Cleansing notice under section 708A(12H)(e) of the Corporations Act 2001 (Cth)
(“Act”) as inserted by ASIC Corporations (Regulatory Capital Securities) Instrument
2026/88 (“Instrument”)

1. Westpac has issued the Tier 2 Subordinated Notes on 20 August 2026. Offers
of the Tier 2 Subordinated Notes do not require disclosure to investors under
Part 6D.2 of the Act.
2. The terms and conditions of the Tier 2 Subordinated Notes (“Conditions”) are
set out on pages 58 to 115 of the Information Memorandum relating to
Westpac’s Debt Issuance Programme dated 19 May 2023 (“Information
Memorandum”), as supplemented by the Pricing Supplement in respect of the

dated 18 August 2026, the forms of which are attached to this notice as

Australia by the Australian Prudential Regulation Authority (“APRA”).
4. If APRA determines that Westpac is or would become non-viable, the Tier 2
Subordinated Notes may be:
(a) Converted into fully paid ordinary shares in the capital of Westpac; or

(b) immediately and irrevocably Written-off (and rights attaching to the Tier 2
Subordinated Notes terminated) if for any reason Conversion does not
occur within five ASX Business Days of APRA notifying Westpac of the
determination,
in accordance with the Conditions.
5. In order to enable ordinary shares in the capital of Westpac issued on
Conversion to be sold without disclosure under Chapter 6D of the Act, Westpac

This document has been authorised for release by Tim Hartin, Company Secretary.


NOT FOR DISTRIBUTION OR RELEASE IN THE UNITED STATES
This market announcement does not constitute an offer to sell or the solicitation of an
offer to buy any securities in the United States or any other jurisdiction. The securities
offered have not been and will not be registered under the U.S. Securities Act of 1933,
as amended, and may not be offered or sold in the United States or to, or for the
account or benefit of, U.S. persons absent registration or an applicable exemption from
registration.

SCHEDULE
A. Effect on Westpac of the offer of the Tier 2 Subordinated Notes
The issuance of the Tier 2 Subordinated Notes is expected to raise Tier 2 regulatory
capital to satisfy Westpac’s regulatory requirements and maintain the diversity of
Westpac’s sources and types of capital funding.
The proceeds from the issue of the Tier 2 Subordinated Notes will be used for general
corporate purposes. Those proceeds, less the costs of the issue, will be classified as
loan capital in the financial statements of Westpac. The issue of the Tier 2
Subordinated Notes will not have a material impact on Westpac’s financial position.
The proceeds of the issue, less the costs of the issue, are expected to increase
Westpac’s total capital ratio on a Level 2 basis by less than 0.4%.
B. Rights and liabilities attaching to the Tier 2 Subordinated Notes
The rights and liabilities attaching to the Tier 2 Subordinated Notes are set out in the
Conditions as supplemented by the relevant Pricing Supplement.
C. Effect on Westpac of the issue of the ordinary shares if the Tier 2
Subordinated Notes are required to be Converted
1

A key feature of APRA’s requirements for Tier 2 regulatory capital instruments is that
they absorb losses at the point of non-viability of the issuer. The Conditions include
provisions that require the Tier 2 Subordinated Notes to be Converted into ordinary
shares in the capital of Westpac or Written-off on the occurrence of a Non-Viability
Trigger Event. A Non-Viability Trigger Event will occur when APRA notifies Westpac in
writing that it believes that relevant non-viability circumstances (as described in the
definition of “Non-Viability Trigger Event” in the Conditions) subsist, which could occur at
any time.
If a Non-Viability Trigger Event occurs and Westpac Converts the Tier 2 Subordinated
Notes and issues ordinary shares to Holders (as required under the Conditions), the
effect of Conversion on Westpac would be to reduce loan capital by the principal
amount, less any unamortised costs of the issue, of the Tier 2 Subordinated Notes being
Converted and increase Westpac’s shareholders’ equity by a corresponding amount.
APRA has not provided extensive guidance as to how it would determine non‑viability.
Non-viability could be expected to include serious impairment of Westpac’s financial
position and concerns about its capital, funding or liquidity levels and/or insolvency.
APRA has indicated that non-viability is likely to arise prior to insolvency.

1
If, in accordance with the Conditions, Westpac is replaced by an Approved Successor as debtor of the Tier 2
Subordinated Notes and the issuer of ordinary shares, Tier 2 Subordinated Notes may be Converted into fully paid
ordinary shares in the capital of an Approved Successor in accordance with the Conditions. This notice also
enables ordinary shares in the capital of an Approved Successor which is a NOHC for the purposes of the Banking
Act 1959 (Cth) and the ultimate holding company of Westpac issued on Conversion to be sold without disclosure
under Chapter 6D of the Act. Refer to the Conditions and the Instrument for further information.

The number of ordinary shares issued on Conversion is variable, but is limited to the
Maximum Conversion Number. Limiting the number of ordinary shares which may be
issued to the Maximum Conversion Number means that it is likely that Holders will
receive a number of ordinary shares that have a market value that is significantly less
than the Outstanding Principal Amount of the Tier 2 Subordinated Notes.
The Maximum Conversion Number is calculated based on a VWAP set to reflect 20% of
the Issue Date VWAP. The Maximum Conversion Number may be adjusted to reflect a
consolidation, division or reclassification or pro rata bonus issue, of ordinary shares.
However, no adjustment will be made to it on account of other transactions which may
affect the price of ordinary shares, including for example, rights issues, returns of
capital, buy-backs or special dividends.
The Maximum Conversion Number is 1,355.7484 Westpac ordinary shares per Tier 2
Subordinated Note (with a nominal value of A$10,000), based on the Issue Date VWAP
of A$36.88. If Conversion of any Tier 2 Subordinated Notes does not occur for any
reason within five ASX Business Days after the occurrence of the Non-Viability Trigger
Event, the Tier 2 Subordinated Notes will be Written-off, and all corresponding rights
and claims of Holders under the Conditions (including with respect to payments of
interest, the repayment of the Outstanding Principal Amount and upon Conversion, the
receipt of ordinary shares) will be immediately and irrevocably written-off and
terminated, with effect on and from the Non-Viability Trigger Event Date in accordance
with the Conditions, and investors will lose all or some of their investment and will not
receive any compensation.
D. Rights and liabilities attaching to the ordinary shares in the capital of
Westpac
Westpac was registered on 23 August 2002 as a public company limited by shares
under the Act. Westpac’s constitution was most recently amended at the general
meeting held on 15 December 2021 (“Constitution”, as amended from time to time).
The ordinary shares in the capital of Westpac are admitted to trading on ASX. The
rights attaching to the ordinary shares in the capital of Westpac are set out in the Act
and the Constitution.
E. Additional information
Information about the Tier 2 Subordinated Notes is contained in the Information
Memorandum and the Pricing Supplements.
Westpac is a disclosing entity for the purposes of the Act and, as a result, is subject to
regular reporting and disclosure obligations under the Act and the ASX Listing Rules. In
addition, Westpac must notify ASX immediately (subject to certain exceptions) if it
becomes aware of information about Westpac that a reasonable person would expect to
have a material effect on the price or value of its listed securities, including ordinary
shares in the capital of Westpac.
Copies of documents lodged with the Australian Securities and Investments
Commission (“ASIC”) can be obtained from, or inspected at, an ASIC office and

Westpac’s ASX announcements may be viewed at https://www.asx.com.au.
Any person has the right to obtain copies of:
• Westpac’s half-yearly and annual financial reports; and
• any continuous disclosure notices given by Westpac after the lodgement of the

ANNEXURE A

Form of Pricing Supplement dated 18 August 2026 in respect of the issue of
A$250,000,000 Fixed Rate to Floating Rate Callable Subordinated Notes due 20
August 2036

NOTIFICATION UNDER SECTION 309B(1) OF THE SECURITIES AND FUTURES ACT 2001 OF
SINGAPORE, AS MODIFIED OR AMENDED FROM TIME TO TIME (THE “SFA”) – The Subordinated
Notes are “prescribed capital markets products” (as defined in the Securities and Futures (Capital
Markets Products) Regulations 2018) and Excluded Investment Products (as defined in MAS Notice
SFA 04-N12: Notice on the Sale of Investment Products and MAS Notice FAA-N16: Notice on
Recommendations on Investment Products).
PROHIBITION OF SALES TO EEA RETAIL INVESTORS – The Subordinated Notes are not intended
to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made
available to any retail investor in the European Economic Area (“EEA”). For these purposes, a retail
investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1)
of Directive 2014/65/EU (as amended, “MiFID II”); (ii) a customer within the meaning of Directive (EU)
2016/97, as amended (the “Insurance Distribution Directive”), where that customer would not qualify
as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor
as defined in Regulation (EU) 2017/1129 (the “Prospectus Regulation”). Consequently no key
information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs
Regulation”) for offering or selling the Subordinated Notes or otherwise making them available to retail
investors in the EEA has been prepared and therefore offering or selling the Subordinated Notes or
otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs
Regulation.
PROHIBITION OF SALES TO UK RETAIL INVESTORS – The Subordinated Notes are not intended
to be offered, sold, distributed or otherwise made available to and should not be offered, sold, distributed
or otherwise made available to any retail investor in the United Kingdom (“UK”). For these purposes, a
retail investor means a person who is either one (or both) of the following: (i) not a professional client,
as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law in
the UK by virtue of the European Union (Withdrawal) Act 2018; or (ii) not a qualified investor as defined
in paragraph 15 of Schedule 1 to the Public Offers and Admissions to Trading Regulations 2024.
Consequently, no disclosure document required by the FCA Product Disclosure Sourcebook (“DISC”)
for offering, selling or distributing the Subordinated Notes or otherwise making them available to retail
investors in the UK has been prepared and therefore offering, selling or distributing the Subordinated
Notes or otherwise making them available to any retail investor in the UK may be unlawful under DISC
and the Consumer Composite Investments (Designated Activities) Regulations 2024.

Schedule

The Information Memorandum is hereby supplemented with Westpac’s First Half 2026 Risk Factors
lodged with the ASX on 5 May 2026 and the following information, which shall be deemed to be
incorporated in, and to form part of, the Information Memorandum.

Save as otherwise defined herein, terms defined in the Information Memorandum have the same
meaning when used in this Schedule. To the extent there is any inconsistency between any statement
in this Schedule and any other statement in or incorporated by reference in the Information
Memorandum prior to the date of this Supplement, the statements in this Schedule will prevail.

Westpac 3Q26 update
Performance overview
1

Unaudited statutory net profit increased 3% to $1.8 billion. Net profit, excluding Notable Items
2
,
increased 2% to $1.8 billion and pre-provision profit rose 1%.
Continued operating momentum drove strong customer deposit and loan growth. Deposit growth of 2%
was driven by increases in transaction and term balances. Lending increased by 2%, reflecting broad-
based growth across the portfolio including 4% in Australian business lending, 3% in institutional lending
and 2% in Australian housing.
Net operating income increased 1% with a 2% rise in net interest income more than offsetting a 3%
decline in non-interest income.
Net Interest Margin (NIM) was stable at 1.89%. NIM comprised:
 Core NIM
3
of 1.78% was stable with benefits from the higher interest rate environment and
liquid assets offset by competitive pressures in lending, deposit mix and a higher proportion of
customers qualifying for saving bonus rates. Core NIM increased 1 basis point compared to
2Q26; and
 Treasury and Markets contribution of 11 basis points was steady, although up from 7 basis
points in 2Q26.

Operating expenses were well managed, increasing 1% due to salary and wage growth and investment
in the business. We continue to pursue productivity savings of more than $550 million in FY26.
Impairment charges were 10 basis points of average gross loans and included an increase in portfolio
overlays and an increase in the severity of the downside scenario.
Financial strength
4

The CET1 capital ratio was 12.1% as at 30 June 2026, well above the target ratio of 11.25%. The
reduction in CET1 reflects the payment of the 2026 interim dividend and growth in RWAs, which more
than offset earnings in the period.
The average liquidity coverage ratio was 134% and net stable funding ratio was 111%.
Sale of the RAMS mortgages portfolio on 1 August 2026 added 23 basis points to the CET1 capital
ratio and reduced the home loan portfolio by $15.4 billion.
Households and businesses continued to demonstrate resilience, with stressed exposures increasing
by 3 basis points to 1.19% of TCE and remaining at low levels.

This section compares the 3Q26 and 1H26 quarterly average periods for profit and loss items and 3Q26 movements for
balance sheet items, unless otherwise stated. The performance measures exclude the impact of Notable Items which are not
defined by Australian Accounting Standards. Statutory equivalent measures are provided in the Financial Summary below and
for definitions refer to pages 107-108 of Westpac’s 2026 Half Year US Disclosure Document.
2
Notable Items relates to economic hedges of term funding which will reverse over time and for 1H26 the impacts of the RAMS
sale.
3
Core net interest margin is calculated by excluding Notable Items and Treasury and Markets.
4
Movements in this section are for 3Q26 unless otherwise stated.

Credit impairment provisions were $5.3 billion as at 30 June 2026, with provisions above expected
losses of the base case economic scenario increasing to $2.0 billion. The ratio of CAP to credit RWA
decreased 2 basis points to 1.27% and total provisions to gross loans were stable at 58 basis points.

ANNEXURE B

Form of Pricing Supplement dated 18 August 2026 in respect of the issue of
A$1,250,000,000 Floating Rate Callable Subordinated Notes due 20 August 2036

NOTIFICATION UNDER SECTION 309B(1) OF THE SECURITIES AND FUTURES ACT 2001 OF
SINGAPORE, AS MODIFIED OR AMENDED FROM TIME TO TIME (THE “SFA”) – The Subordinated
Notes are “prescribed capital markets products” (as defined in the Securities and Futures (Capital
Markets Products) Regulations 2018) and Excluded Investment Products (as defined in MAS Notice
SFA 04-N12: Notice on the Sale of Investment Products and MAS Notice FAA-N16: Notice on
Recommendations on Investment Products).
PROHIBITION OF SALES TO EEA RETAIL INVESTORS – The Subordinated Notes are not intended
to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made
available to any retail investor in the European Economic Area (“EEA”). For these purposes, a retail
investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1)
of Directive 2014/65/EU (as amended, “MiFID II”); (ii) a customer within the meaning of Directive (EU)
2016/97, as amended (the “Insurance Distribution Directive”), where that customer would not qualify
as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor
as defined in Regulation (EU) 2017/1129 (the “Prospectus Regulation”). Consequently no key
information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs
Regulation”) for offering or selling the Subordinated Notes or otherwise making them available to retail
investors in the EEA has been prepared and therefore offering or selling the Subordinated Notes or
otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs
Regulation.
PROHIBITION OF SALES TO UK RETAIL INVESTORS – The Subordinated Notes are not intended
to be offered, sold, distributed or otherwise made available to and should not be offered, sold, distributed

as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law in
the UK by virtue of the European Union (Withdrawal) Act 2018; or (ii) not a qualified investor as defined
in paragraph 15 of Schedule 1 to the Public Offers and Admissions to Trading Regulations 2024.
Consequently, no disclosure document required by the FCA Product Disclosure Sourcebook (“DISC”)
for offering, selling or distributing the Subordinated Notes or otherwise making them available to retail
investors in the UK has been prepared and therefore offering, selling or distributing the Subordinated
Notes or otherwise making them available to any retail investor in the UK may be unlawful under DISC

Westpac 3Q26 update
Performance overview
1

Unaudited statutory net profit increased 3% to $1.8 billion. Net profit, excluding Notable Items
2
,
increased 2% to $1.8 billion and pre-provision profit rose 1%.
Continued operating momentum drove strong customer deposit and loan growth. Deposit growth of 2%
was driven by increases in transaction and term balances. Lending increased by 2%, reflecting broad-
based growth across the portfolio including 4% in Australian business lending, 3% in institutional lending
and 2% in Australian housing.
Net operating income increased 1% with a 2% rise in net interest income more than offsetting a 3%
decline in non-interest income.
Net Interest Margin (NIM) was stable at 1.89%. NIM comprised:
 Core NIM
3
of 1.78% was stable with benefits from the higher interest rate environment and
liquid assets offset by competitive pressures in lending, deposit mix and a higher proportion of
customers qualifying for saving bonus rates. Core NIM increased 1 basis point compared to
2Q26; and
 Treasury and Markets contribution of 11 basis points was steady, although up from 7 basis
points in 2Q26.

Operating expenses were well managed, increasing 1% due to salary and wage growth and investment
in the business. We continue to pursue productivity savings of more than $550 million in FY26.
Impairment charges were 10 basis points of average gross loans and included an increase in portfolio
overlays and an increase in the severity of the downside scenario.
Financial strength
4

The CET1 capital ratio was 12.1% as at 30 June 2026, well above the target ratio of 11.25%. The
reduction in CET1 reflects the payment of the 2026 interim dividend and growth in RWAs, which more
than offset earnings in the period.
The average liquidity coverage ratio was 134% and net stable funding ratio was 111%.
Sale of the RAMS mortgages portfolio on 1 August 2026 added 23 basis points to the CET1 capital
ratio and reduced the home loan portfolio by $15.4 billion.
Households and businesses continued to demonstrate resilience, with stressed exposures increasing
by 3 basis points to 1.19% of TCE and remaining at low levels.

This section compares the 3Q26 and 1H26 quarterly average periods for profit and loss items and 3Q26 movements for
balance sheet items, unless otherwise stated. The performance measures exclude the impact of Notable Items which are not
defined by Australian Accounting Standards. Statutory equivalent measures are provided in the Financial Summary below and
for definitions refer to pages 107-108 of Westpac’s 2026 Half Year US Disclosure Document.

Notable Items relates to economic hedges of term funding which will reverse over time and for 1H26 the impacts of the RAMS
sale.
3
Core net interest margin is calculated by excluding Notable Items and Treasury and Markets.
4
Movements in this section are for 3Q26 unless otherwise stated.

Credit impairment provisions were $5.3 billion as at 30 June 2026, with provisions above expected
losses of the base case economic scenario increasing to $2.0 billion. The ratio of CAP to credit RWA
decreased 2 basis points to 1.27% and total provisions to gross loans were stable at 58 basis points.
