The changes will impact the CET1 minimum, CET1 buffers and Tier 2 requirements. There is no overall increase in total capital requirements for banks • APRA has also proposed changes to the leverage ratio, large exposures and related entity limits, which will see these calculations based on CET1 capital rather than Tier 1 capital Expected in 2027 APS116 – Market Risk • APRA is yet to commence consultation on Fundamental Review of the Trading Book Review decision expected Dec 2025 RBNZ Capital Review • In August 2025, the RBNZ released a consultation paper outlining potential amendments to the prudential framework and is seeking feedback from deposit takers (including WNZL). Proposed changes will impact standardised risk weightings, CET1 minimum, CET1 buffers, Tier 2 requirements and Total Capital Requirements • The RBNZ is expected to make its final decisions in December 2025 with the implementation timeline to be announced in the first quarter of the 2026 calendar year This page contains 'forward looking statements'.

The following details the adjustments and how Westpac's APRA CET1 capital ratio aligns to an internationally comparable ratio: 1 Internationally comparable methodology references the ABA study on the comparability of APRA's capital framework and finalised reform released on 10 March 2023. 2 Internal ratings-based approach (IRB). CAPITAL, FUNDING AND LIQUIDITY Westpac's CET1 capital ratio (APRA basis) 12.5 Equity investments Balances below prescribed threshold are risk weighted, compared to a 100% CET1 deduction under APRA's requirements 0.0 Deferred tax assets Balances below prescribed threshold are risk weighted, compared to a 100% CET1 deduction under APRA's requirements 0.6 Capitalised expenses APRA requires these items to be deducted from CET1. The BCBS only requires exposures classified as intangible assets under relevant accounting standards to be deducted from CET1 0.6 Interest rate risk in the banking book (IRRBB) APRA requires capital to be held for IRRBB. The BCBS does not have a Pillar 1 capital requirement for IRRBB 1.4 RWA scaling factor APRA applies a scaling factor to all Advanced IRB2 credit RWAs. The BCBS does not apply this scalar 0.9 Property finance APRA applies an additional scaling factor to property finance RWA. The BCBS does not apply this scalar 0.5 Residential mortgages APRA applies scaling factors to mortgage RWAs for higher risk segments such as interest only and investor mortgages and applies a standardised risk weight to certain mortgages. The BCBS does not apply this treatment 1.6 Non-retail Loss Given Default (LGD) Non-retail LGD's under the Foundation IRB (F-IRB) and Advanced IRB approaches differ from the BCBS (0.3) New Zealand APRA requires New Zealand RWAs to be largely calculated in accordance with the RBNZ rules. The RBNZ rules are more conservative than BCBS 0.5 Internationally comparable CET1 capital ratio 18.3 Internationally comparable Tier 1 capital ratio 20.8 Internationally comparable total regulatory capital ratio 30.3 |

Stressed exposures Watchlist and substandard, non-performing not impaired, and impaired exposures Total committed exposures (TCE) Represents the sum of the committed portion of direct lending (including funds placement overall and deposits placed), contingent and pre-settlement risk plus the committed portion of secondary market trading and underwriting risk Watchlist and substandard Loan facilities where customers are experiencing operating weakness and financial difficulty but are not expected to incur loss of interest or principal APPENDIX 2: DEFINITIONS – CREDIT QUALITY 120 Westpac Group 2025 Full Year Results Presentation & Investor Discussion Pack APPENDIX <90 days past due Includes facilities less than 90 days past due and those credit exposures, that are in default, but where it is expected that the full value of principal and accrued interest can be collected, generally by reference to the value of security held 90+ days past due Includes facilities 90 days or more past due, and those credit exposures that are in default, but where it is expected that the full value of principal and accrued interest can be collected, generally by reference to the value of security held Provision for expected credit losses Expected credit losses (ECL) are a probability-weighted estimate of the cash shortfalls expected to result from defaults over the relevant time frame. They are determined by evaluating a range of possible outcomes and taking into account the time value of money, past events, current conditions and forecasts of future economic conditions Collectively assessed provisions (CAP) CAP for ECL under AASB 9 represent the ECL which is collectively assessed in pools of similar assets with similar risk characteristics. This incorporates forward looking information and does not require an actual loss event to have occurred for an impairment provision to be recognised Individually assessed provisions (IAP) Provisions raised for losses on loans that are known to be impaired and are assessed on an individual basis. The estimated losses on these impaired loans is based on expected future cash flows discounted to their present value and, as this discount unwinds, interest will be recognised in the income statement Stage 1: 12 months ECL – performing For financial assets where there has been no significant increase in credit risk since origination a provision for 12 months ECL is recognised. Interest revenue is calculated on the gross carrying amount of the financial asset Stage 2: Lifetime ECL – performing For financial assets where there has been a significant increase in credit risk since origination but where the asset is still performing a provision for lifetime ECL is recognised. Interest revenue is calculated on the gross carrying amount of the financial asset Stage 3 Lifetime ECL – non-performing For financial assets that are non-performing a provision for lifetime ECL is recognised. Interest revenue is calculated on the carrying amount net of the provision for ECL rather than the gross carrying amount |

Where possible, daily balances are used to calculate the average balance Net interest margin Calculated by dividing net interest income by average interest-earning assets (annualised where applicable) Core net interest margin Calculated by dividing net interest income excluding Notable Items and Treasury & Markets by average interest-earning assets (annualised where applicable) Pre-provision profit Net operating income less operating expenses NCI Non-controlling interests Full-time equivalent employees (FTE) A calculation based on the number of hours worked by full and part-time employees as part of their normal duties. For example, the full-time equivalent of one FTE is 76 hours paid work per fortnight Capital and liquidity Capital ratios As defined by APRA (unless stated otherwise) Committed liquidity facility (CLF) The RBA makes available to Australian Authorised Deposit-taking Institutions (ADIs) a CLF that, subject to qualifying conditions, can be accessed to meet LCR requirements under APS210 Liquidity. APRA announced in September 2021 that ADIs subject to the LCR should reduce their CLF usage to zero by 1 January 2023 High quality liquid assets (HQLA) Assets which meet APRA's criteria for inclusion as HQLA in the numerator of the LCR Internationally comparable ratios Internationally comparable regulatory capital ratios are Westpac's estimated ratios after adjusting the capital ratios determined under APRA Basel III regulations for various items. Analysis aligns with the APRA study titled "International capital comparison study" dated 13 July 2015 Leverage ratio As defined by APRA (unless stated otherwise). Tier 1 capital divided by 'exposure measure' and expressed as a percentage. 'Exposure measure' is the sum of on-balance sheet exposures, derivative exposures, securities financing transaction exposures and other off-balance sheet exposures Liquidity coverage ratio (LCR) An APRA requirement to maintain an adequate level of unencumbered high quality liquid assets, to meet liquidity needs for a 30 calendar day period under an APRA-defined severe stress scenario. Absent a situation of financial stress, the value of the LCR must not be less than 100%. LCR is calculated as the percentage ratio of stock of HQLA and CLF over the total net cash out-flows in a modelled 30 day defined stressed scenario Net stable funding ratio (NSFR) The NSFR is defined as the ratio of the amount of available stable funding (ASF) to the amount of required stable funding (RSF) defined by APRA. The amount of ASF is the portion of an ADI's capital and liabilities expected to be a reliable source of funds over a one year time horizon. The amount of RSF is a function of the liquidity characteristics and residual maturities of an ADI's assets and off-balance sheet activities. ADI's must maintain an NSFR of at least 100% Risk weighted assets (RWA) Assets (both on and off-balance sheet) are risk weighted according to each asset's inherent potential for default and what the likely losses would be in case of default. In the case of non-asset-backed risks (ie. market and operational risk), RWA is determined by multiplying the capital requirements for those risks by 12.5 APPENDIX 2: DEFINITIONS – SEGMENTS, EARNINGS DRIVERS, CAPITAL AND LIQUIDITY 121 Westpac Group 2025 Full Year Results Presentation & Investor Discussion Pack |

The information is supplied in summary form and is therefore not necessarily complete. It is not intended that it be relied upon as advice to investors or potential investors, who should consider seeking independent professional advice depending upon their specific investment objectives, financial situation or particular needs. The material contained in this presentation may include information derived from publicly available sources that have not been independently verified. No representation or warranty is made as to the accuracy, completeness or reliability of the information. All amounts are in Australian dollars unless otherwise indicated. This presentation contains statements that constitute "forward-looking statements" within the meaning of Section 21E of the US Securities Exchange Act of 1934. Forward-looking statements are statements that are not historical facts. Forward-looking statements appear in a number of places in this presentation and include statements regarding our current intent, belief or expectations with respect to our business and operations, macro and micro economic and market conditions, results of operations and financial condition, capital adequacy, liquidity and risk management, including, without limitation, future loan loss provisions and financial support to certain borrowers, forecasted economic indicators and performance metric outcomes, indicative drivers, climate- and other sustainability-related statements, commitments, targets, projections and metrics, and other estimated and proxy data. We use words such as 'will', 'may', 'expect', 'intend', 'seek', 'would', 'should', 'could', 'continue', 'plan', 'estimate', 'anticipate', 'believe', 'probability', 'indicative', 'risk', 'aim', 'outlook', 'forecast', 'f'cast', 'f', 'assumption', 'projection', 'target', 'goal', 'guidance', 'ambition', 'objective' or other similar words to identify forward-looking statements, or otherwise identify forward-looking statements. These forward-looking statements reflect our current views on future events and are subject to change, certain known and unknown risks, uncertainties and assumptions and other factors which are, in many instances, beyond our control (and the control of our officers, employees, agents and advisors), and have been made based on management's and/or the board's current expectations or beliefs concerning future developments and their potential effect upon us. Forward-looking statements may also be made, verbally or in writing, by members of Westpac's management or Board in connection with this presentation. Such statements are subject to the same limitations, uncertainties, assumptions and disclaimers set out in this presentation. There can be no assurance that future developments or performance will align with our expectations or that the effect of future developments on us will be those anticipated. Actual results could differ materially from those we expect or which are expressed or implied in forward-looking statements, depending on various factors including, but not limited to, those described in the sections titled 'Our Operating Environment' and 'Risk Management' in our 2025 Annual Report as well as the 2025 Risk Factors document available at www.westpac.com.au. When relying on forward-looking statements to make decisions with respect to us, investors and others should carefully consider such factors and other uncertainties and events. Except as required by law, we assume no obligation to revise or update any forward-looking statements contained in this presentation, whether from new information, future events, conditions or otherwise, after the date of this presentation. We also make statements about our processes and policies (including what they are designed to do) as well as the availability of our systems or product features. Systems, processes and product features can be subject to disruption, and may not always work as intended, so these statements are limited by the factors described in the section titled 'Risk Management' in our 2025 Annual Report as well as the 2025 Risk Factors. Further important information regarding climate change and sustainability-related statements This presentation contains forward-looking statements and other representations relating to environment, social and governance (ESG) topics, including but not limited to climate change, net-zero, climate resilience, natural capital, emissions intensity, human rights and other sustainability related statements, commitments, targets, projections, scenarios, risk and opportunity assessments, pathways, forecasts, estimated projections and other proxy data. These are subject to known and unknown risks, and there are significant uncertainties, limitations, risks and assumptions in the metrics and modelling on which these statements rely. In particular, the metrics, methodologies and data relating to climate and sustainability are rapidly evolving and maturing, including variations in approaches and common standards in estimating and calculating emissions, and uncertainty around future climate and sustainability related policy and legislation. There are inherent limits in the current scientific understanding of climate change and its impacts. Some material contained in this presentation may include information including, without limitation, methodologies, modelling, scenarios, reports, benchmarks, tools and data, derived from publicly available or government or industry sources that have not been independently verified. No representation or warranty is made as to the accuracy, completeness or reliability of such information. There is a risk that the estimates, judgements, assumptions, views, models, scenarios or projections used by Westpac may turn out to be incorrect. These risks may cause actual outcomes, including the ability to meet commitments and targets, to differ materially from those expressed or implied in this presentation. The climate and sustainability related forward-looking statements made in this presentation are not guarantees or predictions of future performance and Westpac gives no representation, warranty or assurance (including as to the quality, accuracy or completeness of these statements), nor guarantee that the occurrence of the events expressed or implied in any forward-looking statement will occur. There are usually differences between forecast and actual results because events and actual circumstances frequently do not occur as forecast and these differences may be material. Westpac will continue to review and develop its approach to ESG as this subject area matures DISCLAIMER |
