In mobilising the capital to support customers’ climate transition and build resilience, defining what is “sustainable” is critical. Our new Sustainable Finance Framework details how we consider sustainable finance transactions and classify them as green, transition, social or sustainability. Under the Framework we have established 2030 targets of: • $55bn in lending1 • $40bn in bond facilitation2 We are currently assessing our prior lending and bond facilitation transactions and will report progress from FY24. Reporting under the Framework replaces previous disclosure on climate change solutions exposure.

APPENDIX 3: SUSTAINABILITY – FOOTNOTES Sustainability and climate-related opportunities 1. Our lending target will be the total committed exposure (TCE) or balance (applicable for residential mortgages) at 30 Sept-30. Reported progress against the target will be TCE or balance at a point-in-time based on transactions completed during the year, along with previous transactions assessed as sustainable under the Framework. The target requires continued growth in TCE or balance, including replacing balances paid down. 2. Our bond facilitation target and progress will be measured as the cumulative sum of our proportionate share of qualifying bond issuances facilitated from 1 Oct-21. 3. When structuring or participating in labelled sustainable finance transactions, Westpac was guided by national sustainable finance taxonomies, and global sustainable finance market standards, principles and guidance commonly used to label or categorise loans and bonds as green, social, sustainability or sustainability-linked (such as, principles and guidance issued by the Loan Market Association, International Capital Markets Association and/or the Climate Bond Initiative). 4. Excludes Westpac Institutional Bank in New Zealand. 5. Unique customers are identified as individual legal entities. The increase in the number of unique customers and total committed exposure is predominantly due to the 2023 launch of two new products in New Zealand, the Sustainable Business Loan and the Sustainable Farm Loan.

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 APPENDIX 4: DEFINITIONS – CREDIT QUALITY 116 Westpac Group 2024 Interim Results Presentation & Investor Discussion Pack APPENDIX

SEGMENTS Consumer Consumer provides banking products and services, including mortgages, credit cards, personal loans, and savings and deposit products to Australian retail customers Business and Wealth Business and Wealth serves the banking and wealth needs of Australian customers, including small business, Agribusiness and Commercial businesses WIB Westpac Institutional Bank (WIB) provides a broad range of financial products and services to corporate, institutional and government customers Westpac NZ Westpac New Zealand provides banking, wealth and insurance products and services for consumer, business and institutional customers in New Zealand EARNINGS DRIVERS Average interest-earning assets (AIEA) The average balance of assets held by the Group that generate interest income. Where possible, daily balances are used to calculate the average balance Group 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 or 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 4: DEFINITIONS – SEGMENTS, EARNINGS DRIVERS, CAPITAL AND LIQUIDITY 117 Westpac Group 2024 Interim Results Presentation & Investor Discussion Pack APPENDIX

All amounts are in Australian dollars unless otherwise indicated. The financial information in this presentation is presented in accordance Australian Accounting Standards (AAS) and is also compliant with International Financial Reporting Standards. In assessing Westpac’s performance and that of our operating segments we use a number of financial measures, including amounts, measures and ratios that are presented on a non-AAS basis. Non-AAS financial measures and ratios do not have standardised meanings under AAS. As such they are unlikely to be directly comparable to similar measures presented by other companies and should not be viewed in isolation from, or as a substitute for, the AAS results.

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 intent, belief or current expectations with respect to our business and operations, macro and micro economic and market conditions, results of operations and financial condition, capital adequacy 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’, 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 expectations or beliefs concerning future developments and their potential effect upon Westpac. 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 section titled ‘Risk factors' in our 2024 Interim Financial Results for the six months ended 31 March 2024 available at www.westpac.com.au.

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.
