there shall have occurred any outbreak or escalation of major hostilities in which the United States or Australia is involved, any declaration of war by Congress or any other national or international calamity or emergency and, in the reasonable judgment of the Representatives, the effect of any such outbreak, escalation, declaration, calamity or emergency makes it impractical to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) *Liabilities*. If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7, 8, 13, 14, 15, 16, 17, 18 and 21 shall survive such termination and remain in full force and effect.

SECTION 10. <u>Default by One or More of the Underwriters</u>. (a) If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Bank on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Bank shall be entitled to a further period of 36 hours within which to procure other persons reasonably satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters or the Bank may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Bank or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Bank agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term "Underwriter" includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases the Securities that a defaulting Underwriter agreed but failed to purchase.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Bank as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Bank shall have the right to require each non-defaulting Underwriter to purchase the principal amount of the Securities that such Underwriter agreed to purchase hereunder plus such Underwriter's <u>pro rata</u> share (based on the principal amount of Securities that such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Bank as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Bank shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Bank, except that the Bank will continue to be liable for the payment of expenses as set forth in Section 4 hereof and except that the provisions of Sections 6 and 7 hereof shall not terminate and shall remain in effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Bank or any non-defaulting Underwriter for damages caused by its default.

SECTION 11. <u>Notices</u>. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

SECTION 13. <u>Consent to Jurisdiction; Appointment of Agent to Accept Service of Process</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Bank irrevocably consents and agrees, for the benefit of the holders from time to time of the Securities, the Underwriters and the other persons referred to in Section 12 hereof that any legal action, suit or proceeding against it with respect to its obligations, liabilities or any other matter arising out of or in connection with this Agreement may be brought in the courts of the State of New York or the courts of the United States located in The City of New York and hereby irrevocably consents and submits to the non-exclusive jurisdiction of each such court in personam, generally and unconditionally with respect to any action, suit or proceeding for itself and in respect of its properties, assets and revenues arising out of or in connection with this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Bank hereby irrevocably designates, appoints and empowers its New York branch, with offices at 575 Fifth Avenue, New York, New York 10017, Attention: Branch Manager, as its designee, appointee and agent to receive, accept and acknowledge for and on its behalf, and its properties, assets and revenues, service of any and all legal process, summons, notices and documents which may be served in any such action, suit or proceeding brought in any United States or State court with respect to its obligations, liabilities or any other matter arising out of or in connection with this Agreement and which may be made on such designee, appointee and agent in accordance with legal procedures prescribed for such courts. If for any reason such designee, appointee and agent hereunder shall cease to be available to act as such, the Bank agrees to designate a new designee, appointee and agent in The City of New York on the terms and for the purposes of this Section 13 satisfactory to the Underwriters. The Bank further hereby irrevocably consents and agrees to the service of any and all legal process, summons, notices and documents out of any of the aforesaid courts in any such action, suit or proceeding by serving a copy thereof upon the relevant agent for service of process referred to in this Section 13 (whether or not the appointment of such agent shall for any reason prove to be ineffective or such agent shall accept or acknowledge such service) or by mailing copies thereof by registered or certified mail, first class, postage prepaid, to the Bank at its address specified in or designated pursuant to this Agreement. The Bank agrees that the failure of any such designee, appointee and agent to give any notice of such service to it shall not impair or affect in any way the validity of such service or any judgment rendered in any action or proceeding based thereon. Nothing herein shall in any way be deemed to limit the ability of the holders of the Securities, the Underwriters and the other persons referred to in Section 12 hereof to serve any such legal process, summons, notices and documents in any other manner permitted by applicable law or to obtain jurisdiction over the Bank or bring actions, suits or proceedings against the Bank in any jurisdiction, and in any manner, as may be permitted by applicable law. The Bank hereby irrevocably and unconditionally waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any of the aforesaid actions, suits or proceedings arising out of or in connection with this Agreement brought in the United States federal courts located in The City of New York or the courts of the State of New York and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The provisions of this Section 13 shall survive any termination of this Agreement, in whole or in part.

SECTION 14. <u>Foreign Taxes</u>. Any amounts payable hereunder, other than payments of interest, principal or premium, if any, in respect of any of the Securities, to an Underwriter shall be made free and clear of and without withholding or deduction for or on account of any and all taxes, levies, imposts, duties, charges or fees of whatsoever nature now or hereafter imposed, levied, collected, deducted or withheld or assessed by or on behalf of Australia or any political subdivision thereof or by any jurisdiction, other than the United States or any taxing authority or political subdivision thereof, in which the Bank has a branch, an office or any agency from which payment is made (a "Taxing Authority"), excluding (i) any such tax which would not have been imposed if such Underwriter had no present or former connection with any such jurisdiction other than the performance of its obligations hereunder, (ii) any income or franchise tax imposed on the net income of such Underwriter by any jurisdiction of which such Underwriter is a resident, citizen or domiciliary, or in which such Underwriter is engaged in business and (iii) any tax imposed that would not have been imposed but for the failure by such Underwriter to comply with any certification, identification or other reporting requirements concerning the nationality, residence, identity or connection with any Taxing Authority if compliance is required by such Taxing Authority as a pre-condition to exemption from, or reduction in rate of, such tax (all such non-excluded taxes, the "Foreign Taxes"). If, by operation of law or otherwise, that portion of amounts payable hereunder represented by Foreign Taxes withheld or deducted cannot be paid or remitted, then amounts payable under this Agreement shall be increased to such amounts as are necessary to yield and remit to such Underwriter amounts which, after deduction of all Foreign Taxes (including all Foreign Taxes payable on such increased payments) equal the amounts that would have been payable if no Foreign Taxes had been so withheld or deducted (the "Additional Amount"); <u>provided</u>, <u>however</u>, that no Additional Amount with respect to any payment or compensation to such Underwriter hereunder shall be required to be paid in the event that such payment or compensation is subject to such Foreign Tax by reason of such Underwriter being connected with the jurisdiction of the Taxing Authority other than by reason of merely receiving payment hereunder.

SECTION 15. <u>Waiver of Sovereign Immunity</u>. To the extent that the Bank or any of its properties, assets or revenues may have or may hereafter become entitled to, or have attributed to it, any right of immunity, on the grounds of sovereignty, from any legal action, suit or proceeding, from the giving of any relief in any such legal action, suit or proceeding, from setoff or counterclaim, from the jurisdiction of any court, from service of process, from attachment upon or prior to judgment, from attachment in aid of execution of judgment, or from execution of judgment, or other legal process or proceeding for the giving of any relief or for the enforcement of any judgment, in any jurisdiction in which proceedings may at any time be commenced, with respect to its obligations, liabilities or any other matter under or arising out of or in connection with this Agreement or the Securities, the Bank hereby irrevocably and unconditionally waives, and agrees not to plead or claim, any such immunity and consents to such relief and enforcement.

SECTION 16. <u>Judgment Currency</u>. The Bank agrees to indemnify each Underwriter against any loss incurred by such Underwriter as a result of any judgment or order being given or made for any amount due hereunder and such judgment or order being expressed and paid in a currency (the "Judgment Currency") other than United States dollars and as a result of any variation as between (i) the rate of exchange at which the United States dollar amount is converted into the Judgment Currency for the purpose of such judgment or order and (ii) the rate of exchange at which such Underwriter would have been able to purchase United States dollars with the amount of the Judgment Currency actually received by such Underwriter had such Underwriter utilized such amount of Judgment Currency to purchase United States dollars as promptly as practicable upon such Underwriter's receipt thereof. The foregoing indemnity shall constitute a separate and independent obligation of the Bank and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term "rate of exchange" shall include any premiums and costs of exchange payable in connection with the purchase of, or conversion into, the relevant currency.

SECTION 17. <u>Joint Activities</u>. The Bank and the Underwriters have agreed to come together to execute the offering of the Securities under this Agreement. In order to give effect to their intention, they have severally agreed to obligations on the terms of this Agreement. In particular, the Bank and the Underwriters acknowledge that activities undertaken jointly, including without limitation, any pricing process, any book-build process, any solicitation process, any allocation process, any price stabilization transactions and any restrictions on the parties, the offer, the sale, the resale or the transfer of any Securities, in each case, undertaken under the terms of this Agreement or any arrangements or understandings which are contemplated by this Agreement are reasonably necessary to implement offers of the Securities under this Agreement. Nothing in this Section 17 affects the rights, obligations, responsibilities or liabilities of the parties in respect of this Agreement or any transaction contemplated by it.

SECTION 18. <u>GOVERNING LAW</u>. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

SECTION 19. <u>Effect of Headings</u>. The Article and Section headings herein are for convenience only and shall not affect the construction hereof.

SECTION 20. <u>Counterparts</u>. This Agreement may be executed in one or more counterparts and, if executed in more than one counterpart, the executed counterparts hereof shall constitute a single instrument. Counterparts may be delivered via facsimile, electronic mail or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes. The words "execution," "signed," "signature," and words of like import in this Agreement or in any other certificate, agreement or document related to this Agreement, the Indenture or the Securities shall include images of manually executed signatures transmitted by facsimile or other electronic format (including, without limitation, "pdf", "tif" or "jpg") and other electronic signatures (including, without limitation, DocuSign and AdobeSign). The use of electronic signatures and electronic records (including, without limitation, any contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall be of the same legal effect, validity and enforceability as a manually executed signature or use of a paper-based recordkeeping system to the fullest extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act and any other applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act or the Uniform Commercial Code.

SECTION 21. <u>Recognition of the U.S. Special Resolution Regimes</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

For purposes of this Section 21, the following terms shall have the following meaning:

"**BHC Act Affiliate**" has the meaning assigned to the term "affiliate" in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k).

WHEREAS, Section 8.1(5) of the Amended Base Indenture provides that the Company may enter into a supplemental indenture to change or eliminate any of the provisions of the Amended Base Indenture, provided that any such change or elimination shall become effective only with respect to any series of Securities which has not been issued as of the execution of such supplemental indenture or when there is no Security Outstanding of any series created prior to the execution of such supplemental indenture which is entitled to the benefit of such provision;

WHEREAS, all conditions and requirements of the Amended Base Indenture necessary to make this Thirty-Sixth Supplemental Indenture a valid, binding and legal instrument in accordance with its terms have been performed and fulfilled by the parties hereto.

NOW, THEREFORE, for and in consideration of the premises and other good and valuable consideration, receipt of which is hereby acknowledged by the parties hereto, the parties hereto hereby agree as follows:

Article I<u><br> DEFINITIONS</u>

Section 1.01 <u>General Definitions</u>. For purposes of this Thirty-Sixth Supplemental Indenture:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Capitalized terms used herein without definition shall have the meanings specified in the Amended Base Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) All references to Articles and Sections, unless otherwise specified, refer to the corresponding Articles and Sections of the Amended Base Indenture; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The terms "herein," "hereof," "hereunder" and other words of similar import refer to this Thirty-Sixth Supplemental Indenture as a whole and not to any particular Article, Section or other subdivision.

Article II<u><br> THE 4.354% NOTES</u>

Section 2.01 <u>Title of Securities</u>. There shall be a series of Securities of the Company designated the "4.354% Notes due July 1, 2030" (the "<u>4.354% Notes</u>").

Section 2.02 <u>Limitation of Aggregate Principal Amount</u>. The aggregate principal amount of the 4.354% Notes shall initially be limited to US$750,000,000. The Company may from time to time, without the consent of the Holders of the 4.354% Notes, create and issue additional notes having the same terms and conditions as the 4.354% Notes in all respects or in all respects except for issue date, issue price and, if applicable, the first date on which interest accrues and the first payment of interest thereon ("<u>Additional 4.354% Notes</u>"). Additional 4.354% Notes issued in this manner will be consolidated with, and will form a single series with, the 4.354% Notes, unless such Additional 4.354% Notes will not be treated as fungible with the 4.354% Notes for U.S. federal income tax purposes. The 4.354% Notes and any such Additional 4.354% Notes would rank equally and ratably.

Section 2.03 <u>Principal Payment Date</u>. The principal amount of the 4.354% Notes Outstanding (together with any accrued and unpaid interest) shall be payable in a single installment on July 1, 2030, which date shall be the Stated Maturity of the 4.354% Notes.

Section 2.04 <u>Interest and Interest Rates</u>. The 4.354% Notes will bear interest on the unpaid principal amount thereof at a rate of 4.354% per year from July 1, 2025, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, until the principal amount of the 4.354% Notes shall have been paid or duly provided for, and interest on the 4.354% Notes shall be payable semi-annually in arrears on January 1 and July 1 of each year, beginning on January 1, 2026. Interest on a 4.354% Note will be paid to the Person in whose name that 4.354% Note was registered at the close of business on the December 17 or June 16, as the case may be, whether or not a Business Day, prior to the applicable Interest Payment Date, except that in the case of the Interest Payment Date that is also the Stated Maturity of the 4.354% Notes, the interest due on such date will be paid to the Person to whom principal is payable upon surrender of such Note at a Place of Payment. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. The amount of interest payable for any period less than a full interest period shall be computed on the basis of a 360-day year consisting of twelve 30-day months and the actual days elapsed in a partial month in such period. Any payment of principal or interest required to be made on an Interest Payment Date that is not a Business Day shall be made on the next succeeding Business Day, and no interest will accrue on that payment for the period from and after such Interest Payment Date to the date of payment on the next succeeding Business Day. For purposes of the 4.354% Notes, "<u>Business Day</u>" means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which banking institutions in Sydney, Australia, New York, New York, or London, United Kingdom are authorized or obligated by law or executive order to close.

Section 2.05 <u>Place of Payment</u>. The Place of Payment where the 4.354% Notes may be presented or surrendered for payment, where the 4.354% Notes may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the 4.354% Notes and the Indenture may be served initially shall be the Corporate Trust Office of the Trustee maintained for that purpose in the Borough of Manhattan, City of New York.

Article III<u><br> THE FLOATING RATE NOTES</u>

Section 3.01 <u>Title of Securities</u>. There shall be a series of Securities of the Company designated the "Floating Rate Notes due July 1, 2030" (the "<u>Floating Rate Notes</u>").

Section 3.02 <u>Limitation of Aggregate Principal Amount</u>. The aggregate principal amount of the Floating Rate Notes shall initially be limited to US$750,000,000. The Company may from time to time, without the consent of the Holders of the Floating Rate Notes, create and issue additional notes having the same terms and conditions as the Floating Rate Notes in all respects or in all respects except for issue date, issue price and, if applicable, the first date on which interest accrues and the first payment of interest thereon ("<u>Additional Floating Rate Notes</u>"). Additional Floating Rate Notes issued in this manner will be consolidated with, and will form a single series with, the Floating Rate Notes, unless such Additional Floating Rate Notes will not be treated as fungible with the Floating Rate Notes for U.S. federal income tax purposes. The Floating Rate Notes and any such Additional Floating Rate Notes would rank equally and ratably.

Section 3.03 <u>Principal Payment Date</u>. The principal amount of the Floating Rate Notes Outstanding (together with any accrued and unpaid interest) shall be payable in a single installment on July 1, 2030, which date shall be the Stated Maturity of the Floating Rate Notes.

Section 3.04 <u>Interest and Interest Rates</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Floating Rate Notes will bear interest on the unpaid principal amount thereof from July 1, 2025, or from the most recent Floating Rate Interest Payment Date (as defined below) to which interest has been paid or duly provided for, until the principal amount of the Floating Rate Notes shall have been paid or duly provided for. The interest rate per annum for the Floating Rate Notes will be reset quarterly on the first day of each Floating Rate Interest Period (as defined below) and will be equal to Compounded SOFR (as defined below) plus a margin of 82 basis points, as determined by a calculation agent (the "<u>Calculation Agent</u>"). The Bank of New York Mellon will initially act as Calculation Agent pursuant to the Calculation Agency Agreement, dated as of December 9, 2010, between the Company and the Calculation Agent (the "<u>Calculation Agency Agreement</u>"). The amount of interest accrued and payable on the Floating Rate Notes for each Floating Rate Interest Period will be equal to the product of (i) the Outstanding principal amount of the Floating Rate Notes multiplied by (ii) the product of (a) the interest rate for the relevant Floating Rate Interest Period (as defined below) multiplied by (b) the quotient of the actual number of calendar days in such Interest Period divided by 360.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Interest on the Floating Rate Notes shall be payable quarterly in arrears on each January 1, April 1, July 1 and October 1 (each such date, a "<u>Floating Rate Interest Payment Date</u>"), beginning on October 1, 2025. If any Floating Rate Interest Payment Date would fall on a day that is not a Business Day, other than the Floating Rate Interest Payment Date that is also the Stated Maturity of the Floating Rate Notes, that Floating Rate Interest Payment Date will be postponed to the following day that is a Business Day, except that if such next Business Day is in a different month, then that Floating Rate Interest Payment Date will be the immediately preceding day that is a Business Day. If the Stated Maturity of the Floating Rate Notes is not a Business Day, payment of principal and interest on the Floating Rate Notes will be made on the following day that is a Business Day and no interest will accrue for the period from and after such Stated Maturity of the Floating Rate Notes. Interest on a Floating Rate Note will be paid to the Person in whose name that Floating Rate Note was registered at the close of business on the December 17, March 17, June 16 or September 16, as the case may be, whether or not a Business Day, prior to the applicable Floating Rate Interest Payment Date, except that in the case of the Floating Rate Interest Payment Date that is also the Stated Maturity of the Floating Rate Notes, the interest due on such date will be paid to the Person to whom principal is payable upon surrender of such Floating Rate Note at a Place of Payment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) On each Floating Rate Interest Payment Date, the Company will pay interest for the Floating Rate Interest Period ended on the day immediately preceding such Floating Rate Interest Payment Date. "<u>Floating Rate Interest Period</u>" shall mean the period commencing on and including July 1, 2025 to but excluding the first Floating Rate Interest Payment Date and each successive period from and including a Floating Rate Interest Payment Date to but excluding the next Floating Rate Interest Payment Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The interest rate on the Floating Rate Notes for each Floating Rate Interest Period will be equal to Compounded SOFR (as deﬁned herein) plus a margin of 82 basis points. "Compounded SOFR" will be determined by the Calculation Agent in accordance with the following formula:

![](tm2519266d1_ex4-1img001.jpg)

where:

"d0," for any Observation Period, is the number of U.S. Government Securities Business Days in the relevant Observation Period;

"i" is a series of whole numbers from one to d0, each representing the relevant U.S. Government Securities Business Day in chronological order from, and including, the ﬁrst U.S. Government Securities Business Day in the relevant Observation Period;

"SOFRi," for any U.S. Government Securities Business Day "i" in the relevant Observation Period, is equal to SOFR in respect of that day "i";

"ni," for any U.S. Government Securities Business Day "i" in the relevant Observation Period, is the number of calendar days from, and including, such U.S. Government Securities Business Day "i" to, but excluding, the following U.S. Government Securities Business Day ("i+1"); and

"d" is the number of calendar days in the relevant Observation Period.

For these calculations, the daily SOFR in eﬀect on any U.S. Government Securities Business Day will be the applicable SOFR as reset on that date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) For purposes of determining Compounded SOFR, "SOFR" means, with respect to any U.S. Government Securities Business Day:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the Secured Overnight Financing Rate published for such U.S. Government Securities Business Day as such rate appears on the Federal Reserve Bank of New York's Website at 3:00

p.m. (New York time) on the immediately following U.S. Government Securities Business Day (the "SOFR Determination Time"); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) if the rate speciﬁed in (i) above does not so appear, unless both a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the Secured Overnight Financing Rate as published in respect of the ﬁrst preceding U.S. Government Securities Business Day for which the Secured Overnight Financing Rate was published on the Federal Reserve Bank of New York's Website.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) Notwithstanding anything to the contrary herein, if the Company or its designee (which may be an independent financial advisor or other designee of the Company (any of such entities, a ''Designee'')), determines on or prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date (each as deﬁned below) have occurred with respect to determining Compounded SOFR, then the benchmark replacement provisions set forth herein will thereafter apply to all determinations of the rate of interest payable on the Floating Rate Notes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) For the avoidance of doubt, in accordance with the benchmark replacement provisions, after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the interest payable for each Floating Rate Interest Period on the Floating Rate Notes will be an annual rate equal to the sum of the Benchmark Replacement (as deﬁned below) and the applicable margin.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) <u>Eﬀect of Benchmark Transition Event</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Benchmark Replacement. If the Company or its Designee determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any determination of the Benchmark on any date, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Floating Rate Notes in respect of such determination on such date and all determinations on all subsequent dates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, the Company or its Designee will have the right to make Benchmark Replacement Conforming Changes from time to time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) Decisions and Determinations. Any determination, decision or election that may be made by the Company or its Designee pursuant to the benchmark replacement provisions herein, including any determination with respect to tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) will be conclusive and binding absent manifest error;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) if made by the Company, will be made in its sole discretion;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(C) if made by the Company's Designee, will be made after consultation with the Company, and the Designee will not make any such determination, decision or election to which the Company objects; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(D) shall become eﬀective without consent from any other party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Any determination, decision or election pursuant to the benchmark replacement provisions not made by the Company's Designee will be made by the Company on the basis set forth above. The Designee shall have no liability for not making any such determination, decision or election. In addition, the Company may designate an entity (which may be the Company's aﬃliate) to make any determination, decision or election that the Company has the right to make in connection with the benchmark replacement provisions set forth herein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) <u>Certain Deﬁned Terms</u>. As used herein:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) the sum of: (I) the ISDA Fallback Rate and (II) the Benchmark Replacement Adjustment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(C) the sum of: (I) the alternate rate of interest that has been selected by the Company or its Designee as the replacement for the then-current Benchmark for the applicable Corresponding Tenor giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar denominated Floating Rate Notes at such time and (II) the Benchmark Replacement Adjustment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) "Benchmark Replacement Adjustment" means the ﬁrst alternative set forth in the order below that can be determined by the Company or its Designee as of the Benchmark Replacement Date:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) the spread adjustment, or method for calculating or determining such spread adjustment (which may be a positive or negative value or zero) that has been selected or recommended by the Relevant Governmental Body for the applicable Unadjusted Benchmark Replacement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, then the ISDA Fallback Adjustment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(C) the spread adjustment (which may be a positive or negative value or zero) that has been selected by the Company or its Designee giving due consideration to any industry-accepted spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar denominated Floating Rate Notes at such time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) "Benchmark Replacement Conforming Changes" means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the deﬁnitions or interpretations of Floating Rate Interest Period, the timing and frequency of determining rates and making payments of interest, the rounding of amounts or tenors, and other administrative matters) that the Company or its Designee decides may be appropriate to reﬂect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company or its Designee decides that adoption of any portion of such market practice is not administratively feasible or if the Company or its Designee determines that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company or its Designee determines is reasonably practicable).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) in the case of clause (C) of the deﬁnition of "Benchmark Transition Event," the date of the public statement or publication of information referenced therein.

For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) The interest rate and amount of interest to be paid on the Floating Rate Notes for each Floating Rate Interest Period will be determined by the Calculation Agent. All determinations made by the Calculation Agent shall, in the absence of manifest error, be conclusive for all purposes and binding on the Company and the Holders. So long as Compounded SOFR is required to be determined with respect to the Floating Rate Notes, there will at all times be a Calculation Agent. In the event that any then acting Calculation Agent shall be unable or unwilling to act, or that such Calculation Agent shall fail duly to establish Compounded SOFR for any Floating Rate Interest Period, or the Company proposes to remove such Calculation Agent, the Company shall appoint another Calculation Agent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) In no event shall the Calculation Agent be the Company's Designee. The Calculation Agent shall have no liability for any determination made by or on behalf of the Company or its Designee in connection with a Benchmark Transition Event or a Benchmark Replacement or any adjustments or conforming changes thereto. In no event shall the Calculation Agent be responsible for determining any substitute for SOFR or any Benchmark Replacement, or for determining whether any Benchmark Transition Event has occurred or for making any Benchmark Replacement Adjustments or Benchmark Replacement Conforming Changes. In connection with the foregoing, the Calculation Agent will be entitled to conclusively rely on any determinations made by the Company or its Designee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) In no event shall the interest rate on the Floating Rate Notes be higher than the maximum rate permitted by New York law, as the same may be modified by United States law of general application. Additionally, the interest rate on the Floating Rate Notes will in no event be lower than zero.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m) All percentages resulting from any of the calculations in this Article III will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards).

Section 3.05 <u>Place of Payment</u>. The Place of Payment where the Floating Rate Notes may be presented or surrendered for payment, where the Floating Rate Notes may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Floating Rate Notes and the Indenture may be served initially shall be the Corporate Trust Office of the Trustee maintained for that purpose in the Borough of Manhattan, City of New York.

Section 3.06 <u>Redemption</u>. The Company shall not have the right to redeem the Floating Rate Notes other than pursuant to Section 10.8 of the Indenture.

If the Company elects to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee's understanding of such Instructions shall be deemed controlling. The Company understands and agrees that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Company shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Company and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Company. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee's reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction, except as may result from its own gross negligence, bad faith or willful misconduct. The Company agrees: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions (unless the Trustee has acted on such unauthorized Instructions with gross negligence, in bad faith or with willful misconduct), and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Company; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures.

"<u>Electronic Means</u>" shall mean the following communications methods: e-mail, facsimile transmission, secure electronic transmission containing applicable authorization codes, passwords and/or authentication keys issued by the Trustee, or another method or system specified by the Trustee as available for use in connection with its services hereunder.

Section 4.03 <u>Integral Part; Effect of Supplement on Indenture</u>. This Thirty-Sixth Supplemental Indenture constitutes an integral part of the Indenture. Except for the amendments and supplements made by this Thirty-Sixth Supplemental Indenture, the Amended Base Indenture shall remain in full force and effect as executed.

Section 4.04 <u>Adoption, Ratification and Confirmation</u>. The Indenture, as amended and supplemented by this Thirty-Sixth Supplemental Indenture, is in all respects hereby adopted, ratified and confirmed.

Section 4.05 <u>Trustee Not Responsible for Recitals</u>. The recitals in this Thirty-Sixth Supplemental Indenture shall be taken as statements of the Company, and the Trustee assumes no responsibility for their

correctness. The Trustee makes no representations as to the validity or adequacy of this Thirty-Sixth Supplemental Indenture.

Section 4.06 <u>Counterparts</u>. This Thirty-Sixth Supplemental Indenture may be executed in any number of counterparts, each of which shall be an original but such counterparts shall together constitute but one instrument.

Section 4.07 <u>Separability</u>. In case any provision of this Thirty-Sixth Supplemental Indenture shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

WESTPAC BANKING CORPORATION

4.354% NOTE DUE JULY 1, 2030

WESTPAC BANKING CORPORATION, a company incorporated in the Commonwealth of Australia under the Corporations Act 2001 of the Commonwealth of Australia and registered in New South Wales (the "<u>Company</u>", which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to or registered assigns, the principal sum of (US$) on July 1, 2030 (the "<u>Stated Maturity</u>"). This Note will bear interest on the unpaid principal amount hereof at a rate of 4.354% per year from July 1, 2025, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, until the principal amount hereof shall have been paid or duly provided for, and interest on the Notes shall be payable semi-annually in arrears on January 1 and July 1 of each year (each such date, an "<u>Interest Payment Date</u>"), beginning on January 1, 2026. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. The amount of interest payable for any period less than a full interest period shall be computed on the basis of a 360-day year consisting of twelve 30-day months and the actual days elapsed in a partial month in such period. Any payment of principal or interest required to be made on an Interest Payment Date that is not a Business Day shall be made on the next succeeding Business Day, and no interest will accrue on that payment for the period from and after such Interest Payment Date to the date of payment on the next succeeding Business Day. For purposes hereof, "<u>Business Day</u>" means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which banking institutions in Sydney, Australia, New York, New York, or London, United Kingdom are authorized or obligated by law or executive order to close.

Interest on this Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the close of business on the December 17 or June 16 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date, at the office or agency maintained for such purpose pursuant to the Indenture; provided, however, that at the option of the Company, interest on this Note may be paid (<u>i</u>) by check mailed to the address of the Person entitled thereto as it shall appear on the Register or (<u>ii</u>) to a Holder of US$1,000,000 or more in aggregate principal amount of the Notes by wire transfer to an account maintained by the Person entitled thereto as specified in the Register. Any interest on this Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "<u>Defaulted Interest</u>") shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest shall instead be payable to the Person in whose name this Note is registered on the Special Record Date or other specified date in accordance with the Indenture. Notwithstanding the foregoing, interest payable on an Interest Payment Date that is also the Stated Maturity of this Note will be paid at such office or agency to the Person to whom the principal hereof is payable, upon surrender of this Note at such office or agency.

This Note shall not be entitled to any benefit under the Indenture hereinafter referred to or be valid or become obligatory for any purpose until the Certificate of Authentication hereon shall have been signed by or on behalf of the Trustee.

The provisions of this Note are continued on the reverse side hereof and such continued provisions shall for all purposes have the same effect as though fully set forth at this place. IN WITNESS WHEREOF, the Company has caused this instrument to be executed on this 1<sup>st</sup> day of July, 2025.

(FORM OF REVERSE OF NOTE)

This Note is one of a duly authorized series of securities of the Company, issued and to be issued in one or more series under and pursuant to a Senior Indenture, dated as of July 1, 1999 (the "<u>Base Indenture</u>"), duly executed and delivered between the Company and The Bank of New York Mellon, as successor to The Chase Manhattan Bank, as trustee (the "<u>Trustee</u>", which term includes any successor trustee under the Indenture), as amended and supplemented by the First Supplemental Indenture, dated as of August 27, 2009, between the Company and the Trustee (the "<u>First Supplemental Indenture</u>"), the Fifth Supplemental Indenture, dated as of August 14, 2012, between the Company and the Trustee (the "<u>Fifth Supplemental Indenture</u>"), the Seventeenth Supplemental Indenture, dated as of November 9, 2016, between the Company and the Trustee (the "<u>Seventeenth Supplemental Indenture</u>") and the Twenty-Fifth Supplemental Indenture, dated as of November 9, 2018, between the Company and the Trustee (the "<u>Twenty-Fifth Supplemental Indenture</u>"; the Base Indenture as amended and supplemented by the First Supplemental Indenture, the Fifth Supplemental Indenture, the Seventeenth Supplemental Indenture and the Twenty-Fifth Supplemental Indenture is referred to herein as the "<u>Amended Base Indenture</u>"), and as further amended and supplemented by the Thirty-Sixth Supplemental Indenture, dated as of July 1, 2025, between the Company and the Trustee (the "<u>Thirty-Sixth Supplemental Indenture</u>"; the Amended Base Indenture, as further amended and supplemented by the Thirty-Sixth Supplemental Indenture, is referred to herein as the "<u>Indenture</u>"), to which Indenture and all Indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. This Note is one of a series of securities designated on the face hereof (the "<u>Notes</u>"). The Notes are issued pursuant to the Indenture and are limited in aggregate principal amount to US$750,000,000; *provided, however,* that the Company may from time to time, without the consent of the Holders of the Notes, create and issue additional notes having the same terms and conditions as the Notes in all respects or in all respects except for issue date, issue price and, if applicable, the first date on which interest accrues and the first payment of interest thereon. Additional notes issued in this manner will be consolidated with, and will form a single series with, the Notes, unless such additional notes will not be treated as fungible with the Notes for U.S. federal income tax purposes. The Notes and any such additional notes would rank equally and ratably.

In accordance with Section 10.8 of the Indenture, pursuant to the procedure set forth in Article X of the Indenture, the Company may, at its option, redeem all, but not less than all, of the Notes if (<u>a</u>) there is a change in or any amendment to the laws or regulations (<u>i</u>) of the Commonwealth of Australia, or any political subdivision or taxing authority thereof or therein, or (<u>ii</u>) in the event of the assumption pursuant to Section 7.1 of the Indenture of the obligations of the Company under the Indenture and this Note by an entity organized under the laws of a country other than the Commonwealth of Australia or a political subdivision of a country other than the Commonwealth of Australia, of the Commonwealth of Australia or the country in which such entity is organized or resident or deemed resident for tax purposes or any political subdivision or taxing authority thereof or therein, or (<u>b</u>) there is a change in any application or interpretation of any such laws or regulations, which change or amendment becomes effective, (<u>i</u>) with respect to taxes imposed by the Commonwealth of Australia or any political subdivision or taxing authority thereof or therein, on or after the date the Company originally issued this Note, or (<u>ii</u>) in the event of the assumption pursuant to Section 7.1 of the Indenture of the obligations of the Company under the Indenture and this Note by an entity organized under the laws of a country other than the Commonwealth of Australia or a political subdivision of a country other than the Commonwealth of Australia, with respect to taxes imposed by a non-Australian jurisdiction, on or after the date of the transaction resulting in such assumption, and, in each case, as a result of such change or amendment (<u>1</u>) the Company is or will become obligated to pay any additional amounts on this Note pursuant to Section 9.8 of the Indenture or (<u>2</u>) the Company would not be entitled to claim a deduction in computing its taxation liabilities in respect of (<u>A</u>) any payments of interest or additional amounts or (<u>B</u>) any original issue discount on this Note.

Before the Company may redeem this Note, it must give the Holder of this Note at least 30 days' written notice and not more than 60 days' written notice of its intention to redeem this Note, provided that if the earliest date on which (<u>i</u>) the Company will be obligated to pay any additional amounts, or (<u>ii</u>) the Company would not be entitled to claim a deduction in respect of any payments of interest or additional amounts on or any original issue discount in respect of this Note in computing its taxation liabilities, would occur less than 45 days after the relevant change or amendment to the applicable laws, regulations, determinations or guidelines, the Company may give less than 30 days' written notice but in no case less than 15 days' written notice, provided it gives such notice as soon as practicable in all the circumstances.

The Redemption Price for this Note shall equal 100% of the principal amount of this Note plus accrued but unpaid interest to but excluding the date of redemption.

The Indenture contains provisions for defeasance and covenant defeasance at any time of the indebtedness evidenced by this Note upon compliance by the Company with certain conditions set forth therein.

If an Event of Default shall have occurred and be continuing, the principal hereof may be declared, and upon such declaration become, due and payable immediately, in the manner, with the effect and subject to the conditions provided in the Indenture. The Indenture contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Outstanding Notes, on behalf of all of the Holders of the Notes, to waive any Event of Default under the Indenture and its consequences, subject to Section 5.7 of the Indenture.

In accordance with Section 9.8 of the Indenture, the Company will pay all amounts that it is required to pay in respect of this Note without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or other governmental charges imposed or levied by or on behalf of the Commonwealth of Australia or any political subdivision or taxing authority thereof or therein, unless such withholding or deduction is required by law. In that event, the Company will pay such additional amounts as may be necessary so that the net amount received by the Holder of this Note, after such withholding or deduction, will equal the amount that the Holder of this Note would have received in respect of this Note without such withholding or deduction; provided that the Company will pay no additional amounts in respect of this Note for or on account of:

(1) any tax, duty, assessment or other governmental charge that would not have been imposed but for the fact that the Holder, or the beneficial
owner, of this Note was a resident, domiciliary or national of, or engaged in business or maintained a permanent establishment or was
physically present in, the Commonwealth of Australia or any political subdivision or taxing authority thereof or therein or otherwise
had some connection with the Commonwealth of Australia or any political subdivision or taxing authority thereof or therein other than
merely holding this Note or receiving payments under this Note;

(2) any tax, duty, assessment or other governmental charge that would not have been imposed but for the fact that the Holder of this Note
presented this Note for payment in the Commonwealth of Australia, unless the Holder was required to present this Note for payment and
it could not have been presented for payment anywhere else;

(3) any tax, duty, assessment or other governmental charge that would not have been imposed but for the fact that the Holder of this Note
presented this Note for payment more than 30 days after the date such payment became due and was provided for, whichever is later, except
to the extent that the Holder would have been entitled to the additional amounts on presenting this Note for payment on any day during
that 30 day period;

(4) any estate, inheritance, gift, sale, transfer, personal property or similar tax, duty, assessment or other governmental charge;

(5) any tax, duty, assessment or other governmental charge which is payable otherwise than by withholding or deduction;

(6) any tax, duty, assessment or other governmental charge that would not have been imposed if the Holder, or the beneficial owner, of
this Note complied with the Company's request to provide information concerning his, her or its nationality, residence or identity
or to make a declaration, claim or filing or satisfy any requirement for information or reporting that is required to establish the eligibility
of the Holder, or the beneficial owner, of this Note to receive the relevant payment without (or at a reduced rate of) withholding or deduction for or on account of any
such tax, duty, assessment or other governmental charge;

(7) any tax, duty, assessment or other governmental charge that would not have been imposed but for the Holder, or the beneficial owner,
of this Note being an associate of the Company's for purposes of Section 128F of the Income Tax Assessment Act 1936 of the
Commonwealth of Australia, as amended, or any successor act (the " <u>Australian Tax Act</u> ") (other than in the capacity
of a clearing house, paying agent, custodian, funds manager or responsible entity of a registered scheme under the Corporations Act 2001
of the Commonwealth of Australia, as amended, or any successor act);

(8) any tax, duty, assessment or other governmental charge that is imposed or withheld as a consequence of a determination having been
made under Part IVA of the Australian Tax Act (or any modification thereof or provision substituted therefor) by the Australian Commissioner
of Taxation that such tax, duty, assessment or other governmental charge is payable in circumstances where the Holder, or the beneficial
owner, of this Note is a party to or participated in a scheme to avoid such tax which the Company was not a party to;

(9) any tax, duty, assessment or other governmental charge arising under or in connection with Section 1471 to 1474 of the U.S. Internal
Revenue Code of 1986, as amended, including any regulations or official interpretations issued, agreements (including, without limitation,
intergovernmental agreements) entered into or non-U.S. laws enacted with respect thereto (" <u>FATCA</u> "); or

(10) any combination of the foregoing.

Subject to the foregoing, additional amounts will also not be payable by the Company with respect to any payment on this Note to any Holder who is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent that payment would, under the laws of the Commonwealth of Australia or any political subdivision or taxing authority thereof or therein, be treated as being derived or received for tax purposes by a beneficiary or settler of that fiduciary or member of that partnership or a beneficial owner, in each case, who would not have been entitled to those additional amounts had it been the actual Holder of this Note.

If, as a result of the Company's consolidation or merger with or into an entity organized under the laws of a country other than the Commonwealth of Australia or a political subdivision of a country other than the Commonwealth of Australia or the sale, conveyance or transfer by the Company of all or substantially all its assets to such an entity, such an entity assumes the obligations of the Company, such entity will pay additional amounts on the same basis, except that references to "the Commonwealth of Australia" (other than in clause (7) above) will be treated as references to both the Commonwealth of Australia and the country in which such entity is organized or resident (or deemed resident for tax purposes).

The Company, and any other Person to or through which any payment with respect to this Note may be made, shall be entitled to withhold or deduct from any payment with respect to this Note amounts required to be withheld or deducted under or in connection with FATCA, and Holders and beneficial owners of this Note shall not be entitled to receive any gross up or other additional amounts on account of any such withholding or deduction.

All references in this Note to the payment of the principal of or interest on this Note shall be deemed to include the payment of additional amounts to the extent that, in that context, additional amounts are, were or would be payable as provided above.

The Indenture contains provisions permitting the Company and the Trustee, with the written consent of the Holders of not less than a majority in aggregate principal amount (calculated as provided in the Indenture) of the Outstanding Securities of each series adversely affected thereby to add any provisions to or to change or eliminate any provisions of the Indenture or any supplemental indenture or to modify the rights of the Holders of the Securities of such series, provided that, without the consent of the Holder of each such Security so affected, no such modification shall (a) change the Stated Maturity of the principal of, or any installment of principal of or interest on, any Security, or reduce the principal amount of any Security or the rate of interest thereon, or change the coin or currency in which any Security or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity of any Security (or, in the case of redemption, on or after the Redemption Date), or (b) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any such amendment or modification, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of the Indenture or certain defaults thereunder and their consequences) provided for in the Indenture, or (c) change any obligation of the Company to maintain an office or agency in the places and for the purposes specified in Section 9.2 of the Indenture, or (d) except to the extent provided in Section 8.1(9) of the Indenture, make any change in Section 5.2, 5.7, 5.10 or 8.2 of the Indenture except to increase any percentage or to provide that certain other provisions of the Indenture cannot be modified or waived except with the consent of the Holders of each Outstanding Security affected thereby. Any such consent given by the Holder of this Note shall be conclusive and binding upon such Holder and all future Holders of this Note and of any Notes issued on registration hereof, the transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent is made upon this Note.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the place, at the respective time, at the rate and in the coin or currency herein prescribed.

Upon surrender for registration of transfer of this Note, the Company shall execute and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, a new Note or Notes of like tenor and authorized denominations for an equal aggregate principal amount in exchange herefor, subject to the limitations provided in the Indenture. Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company, the Registrar or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company, the Registrar and the Trustee duly executed by the Holder thereof or his attorney duly authorized in writing. No service charge shall be made for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the person in whose name this Note is registered as the owner hereof for all purposes (subject to the provisions hereof with respect to determination of the Person to whom interest is payable).

Reference is made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms upon which the Notes are to be authenticated and delivered.

No past, present or future director, officer, employee, agent, member, manager, trustee or stockholder, as such, of the Company or any successor Person shall have any liability for any obligations of the Company or any successor Person, either directly or through the Company or any successor Person, under the Notes or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation, whether by virtue of any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise. By accepting a Note, each Holder agrees to the provisions of Section 1.13 of the Indenture and waives and releases all such liability. Such waiver and release shall be part of the consideration for the issue of the Notes.

The Notes of this series shall be issuable only in denominations of US$2,000 and integral multiples of US$1,000 in excess thereof. [This Global Note is exchangeable for Notes in definitive form only under certain limited circumstances set forth in the Indenture.]<sup>2</sup> At the option of the Holder, the Notes (except a Note in global form) may be exchanged for other Notes, of any authorized denominations and of a like aggregate principal amount containing identical terms and provisions, upon surrender of the Notes to be exchanged at such office or agency.

All terms used in this Note that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

This Note will bear interest on the unpaid principal amount hereof from July 1, 2025, or from the most recent Interest Payment Date (as defined below) to which interest has been paid or duly provided for, until the principal amount hereof shall have been paid or duly provided for. The interest rate per annum on this Note will be reset quarterly on the first day of each Interest Period (as defined below) and will be equal to Compounded SOFR (as defined below) plus a margin of 82 basis points, as determined by a calculation agent (the "Calculation Agent"). The Bank of New York Mellon will initially act as Calculation Agent. The amount of interest accrued and payable on this Note for each Interest Period will be equal to the product of (i) the Outstanding principal amount of this Note multiplied by (ii) the product of (a) the interest rate for the relevant Interest Period multiplied by (b) the quotient of the actual number of calendar days in such Interest Period divided by 360.

Interest on this Note shall be payable quarterly in arrears on each January 1, April 1, July 1 and October 1 (each such date, an "Interest Payment Date"), beginning on October 1, 2025. If any Interest Payment Date would fall on a day that is not a Business Day, other than the Interest Payment Date that is also the Stated Maturity for this Note, that Interest Payment Date will be postponed to the following day that is a Business Day, except that if such next Business Day is in a different month, then that Interest Payment Date will be the immediately preceding day that is a Business Day. If the Stated Maturity for this Note is not a Business Day, payment of principal and interest on this Note will be made on the following day that is a Business Day and no interest will accrue for the period from and after such Stated Maturity.

On each Interest Payment Date, the Company will pay interest for the Interest Period ended on the day immediately preceding such Interest Payment Date. "Interest Period" shall mean the period commencing on and including July 1, 2025 to but excluding the first Interest Payment Date and each successive period from and including an Interest Payment Date to but excluding the next Interest Payment Date.

The interest rate on this Note for each Interest Period will be equal to Compounded SOFR (as deﬁned herein) plus a margin of 82 basis points. "Compounded SOFR" will be determined by the Calculation Agent in accordance with the following formula:

![](tm2519266d1_ex4-1img002.jpg)

where:

"d0," for any Observation Period, is the number of U.S. Government Securities Business Days in the relevant Observation Period;

"i" is a series of whole numbers from one to d0, each representing the relevant U.S. Government Securities Business Day in chronological order from, and including, the ﬁrst U.S. Government Securities Business Day in the relevant Observation Period;

"SOFRi," for any U.S. Government Securities Business Day "i" in the relevant Observation Period, is equal to SOFR in respect of that day "i";

"ni," for any U.S. Government Securities Business Day "i" in the relevant Observation Period, is the number of calendar days from, and including, such U.S. Government Securities Business Day "i" to, but excluding, the following U.S. Government Securities Business Day ("i+1"); and

"d" is the number of calendar days in the relevant Observation Period.

For these calculations, the daily SOFR in eﬀect on any U.S. Government Securities Business Day will be the applicable SOFR as reset on that date.

For purposes of determining Compounded SOFR, "SOFR" means, with respect to any U.S. Government Securities Business Day:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) the Secured Overnight Financing Rate published for such U.S. Government Securities Business Day as such rate appears on the Federal Reserve Bank of New York's Website at 3:00 p.m. (New York time) on the immediately following U.S. Government Securities Business Day (the "SOFR Determination Time"); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) if the rate speciﬁed in (i) above does not so appear, unless both a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the Secured Overnight Financing Rate as published in respect of the ﬁrst preceding U.S. Government Securities Business Day for which the Secured Overnight Financing Rate was published on the Federal Reserve Bank of New York's Website.

Notwithstanding anything to the contrary herein, if the Company or its designee (which may be an independent financial advisor or other designee of the Company (any of such entities, a ''Designee'')), determines on or prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date (each as deﬁned below) have occurred with respect to determining Compounded SOFR, then the benchmark replacement provisions set forth herein will thereafter apply to all determinations of the rate of interest payable on this Note.

For the avoidance of doubt, in accordance with the benchmark replacement provisions, after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the interest payable for each Interest Period on this Note will be an annual rate equal to the sum of the Benchmark Replacement (as deﬁned below) and the applicable margin.

Eﬀect of Benchmark Transition Event

Benchmark Replacement. If the Company or its Designee determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any determination of the Benchmark on any date, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to this Note in respect of such determination on such date and all determinations on all subsequent dates.

Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, the Company or its Designee will have the right to make Benchmark Replacement Conforming Changes from time to time.

Decisions and Determinations. Any determination, decision or election that may be made by the Company or its Designee pursuant to the benchmark replacement provisions herein, including any determination with respect to tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) will be conclusive and binding absent manifest error;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) if made by the Company, will be made in its sole discretion;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) if made by the Company's Designee, will be made after consultation with the Company, and the Designee will not make any such determination, decision or election to which the Company objects; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) shall become eﬀective without consent from any other party.

Any determination, decision or election pursuant to the benchmark replacement provisions not made by the Company's Designee will be made by the Company on the basis set forth above. The Designee shall have no liability for not making any such determination, decision or election. In addition, the Company may designate an entity (which may be the Company's aﬃliate) to make any determination, decision or election that the Company has the right to make in connection with the benchmark replacement provisions set forth herein.

Certain Deﬁned Terms. As used herein:

"Benchmark" means, initially, Compounded SOFR, as such term is deﬁned above; provided that if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Compounded SOFR (or the published daily SOFR used in the calculation thereof) or the then-current Benchmark, then "Benchmark" means the applicable Benchmark Replacement.

"Benchmark Replacement" means the ﬁrst alternative set forth in the order below that can be determined by the Company or its Designee as of the Benchmark Replacement Date:

(1) the sum of: (a) an alternate rate of interest that has been selected or recommended by the Relevant Governmental Body as the replacement for the then-current Benchmark for the applicable Corresponding Tenor and (b) the Benchmark Replacement Adjustment;

(2) the sum of: (a) the ISDA Fallback Rate and (b) the Benchmark Replacement Adjustment; and

(3) the sum of: (a) the alternate rate of interest that has been selected by the Company or its Designee as the replacement for the then-current Benchmark for the applicable Corresponding Tenor giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar denominated floating rate notes at such time and (b) the Benchmark Replacement Adjustment.

"Benchmark Replacement Adjustment" means the ﬁrst alternative set forth in the order below that can be determined by the Company or its Designee as of the Benchmark Replacement Date:

(1) the spread adjustment, or method for calculating or determining such spread adjustment (which may be a positive or negative value or zero) that has been selected or recommended by the Relevant Governmental Body for the applicable Unadjusted Benchmark Replacement;

(2) if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, then the ISDA Fallback Adjustment; and

(3) the spread adjustment (which may be a positive or negative value or zero) that has been selected by the Company or its Designee giving due consideration to any industry-accepted spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar denominated floating rate notes at such time.

"Benchmark Replacement Conforming Changes" means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the deﬁnitions or interpretations of Interest Period, the timing and frequency of determining rates and making payments of interest, the rounding of amounts or tenors, and other administrative matters) that the Company or its Designee decides may be appropriate to reﬂect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company or its Designee decides that adoption of any portion of such market practice is not administratively feasible or if the Company or its Designee determines that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company or its Designee determines is reasonably practicable).

"Benchmark Replacement Date" means the earliest to occur of the following events with respect to the then-current Benchmark:

(2) in the case of clause (3) of the deﬁnition of "Benchmark Transition Event," the date of the public statement or publication of information referenced therein.

For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

"Benchmark Transition Event" means the occurrence of one or more of the following events with respect to the then-current Benchmark:

(1) a public statement or publication of information by or on behalf of the administrator of the Benchmark announcing that such administrator has ceased or will cease to provide the Benchmark, permanently or indeﬁnitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark;

(2) a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark, the central bank for the currency of the Benchmark, an insolvency oﬃcial with jurisdiction over the administrator for the Benchmark, a resolution authority with jurisdiction over the administrator for the Benchmark or a court or an entity with similar insolvency or resolution authority over the administrator for the Benchmark, which states that the administrator of the Benchmark has ceased or will cease to provide the Benchmark permanently or indeﬁnitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark; or

(3) a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark announcing that the Benchmark is no longer representative.

"ISDA Fallback Adjustment" means the spread adjustment, (which may be a positive or negative value or zero) that would apply for derivatives transactions referencing the ISDA Deﬁnitions to be determined upon the occurrence of an index cessation event with respect to the Benchmark for the applicable tenor.

"ISDA Fallback Rate" means the rate that would apply for derivatives transactions referencing the ISDA Deﬁnitions to be eﬀective upon the occurrence of an index cessation date with respect to the Benchmark for the applicable tenor excluding the applicable ISDA Fallback Adjustment.

"Observation Period" means, in respect of each Interest Period, the period from, and including, the date two U.S. Government Securities Business Days preceding the ﬁrst date in such Interest Period to, but excluding, the date two U.S. Government Securities Business Days preceding the Interest Payment Date for such Interest Period.

"Reference Time" with respect to any determination of the Benchmark means (1) if the Benchmark is Compounded SOFR, the SOFR Determination Time, and (2) if the Benchmark is not Compounded SOFR, the time determined by the Company or its Designee in accordance with the Benchmark Replacement Conforming Changes.

"Relevant Governmental Body" means the Federal Reserve Board and/or the Federal Reserve Bank of New York, or a committee oﬃcially endorsed or convened by the Federal Reserve Board and/or the Federal Reserve Bank of New York or any successor thereto.

The interest rate and amount of interest to be paid on this Note for each Interest Period will be determined by the Calculation Agent. All determinations made by the Calculation Agent shall, in the absence of manifest error, be conclusive for all purposes and binding on the Company and the Holders. So long as Compounded SOFR is required to be determined with respect to this Note, there will at all times be a Calculation Agent. In the event that any then acting Calculation Agent shall be unable or unwilling to act, or that such Calculation Agent shall fail duly to establish Compounded SOFR for any Interest Period, or the Company proposes to remove such Calculation Agent, the Company shall appoint another Calculation Agent.

In no event shall the Calculation Agent be the Company's Designee. The Calculation Agent shall have no liability for any determination made by or on behalf of the Company or its Designee in connection with a Benchmark Transition Event or a Benchmark Replacement or any adjustments or conforming changes thereto. In no event shall the Calculation Agent be responsible for determining any substitute for SOFR or any Benchmark Replacement, or for determining whether any Benchmark Transition Event has occurred or for making any Benchmark Replacement Adjustments or Benchmark Replacement Conforming Changes. In connection with the foregoing, the Calculation Agent will be entitled to conclusively rely on any determinations made by the Company or its Designee.

In no event shall the interest rate on this Note be higher than the maximum rate permitted by New York law, as the same may be modified by United States law of general application. Additionally, the interest rate on this Note will in no event be lower than zero.

All percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards).

Interest on this Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the close of business on the December 17, March 17, June 16 or September 16 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date, at the office or agency maintained for such purpose pursuant to the Indenture; provided, however, that at the option of the Company, interest on this Note may be paid (<u>i</u>) by check mailed to the address of the Person entitled thereto as it shall appear on the Register or (<u>ii</u>) to a Holder of US$1,000,000 or more in aggregate principal amount of the Notes by wire transfer to an account maintained by the Person entitled thereto as specified in the Register. Any interest on this Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "<u>Defaulted Interest</u>") shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest shall instead be payable to the Person in whose name this Note is registered on the Special Record Date or other specified date in accordance with the Indenture. Notwithstanding the foregoing, interest payable on an Interest Payment Date that is also the Stated Maturity of this Note will be paid at such office or agency to the Person to whom the principal hereof is payable, upon surrender of this Note at such office or agency.

This Note shall not be entitled to any benefit under the Indenture hereinafter referred to or be valid or become obligatory for any purpose until the Certificate of Authentication hereon shall have been signed by or on behalf of the Trustee.

The provisions of this Note are continued on the reverse side hereof and such continued provisions shall for all purposes have the same effect as though fully set forth at this place.

IN WITNESS WHEREOF, the Company has caused this instrument to be executed on this 1<sup>st</sup> day of July, 2025.

(FORM OF REVERSE OF NOTE)

This Note is one of a duly authorized series of securities of the Company, issued and to be issued in one or more series under and pursuant to a Senior Indenture, dated as of July 1, 1999 (the "<u>Base Indenture</u>"), duly executed and delivered between the Company and The Bank of New York Mellon, as successor to The Chase Manhattan Bank, as trustee (the "<u>Trustee</u>", which term includes any successor trustee under the Indenture), as amended and supplemented by the First Supplemental Indenture, dated as of August 27, 2009, between the Company and the Trustee (the "<u>First Supplemental Indenture</u>"), the Fifth Supplemental Indenture, dated as of August 14, 2012, between the Company and the Trustee (the "<u>Fifth Supplemental Indenture</u>"), the Seventeenth Supplemental Indenture, dated as of November 9, 2016, between the Company and the Trustee (the "<u>Seventeenth Supplemental Indenture</u>") and the Twenty-Fifth Supplemental Indenture, dated as of November 9, 2018, between the Company and the Trustee (the "<u>Twenty-Fifth Supplemental Indenture</u>"; the Base Indenture as amended and supplemented by the First Supplemental Indenture, the Fifth Supplemental Indenture, the Seventeenth Supplemental Indenture and the Twenty-Fifth Supplemental Indenture is referred to herein as the "<u>Amended Base Indenture</u>"), and as further amended and supplemented by the Thirty-Sixth Supplemental Indenture, dated as of July 1, 2025, between the Company and the Trustee (the "<u>Thirty-Sixth Supplemental Indenture</u>"; the Amended Base Indenture, as further supplemented by the Thirty-Sixth Supplemental Indenture, is referred to herein as the "<u>Indenture</u>"), to which Indenture and all Indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. This Note is one of a series of securities designated on the face hereof (the "<u>Notes</u>"). The Notes are issued pursuant to the Indenture and are limited in aggregate principal amount to US$750,000,000; *provided, however,* that the Company may from time to time, without the consent of the Holders of the Notes, create and issue additional notes having the same terms and conditions as the Notes in all respects or in all respects except for issue date, issue price and, if applicable, the first date on which interest accrues and the first payment of interest thereon. Additional notes issued in this manner will be consolidated with, and will form a single series with, the Notes, unless such additional notes will not be treated as fungible with the Notes for U.S. federal income tax purposes. The Notes and any such additional notes would rank equally and ratably.

In accordance with Section 10.8 of the Indenture, pursuant to the procedure set forth in Article X of the Indenture, the Company may, at its option, redeem all, but not less than all, of the Notes if (<u>a</u>) there is a change in or any amendment to the laws or regulations (<u>i</u>) of the Commonwealth of Australia, or any political subdivision or taxing authority thereof or therein, or (<u>ii</u>) in the event of the assumption pursuant to Section 7.1 of the Indenture of the obligations of the Company under the Indenture and this Note by an entity organized under the laws of a country other than the Commonwealth of Australia or a political subdivision of a country other than the Commonwealth of Australia, of the Commonwealth of Australia or the country in which such entity is organized or resident or deemed resident for tax purposes or any political subdivision or taxing authority thereof or therein, or (<u>b</u>) there is a change in any application or interpretation of any such laws or regulations, which change or amendment becomes effective, (<u>i</u>) with respect to taxes imposed by the Commonwealth of Australia or any political subdivision or taxing authority thereof or therein, on or after the date the Company originally issued this Note, or (<u>ii</u>) in the event of the assumption pursuant to Section 7.1 of the Indenture of the obligations of the Company under the Indenture and this Note by an entity organized under the laws of a country other than the Commonwealth of Australia or a political subdivision of a country other than the Commonwealth of Australia, with respect to taxes imposed by a non-Australian jurisdiction, on or after the date of the transaction resulting in such assumption, and, in each case, as a result of such change or amendment (<u>1</u>) the Company is or will become obligated to pay any additional amounts on this Note pursuant to Section 9.8 of the Indenture or (<u>2</u>) the Company would not be entitled to claim a deduction in computing its taxation liabilities in respect of (<u>A</u>) any payments of interest or additional amounts or (<u>B</u>) any original issue discount on this Note.

Before the Company may redeem this Note, it must give the Holder of this Note at least 30 days' written notice and not more than 60 days' written notice of its intention to redeem this Note, provided that if the earliest date on which (<u>i</u>) the Company will be obligated to pay any additional amounts, or (<u>ii</u>) the Company would not be entitled to claim a deduction in respect of any payments of interest or additional amounts on or any original issue discount in respect of this Note in computing its taxation liabilities, would occur less than 45 days after the relevant change or amendment to the applicable laws, regulations, determinations or guidelines, the Company may give less than 30 days' written notice but in no case less than 15 days' written notice, provided it gives such notice as soon as practicable in all the circumstances.

The Redemption Price for this Note shall equal 100% of the principal amount of this Note plus accrued but unpaid interest to but excluding the date of redemption.

The Indenture contains provisions for defeasance and covenant defeasance at any time of the indebtedness evidenced by this Note upon compliance by the Company with certain conditions set forth therein.

If an Event of Default shall have occurred and be continuing, the principal hereof may be declared, and upon such declaration become, due and payable immediately, in the manner, with the effect and subject to the conditions provided in the Indenture. The Indenture contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Outstanding Notes, on behalf of all of the Holders of the Notes, to waive any Event of Default under the Indenture and its consequences, subject to Section 5.7 of the Indenture.

In accordance with Section 9.8 of the Indenture, the Company will pay all amounts that it is required to pay in respect of this Note without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or other governmental charges imposed or levied by or on behalf of the Commonwealth of Australia or any political subdivision or taxing authority thereof or therein, unless such withholding or deduction is required by law. In that event, the Company will pay such additional amounts as may be necessary so that the net amount received by the Holder of this Note, after such withholding or deduction, will equal the amount that the Holder of this Note would have received in respect of this Note without such withholding or deduction; provided that the Company will pay no additional amounts in respect of this Note for or on account of:

(1) any tax, duty, assessment or other governmental charge that would not have been imposed but for the fact that the Holder, or the beneficial
owner, of this Note was a resident, domiciliary or national of, or engaged in business or maintained a permanent establishment or was
physically present in, the Commonwealth of Australia or any political subdivision or taxing authority thereof or therein or otherwise
had some connection with the Commonwealth of Australia or any political subdivision or taxing authority thereof or therein other than
merely holding this Note or receiving payments under this Note;

(2) any tax, duty, assessment or other governmental charge that would not have been imposed but for the fact that the Holder of this Note
presented this Note for payment in the Commonwealth of Australia, unless the Holder was required to present this Note for payment and
it could not have been presented for payment anywhere else;

(3) any tax, duty, assessment or other governmental charge that would not have been imposed but for the fact that the Holder of this Note
presented this Note for payment more than 30 days after the date such payment became due and was provided for, whichever is later, except
to the extent that the Holder would have been entitled to the additional amounts on presenting this Note for payment on any day during
that 30 day period;

(4) any estate, inheritance, gift, sale, transfer, personal property or similar tax, duty, assessment or other governmental charge;

(5) any tax, duty, assessment or other governmental charge which is payable otherwise than by withholding or deduction;

(6) any tax, duty, assessment or other governmental charge that would not have been imposed if the Holder, or the beneficial owner, of
this Note complied with the Company's request to provide information concerning his, her or its nationality, residence or identity
or to make a declaration, claim or filing or satisfy any requirement for information or reporting that is required to establish the eligibility
of the Holder, or the beneficial owner, of this Note to receive the relevant payment without (or at a reduced rate of) withholding or
deduction for or on account of any such tax, duty, assessment or other governmental charge;

(7) any tax, duty, assessment or other governmental charge that would not have been imposed but for the Holder, or the beneficial owner,
of this Note being an associate of the Company's for purposes of Section 128F of the Income Tax Assessment Act 1936 of the
Commonwealth of Australia, as amended, or any successor act (the "Australian Tax Act") (other than in the capacity of a clearing
house, paying agent, custodian, funds manager or responsible entity of a registered scheme under the Corporations Act 2001 of the Commonwealth
of Australia, as amended, or any successor act);

(8) any tax, duty, assessment or other governmental charge that is imposed or withheld as a consequence of a determination having been
made under Part IVA of the Australian Tax Act (or any modification thereof or provision substituted therefor) by the Australian Commissioner
of Taxation that such tax, duty, assessment or other governmental charge is payable
in circumstances where the Holder, or the beneficial owner, of this Note is a party to or participated in a scheme to avoid such tax which
the Company was not a party to;

(9) any tax, duty, assessment or other governmental charge arising under or in connection with Section 1471 to 1474 of the U.S. Internal
Revenue Code of 1986, as amended, including any regulations or official interpretations issued, agreements (including, without limitation,
intergovernmental agreements) entered into or non-U.S. laws enacted with respect thereto ("FATCA"); or

(10) any combination of the foregoing.

Subject to the foregoing, additional amounts will also not be payable by the Company with respect to any payment on this Note to any Holder who is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent that payment would, under the laws of the Commonwealth of Australia or any political subdivision or taxing authority thereof or therein, be treated as being derived or received for tax purposes by a beneficiary or settler of that fiduciary or member of that partnership or a beneficial owner, in each case, who would not have been entitled to those additional amounts had it been the actual Holder of this Note.

If, as a result of the Company's consolidation or merger with or into an entity organized under the laws of a country other than the Commonwealth of Australia or a political subdivision of a country other than the Commonwealth of Australia or the sale, conveyance or transfer by the Company of all or substantially all its assets to such an entity, such an entity assumes the obligations of the Company, such entity will pay additional amounts on the same basis, except that references to "the Commonwealth of Australia" (other than in clause (7) above) will be treated as references to both the Commonwealth of Australia and the country in which such entity is organized or resident (or deemed resident for tax purposes).

The Company, and any other Person to or through which any payment with respect to this Note may be made, shall be entitled to withhold or deduct from any payment with respect to this Note amounts required to be withheld or deducted under or in connection with FATCA, and Holders and beneficial owners of this Note shall not be entitled to receive any gross up or other additional amounts on account of any such withholding or deduction.

All references in this Note to the payment of the principal of or interest on this Note shall be deemed to include the payment of additional amounts to the extent that, in that context, additional amounts are, were or would be payable as provided above.

The Indenture contains provisions permitting the Company and the Trustee, with the written consent of the Holders of not less than a majority in aggregate principal amount (calculated as provided in the Indenture) of the Outstanding Securities of each series adversely affected thereby to add any provisions to or to change or eliminate any provisions of the Indenture or any supplemental indenture or to modify the rights of the Holders of the Securities of such series, provided that, without the consent of the Holder of each such Security so affected, no such modification shall (a) change the Stated Maturity of the principal of, or any installment of principal of or interest on, any Security, or reduce the principal amount of any Security or the rate of interest thereon, or change the coin or currency in which any Security or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity of any Security (or, in the case of redemption, on or after the Redemption Date), or (b) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any such amendment or modification, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of the Indenture or certain defaults thereunder and their consequences) provided for in the Indenture, or (c) change any obligation of the Company to maintain an office or agency in the places and for the purposes specified in Section 9.2 of the Indenture, or (d) except to the extent provided in Section 8.1(9) of the Indenture, make any change in Section 5.2, 5.7, 5.10 or 8.2 of the Indenture except to increase any percentage or to provide that certain other provisions of the Indenture cannot be modified or waived except with the consent of the Holders of each Outstanding Security affected thereby. Any such consent given by the Holder of this Note shall be conclusive and binding upon such Holder and all future Holders of this Note and of any Notes issued on registration hereof, the transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent is made upon this Note.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the place, at the respective time, at the rates and in the coin or currency herein prescribed.

Upon surrender for registration of transfer of this Note, the Company shall execute and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, a new Note or Notes of like tenor and authorized denominations for an equal aggregate principal amount in exchange herefor, subject to the limitations provided in the Indenture. Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company, the Registrar or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company, the Registrar and the Trustee duly executed by the Holder thereof or his attorney duly authorized in writing. No service charge shall be made for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

| **2** | **Assumptions** |

---

We have assumed:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the authenticity of all dates, signatures, seals, duty stamps and markings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) all authorisations specified above remain in full force and effect; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) all authorisations required for the Trustee to enter into the Indenture have been obtained and remain in full force and effect;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) there has been no breach or repudiation of, or waiver of any rights or obligations under the Indenture; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) the Bank and the Trustee remain ready, willing and able to perform their respective obligations under the Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) that the Indenture and the Notes have been executed and delivered and, in the case of the Notes, authenticated by duly authorised
signatories and delivered outside Australia in the form which we have examined and that all formalities required under the laws of the
place of execution of the Indenture have been complied with by the Bank and the Trustee;

---

| | |
|:---|:---|
| ![](tm2519266d1_ex5-2img001.jpg) | 1 July 2025 |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) that the obligations under the Indenture and the Notes are valid and binding obligations of the Bank and the Trustee under all relevant
laws (including the laws of the Relevant Jurisdictions except insofar as they affect the obligations of the Bank);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) that all the provisions in the Indenture have been, and will be, strictly complied with by the Bank and the Trustee;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) that the Notes have been, and will be, offered and sold in compliance with all relevant laws and in the manner contemplated by the
Registration Statement, the Prospectus and the Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the resolutions of the boards of directors referred to in paragraph 1(d) were properly passed (including that any meeting convened
was properly convened);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) all directors who participated and voted were entitled so to do;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) the directors and officers of the Bank granting the approvals referred to in paragraph 1(d) have properly performed their duties;
and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) all provisions relating to the declaration of directors' interests or the power of interested directors to vote were duly observed,

but there is nothing in the searches referred to in paragraph 3 or on the face of the extract of the authorisations referred to in paragraph 1(d) that would lead us to believe otherwise;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) that, if an obligation is to be performed in a jurisdiction outside Australia, its performance will not be contrary to an official
directive, impossible or illegal under the law of that jurisdiction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) that immediately following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) execution of the Indenture, the Bank was solvent; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) issue of the Notes, the Bank will be solvent;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) that the Trustee is not a related party of the Bank for the purposes of the Corporations Act 2001 of Australia ()"**Corporations Act** "); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m) that no person has been, or will be, engaged in conduct that is unconscionable, dishonest or misleading or deceptive or likely to
mislead or deceive (whether by act or omission) that might make any part of this opinion incorrect and there are no facts or circumstances
not evident from the face of the documents listed in paragraph 1 that might make any part of this opinion incorrect.

We have not taken any steps to verify these assumptions and assume that you do not know or suspect that any of these assumptions is incorrect.

---

| | |
|:---|:---|
| **3** | **Searches** |

---

We have examined and rely on:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) an extract of company information for the Bank obtained from the Australian Securities and Investments Commission ()"**ASIC** ")
in Sydney;

---

| | |
|:---|:---|
| ![](tm2519266d1_ex5-2img001.jpg) | 1 July 2025 |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the list of authorised deposit-taking institutions available from the website of the Australian Prudential Regulation Authority ()"**APRA** ");
and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) a search of the insolvency notices website maintained by ASIC to determine if any notices have been published in relation to the Bank,

in each case as at, respectively, approximately 8.07am local time on 1 July 2025.

These records are not necessarily complete or up to date. We have not examined documents filed by the Bank with ASIC or APRA nor have we made any other searches.

---

| | |
|:---|:---|
| **4** | **Opinion** |

---

On the foregoing basis and subject to the qualifications set out below, we are of the opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the Bank is incorporated and validly existing under the laws of Australia, is capable of suing and being sued in its corporate name
and is authorised to carry on banking business under the Banking Act 1959 of Australia ()"**Banking Act** ");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the Bank has the corporate power and authority to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) enter into the Indenture and observe its obligations under it; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) issue the Notes and observe its obligations under them;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) the Bank has taken all corporate action required on its part to authorise:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the filing of the Registration Statement, including the Prospectus, for the issue and sale of the Senior Debt Securities in an unlimited
amount; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the execution, delivery and observance of its obligations under the Indenture and the Indenture has been duly executed and delivered
by the Bank; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) insofar as the laws of the Relevant Jurisdictions are applicable, the Bank's obligations under the Indenture and the Notes are
legal, valid, binding and (subject to the terms of the Indenture) enforceable obligations of the Bank.

The expression "**enforceable**" means that the relevant obligations are of a type that the courts in the Relevant Jurisdictions enforce and does not mean that the obligations will necessarily be enforced in all circumstances in accordance with their terms.

---

| | |
|:---|:---|
| **5** | **Qualifications** |

---

This opinion is subject to the following qualifications:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the nature and enforcement of obligations may be affected by lapse of time, failure to take action or laws (including, without limitation,
laws relating to bankruptcy, insolvency, liquidation, receivership, administration, reorganisation, reconstruction, fraudulent transfer
or moratoria), certain equitable remedies, by general law doctrines or statutory relief in relation to matters such as fraud, misrepresentation,
mistake, duress, unconscionable conduct, unfair contracts legislation, frustration, estoppel, waiver, lapse of time, penalties, courts
retaining their ability to adjudicate, public policy or illegality or similar laws and defences generally affecting creditors' rights;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) an obligation and the rights of a creditor with respect to it may be affected by laws relating to insolvency (including, without limitation,
administration) and by a specific court order obtained under laws and defences generally affecting creditors' rights (including,
in the case of the Bank, sections 13A and 16 of the Banking Act and section 86 of the Reserve Bank Act 1959 of Australia as described
in the Prospectus);

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) the rights of a party to enforce its rights against the Bank may be limited or affected by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) breaches by that party of its obligations under the Indenture or the Notes, or misrepresentations made by it in, or in connection
with, the Indenture or the Notes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) conduct of that party which is unlawful;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) conduct of that party which gives rise to an estoppel or claim by the Bank; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) the Australian Code of Banking Practice if adopted by that party;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the availability of certain equitable remedies (including, without limitation, injunctions and specific performance) is at the discretion
of a court in the Relevant Jurisdictions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) an obligation to pay an amount may be unenforceable if the amount is held to constitute a penalty;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) a provision that a statement, opinion, determination or other matter is final and conclusive will not necessarily prevent judicial
enquiry into the merits of a claim by an aggrieved party;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) the laws of the Relevant Jurisdictions may require that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) parties act reasonably and in good faith in their dealings with each other, including, without limitation, in exercising rights, powers
or discretions or forming opinions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) discretions are exercised reasonably; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) opinions are based on good faith;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) a party entering into the Indenture may, in doing so, be acting, or later be held to have acted, in the capacity of a trustee under
an undocumented or partially documented constructive, implied or resulting trust which may have arisen as a consequence of that party's
conduct;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the question whether a provision of the Indenture which is invalid or unenforceable may be severed from other provisions is determined
at the discretion of a court in the Relevant Jurisdictions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) an indemnity for legal costs may be unenforceable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) we express no opinion as to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) any provision of a document that requires a person to do or not do something that is not clearly identified in the provision, or to
comply with another document;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) provisions precluding oral amendments or waivers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) Australian tax law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) whether the Bank is or will be complying with, or is or will be required to do or not to do anything by, the prudential standards,
prudential regulations or any directions made by APRA or under the Banking Act;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) the accuracy, completeness, correctness or suitability of any formula, equation or mathematical calculation set out in any document.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) any:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) proposal to introduce or change a law, or any pending change in law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) law which has been enacted and has not commenced, or if it has commenced, has not started to apply; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(C) pending judgment, or the possibility of an appeal from a judgment, of any court; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(D) the implications of any of them;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) laws in connection with sanctions, terrorism or money laundering may restrict or prohibit payments, transactions and dealings in certain
cases;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m) a court will not give effect to a currency indemnity, a choice of laws to govern a document or a submission to the jurisdiction of
certain courts if to do so would be contrary to public policy in the Relevant Jurisdictions. However, we consider it is unlikely that
a court in the Relevant Jurisdictions would reach such a conclusion in relation to New York law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(n) under laws relating to financial sector entities and related bodies (including the Banking Act and the Financial Sector (Transfer
and Restructure) Act 1999 of Australia), neither a contract to which the Bank is a party nor any other party to a contract to which the
Bank is a party may deny any obligations under that contract, accelerate any debt under that contract, close out any transaction relating
to that contract or enforce security under that contract on grounds including that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the Bank or a related body is subject to a direction by APRA;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) a Banking Act statutory manager (as defined in the Banking Act):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) is in control or is appointed to take control of the Bank's business or that of a related body; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) takes various actions in respect of any shares in the Bank or a related body; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) APRA issues a certificate to transfer compulsorily all or part of the business of the Bank or a related body or an act is done for
the purposes of such a transfer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(o) a payment made under mistake may be liable to restitution;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(p) we express no opinion on whether unfair contract terms legislation applies to a document (e.g. if it is a standard form document),
but note that if it does and the relevant document includes any provision which is an unfair term, among other things, that provision
may be void and civil penalties may apply; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(q) we express no opinion in respect of the Registration Statement or the Prospectus (and for the avoidance of doubt, including the documents
incorporated by reference in those documents) and we have not been, nor are we, responsible for verifying the accuracy of the facts, or
the reasonableness of any statements of opinion, contained in those documents, or that no material facts have been omitted from them.
Furthermore, we express no opinion as to whether the Registration Statement or the Prospectus contain all the information required in order for the issuance, offer
and sale of the Notes not to constitute misleading or deceptive conduct within the meaning of the Corporations Act or any analogous prohibited
conduct under any other law.
