PART I

Item 1. Business.
This Annual Report on Form 10-K relates to the
Series 1998-1G WST Trust (the "Trust") and the
Class A and Class B Mortgage Backed Floating Rate
Notes,Series 1998-1G (the "Notes") issued pursuant
to the Note Trust Deed dated as of June 10, 1998,
between Westpac Securities Administration Limited,
as Trustee (the "Issuer Trustee"); Westpac
Securitisation Management Pty Limited (the "Trust
Manager") as trust manager; and Citibank, London
Office, as Principal Paying Agent.  Capitalised
terms used in this Form 10-K and not defined have
the same meanings ascribed to such terms in the
Prospectus for the above-referenced Notes.
The only business of the Trust is the collection
and distribution of payments on the residential
mortgage loans in the manner described in the
Registration Statement on Form S-11 (File No.
333-46945) (the "Registration Statement").
Accordingly, there is no relevant information to
report in response to Item 101 of Regulation S-K.

Item 2. Properties
The Registrant and the Trust do not have any
physical properties. Accordingly, this item is not
applicable.

Item 3. Legal Proceedings.
The Trust Manager knows of no material legal
proceedings involving any Trust, the Trust
Manager, the Servicer or the Issuer Trustee
which were pending as of June 30, 2004, or as of
the date of this report.

Item 4. Submission of Matters to a Vote of
Security Holders
No votes or consents of Noteholders were
solicited during the fiscal year for any purpose.

PART II

Item 5. Market for Registrant's Common Equity
and Related Stockholder Matters
The Notes are not traded on any nationally
recognised exchange in the United States.  The
Notes are listed and exchanged on the London
Stock Exchange. Since the Trust pays no
dividends with respect to the Notes, the
information required by Item 201 of Regulation
S-K regarding dividends is inapplicable to
the Trust. See Exhibit 99.1 for information
with respect to distributions to
Noteholders.

Item 6. Selected Financial Data.
The regular quarterly Noteholders Reports, which
is required to be included with each quarterly
distribution of the Trusts assets to Noteholders,
sets forth for the prior quarter, as well as
cumulatively, all of the relevant financial
information required by the Note Trust Deed to be
reported to Noteholders.The Noteholders Reports
for the Payment Dates in October, 2003, January,
2004, April, 2004 and July, 2004 are incorporated
herein by reference and aggregated totals for the
fiscal year are incorporated herein as Exhibit
No. 99.1.The foregoing presents all relevant
financial information relating to the Trust.
Because of the limited business activity of
the Trust, the Selected Financial Data specified
in Item 301 of Regulation S-K would not provide
any meaningful additional information.

Item 7. Management's Discussion and Analysis of
Financial Condition and Results of Operation
Because of the limited business activity of the
Trust, the presentation of Managements Discussion
and Analysis of Financial Condition and Results of
Operations, as otherwise required by Item 303 of
Regulation S-K, would not be meaningful.  All
relevant information is contained in the
Noteholders Reports (filed under Current Reports
on Form 8-K) as described above.

Item 7A. Quantitative and Qualitative Disclosures
About Market Risk
Currency Exchange Control Risk
Interest and principal payments to holders of Notes
are paid in United States dollars ("U.S. dollars").
However payments on the Housing Loans are received
by the Issuer Trustee, in Australian dollars, in
Australia (the "Collections").  Pursuant to certain
swap agreements (the "Swap Agreements") the Issuer
Trustee is required to pay a portion of the
Collections to certain swap counterparties (the
"Currency Swap Providers") who in turn pays ("Swap
Currency Exchange"), at the direction of the Issuer
Trustee, U.S. dollars to the Noteholders, (the
"Currency Swap").  It is possible that in the
future Australia may impose exchange controls that
affect the availability of Australian dollar
payments for making payments under the Currency
Swap. The holders of the Notes will bear the risk
of the imposition of foreign exchange controls
by the Australian government that impact upon
the Issuer Trustee's ability to exchange the
Collections for U.S. dollars.  The Issuer Trustee
has no control over such risk, which will
generally be affected by economic and political
events in Australia.  If the Issuer Trustee does
not pay some or all of the amount in Australian
dollars which it is required to pay the Currency
Swap Provider under the Currency Swap, the
Currency Swap Provider is only required to pay
the U.S. dollar equivalent of the amounts it
actually receives.  In such event, it is unlikely
that the Trust would have sufficient U.S. dollars
to make the payments due on the Notes.

The Australian laws that control and regulate or
permit the control and regulation of a broad range
of payments and transactions involving non-residents
of Australia can be summarised as follows:

-Accounts of persons and entities identified by the
Minister for Foreign Affairs as being associated with
terrorism remain frozen, and transactions with these
persons and entities prohibited, under Regulation 6A
of the Charter of the United Nations (Terrorism and Dealings
with Assets) Regulations 2002, made under the Charter
of the United Nations Act 1945.  Details of these Regulations,
and the lists of persons and entities proscribed in terms of
the Regulations, are published in the Commonwealth
Government Gazette and are available on the website
of the Department of Foreign Affairs and Trade at
www.dfat.gov.au/icat/.

-The United Nations Security Council Resolution 1483
(2003) was implemented by way of Notice from the
Governor of the Reserve Bank of Australia pursuant to
the Banking (Foreign Exchange) Regulations 1959 (Cth),
and imposes a number of new measures intended to
facilitate Iraqs reconstruction and rehabilitation, including
obligations on UN Member States to freeze any financial
assets of the previous Iraqi regime and to make such
assets available for a Development Fund for Iraq.
Australias obligations under Resolution 1483 (2003)
were implemented under the Iraq (Reconstruction and
Repeal of Sanctions) Regulations, which commenced
on 29 May 2003.

-Transactions involving individuals associated with the
regime of former President of Yugoslavia Slobodan Milosevic
and certain ministers and senior officials of the Government
of Zimbabwe are prohibited without the specific approval
of the Reserve Bank of Australia under the Banking
(Foreign Exchange) Regulations 1959 (Cth). The Reserve
Bank of Australia publishes changes to prohibited parties
and variations in the restrictions on those parties from time
to time in the Commonwealth Government Gazette.

-Transactions over A$100,000 involving the Embassy
of the Federal Republic of Yugoslavia, the Consulate-General
of the Federal Republic of Yugoslavia or the National Bank
of Yugoslavia require prior approval from the Reserve Bank
of Australia.

Currency Exchange Risk.
Interest and principal on the Notes is payable in
U.S. dollars and the Trust's primary source for
funding its payments on the Notes is its
Collections on the Housing Loans, which will be
sourced in Australian dollars.  If the Currency
Swap Provider were to fail to perform under the
Currency Swap or were to be discharged from such
performance because of a default thereunder by the
Trust, the Trust might have to exchange its
Australian dollars for U.S. dollars at an exchange
rate that is less favourable to the Trust than when
the currency swap was entered into and might
therefore not have sufficient U.S. dollars to
make timely payments on the Notes, even though
the delinquency and loss experience on the Housing
Loans may be acceptable.

Item 8. Financial Statements and Supplementary Data
As discussed above, furnishing the financial
information required by Item 8 of Form 10-K would
not add any relevant information to that provided
by the foregoing statements.  Because the Notes are
essentially "pass-through" securities, the Trust
will have "income" only in the limited sense of
collecting payments on the residential mortgage
loans. The only material items of "expense" for the
Trust will be the amounts paid as servicing
compensation and potentially certain payments
relating to any credit enhancement facilities.
The Noteholders Reports (filed under Current
Reports on Form 8-K) provide complete information
on the amounts of the "income" and "expenses" of
the Trust.

Item 9. Changes in and Disagreements With
Accountants on Accounting and Financial
Disclosure
none.

PART III

Item 10. Directors and Executive Officers of the
Registrant
Since the Trust will not have any directors or
executive officers, this item is not applicable.

Item 11. Executive Compensation
Since the Trust will not have any directors or
executive officers, this item is not applicable.

Item 12. Security Ownership of Certain Beneficial
Owners and Management
The following table sets forth (i) the name and
address of each entity owning more than 5% of the
outstanding principal amount of the Class A Notes
or Class B Notes; (ii) the principal amount of
the Class of Notes owned by each, if known, and
(iii) the percent that the principal amount of the
Class of Notes owned represents of the outstanding
principal amount of the Class of Notes. The
information set forth in the table is based upon
information obtained by the Trust Manager from the
Trustee and from The Depository Trust Company as of
June 30, 2004. The Trust Manager is not aware of
any Schedules 13D or 13G filed with the Securities
and Exchange Commission in
respect of the Notes.

Exhibit 99.2

INDEPENDENT AUDITORS ANNUAL SERVICER
COMPLIANCE CERTIFICATE TO THE DIRECTORS
OF WESTPAC SECURITISATION MANAGEMENT PTY
LIMITED

SCOPE
We have reviewed Westpac Banking Corporation's
("WBC") and The Mortgage Company Pty Limited's
("TMC" and WBC and TMC each a "Servicer") activities
for the purpose of determining its compliance
with the servicing standards contained in the
agreement between:

-Westpac Banking Corporation as servicer, Westpac
 Securities Administration Limited as Trustee and
 Westpac Securitisation Management Pty Limited
 as Trust Manager dated 12 March 2002, as amended
 (the 2002 Servicing Agreement);

- Westpac Banking Corporation, Westpac Securities
  Administration Limited as Trustee and The
  Mortgage Company Pty Limited as servicer dated
  18 February 1997, as amended ( the "1997
  Servicing Agreement");

( each a "service agreement"), respectively
attached as Appendix 1A and Appendix IB,
in relation to the Series 1998-1G WST Trust,
Series 1999-1G WST Trust and Series 2002-1G WST
Trust  for the year ended 30 June, 2003,
in accordance with the statement by Division of
Corporation Finance of the Securities and
Exchange Commission dated 21 February 2003,
and our engagement letter dated 9 September 2004.

We have reviewed the servicing standards contained
in the Servicing Agreement to enable us to report
on whether those servicing standards are similar
to those contained in the Uniform Single
Attestation Program for Mortgage Bankers (USAP),
attached as Appendix 2, which establishes a minimum
servicing standard for the asset backed securities
market in the United States of America. No
equivalent of the USAP exists in Australia.

Management of the Servicer are responsible for
maintaining an effective internal control structure
including internal control policies and procedures
relating to the servicing of mortgage loans.
We have conducted an independent review of
the servicing standards included in Appendix 1,
in order to express a statement on the Servicers
compliance with them.

Our review of the servicing standards has been
conducted in accordance with Australian Auditing
Standards applicable to performance audits and
accordingly included such tests and procedures
as we considered necessary in the circumstances.
In conducting our review we have also had regard
to the guidance contained in the USAP.  These
procedures have been undertaken to enable us to
report on whether anything has come to our
attention to indicate that there has been
significant deficiencies in the Servicers
compliance with the servicing standards contained
in the Servicing Agreement for the year ended
30 June 2004.

Our review did not include an assessment of the
adequacy of the servicing standards themselves.

This statement has been prepared for the use of
Westpac Securitisation Management Pty Limited
as at 30 June 2004 in accordance with the
requirements of the statement by the Division
of Corporation Finance of the Securities and
Exchange Commission dated 21 February 2003
and the engagement letter dated 9 September 2004.
We disclaim any assumption of responsibility for
any reliance on this review statement, to any
person other than Westpac Securitisation
Management Pty Limited, Westpac Banking Corporation
and The Mortgage Company Pty Limited.

STATEMENT

Based on our review:

- Nothing has come to our attention to indicate
  That there has been any significant deficiencies
  in WBC's compliance with the servicing standards
  contained in the Servicing Agreement attached
  as Appendix 1A, in respect of the Series 2002-1G
  WST Trust for the year ended 30 June 2004; and

- Nothing has come to our attention to indicate
  that there has been any significant deficiencies
  in TMC's compliance with the servicing standards
  contained in the Servicing Agreement attached
  as Appendix 1B, in respect of the Series 1998-1G
  and the Series 1999-1G WST Trust.

- The servicing standards contained in Appendix 1
  are similar to the minimum servicing standards
  contained in the Uniform Single Attestation
  Program for Mortgage Brokers.

Westpac Securities Administration Limited
4th Floor, Endeavour House
50 Pitt Street
SYDNEY, NSW 2000
Attention: Mr Robert Hamilton

The Mortgage Company Pty Limited
Level 25
60 Martin Place
Sydney NSW 2000
Attention: Mr Andrew Carriline


Dear Sirs

Scope

We have audited the control procedures of The
Mortgage Company Pty Limited (the "Servicer")
in relation to its role as custodian as at
February 2004 in order to express an opinion
about their effectiveness based upon the
requirements of Clause 3.3 of the Westpac
Securitisation Trusts ("WST") Servicing
Agreement (the " Agreement").

The control procedures operating in relation to
the Series 1998-1 G WST Trust were audited as part
of the overall custody audit of the WST
Securitisation Program.

Unless otherwise defined, terms and phrases have the
same definition as those appearing in the WST
Transaction Documents.

The criteria required by Schedule 2 of the
Agreement are that:

1.   the custodial duties and responsibilities of
     the Servicer, as outlined in Section 3 of
     the Agreement, are met;

2.   the Relevant Documents are capable of
     identification,segregated by reference to the
     relevant Portfolio of Receivables and from
     other mortgage title documents held by the
     Servicer;

3.   the Relevant Documents may not be removed or
     tampered with except with appropriate
     authorisation; and

4.   an appropriate tracking system is in place such
     that the location of the Relevant Documents
     can be detected at any time.

5.   the Security Packets contain the Relevant
     Documents which the Series Terms indicate
     that they should ( including, as a minimum,The
     Receivable Security documents, and any
     certificate of Title if issued) based on a
     review of a sample of Security Packets.

The Servicer, under the delegation of the Trustee,
is responsible for maintaining an effective internal
control structure for the custodial operations of
Series 1998-1 G WST Trust. We have conducted an
independent audit of the control procedures in order
to express an opinion on them to the Trustee and
the Servicer.

Our audit of the control procedures has been
conducted in accordance with Australian Auditing
Standard AUS 810 "Special Purpose Reports on the
Effectiveness of Control Procedures" and
accordingly included such tests and procedures as
we considered necessary in the circumstances.
These procedures have been undertaken to form an
opinion whether in all material respects, the
control procedures in relation to the Servicer's
role as custodian were adequately designed so as
to achieve the criteria referred to above, and were
operating effectively at the time of our audit.

This report has been prepared for distribution to
the Trustee and the Servicer for the purpose of
monitoring the Servicer's custodial role. We
disclaim any assumption of responsibility
for any reliance on this report to any person
other than those mentioned, or for any purpose
other than that for which it was
prepared.

Inherent Limitations

Because of the inherent limitations of any internal
control structure it is possible that errors or
irregularities may occur and not be detected.
Further, the internal control structure, within
which the control procedures that we have audited
operate, has not been audited and no opinion
is expressed as to its effectiveness.

An audit is not designed to detect all weaknesses
in control procedures as it is not performed
continuously throughout the period and the tests
performed are on a sample basis.

Any projection of the evaluation of control
procedures to future periods is subject to the risk
that the procedures may become inadequate because
of changes in conditions, or that the degree of
compliance with them may deteriorate.

The audit opinion expressed in this report has been
formed on the above basis.

Findings

No errors were detected during our audit. On the
basis of these
findings and in accordance with schedule 2 of
the agreement, we grade the custodial performance
of the servicer as Good as defined in schedule 2
of the agreement i.e all control procedures
and accuracy of information in respect of Relevant
Documents completed without exception, other than
immaterial and occasional
variances.

Audit Opinion

In our opinion the Servicer maintained, in all
material respects, effective control procedures
in relation to the custodial operations of the
WST Securitisation Program, which includes
Series 1998-1G WST Trust, as at  February
2004 based on the criteria referred to above.
