Rules 4.7.3 and 4.10.3 ASX Listing Rules Appendix 4G (current at 17/7/2020) Page 1 Appendix 4G Key to Disclosures Corporate Governance Council Principles and Recommendations Name of entity WESTPAC BANKING CORPORATION ABN/ARBN Financial year ended: 33 007 457 141 30 September 2022 Our corporate governance statement 1 for the period above can be found at: 2 ☐ These pages of our annual report: ☒ This URL on our website: www.westpac.com.au/about-westpac/westpac-group/corporate- governance/corporate-governance-overview/ The Corporate Governance Statement is accurate and up to date as at 6 November 2022 and has been approved by the board. The annexure includes a key to where our corporate governance disclosures can be located. 3 Date: 7 November 2022 Name of authorised officer authorising lodgement: Tim Hartin, Company Secretary 1 “Corporate governance statement” is defined in Listing Rule 19.12 to mean the statement referred to in Listing Rule 4.10.3 which discloses the extent to which an entity has followed the recommendations set by the ASX Corporate Governance Council during a particular reporting period. Listing Rule 4.10.3 requires an entity that is included in the official list as an ASX Listing to include in its annual report either a corporate governance statement that meets the requirements of that rule or the URL of the page on its website where such a statement is located. The corporate governance statement must disclose the extent to which the entity has followed the recommendations set by the ASX Corporate Governance Council during the reporting period. If the entity has not followed a recommendation for any part of the reporting period, its corporate governance statement must separately identify that recommendation and the period during which it was not followed and state its reasons for not following the recommendation and what (if any) alternative governance practices it adopted in lieu of the recommendation during that period. Under Listing Rule 4.7.4, if an entity chooses to include its corporate governance statement on its website rather than in its annual report, it must lodge a copy of the corporate governance statement with ASX at the same time as it lodges its annual report with ASX. The corporate governance statement must be current as at the effective date specified in that statement for the purposes of Listing Rule 4.10.3. Under Listing Rule 4.7.3, an entity must also lodge with ASX a completed Appendix 4G at the same time as it lodges its annual report with ASX. The Appendix 4G serves a dual purpose. It acts as a key designed to assist readers to locate the governance disclosures made by a listed entity under Listing Rule 4.10.3 and under the ASX Corporate Governance Council’s recommendations. It also acts as a verification tool for listed entities to confirm that they have met the disclosure requirements of Listing Rule 4.10.3. The Appendix 4G is not a substitute for, and is not to be confused with, the entity's corporate governance statement. They serve different purposes and an entity must produce each of them separately. 2 Tick whichever option is correct and then complete the page number(s) of the annual report, or the URL of the web page, where your corporate governance statement can be found. You can, if you wish, delete the option which is not applicable. 3 Throughout this form, where you are given two or more options to select, you can, if you wish, delete any option which is not applicable and just retain the option that is applicable. If you select an option that includes “OR” at the end of the selection and you delete the other options, you can also, if you wish, delete the “OR” at the end of the selection. See notes 4 and 5 below for further instructions on how to complete this form.

The framework establishes the roles and responsibilities of Westpac’s Board, management team, employees and suppliers. It also establishes the systems, policies and processes for monitoring and evaluating Board and management performance, and the practices for corporate reporting, disclosure, remuneration, risk management and engagement of security holders.Our approach to corporate governance is based on a set of values and behaviours that underpin our day-to-day activities, and are designed to promote transparency, fair dealing, and the protection of stakeholder interests, including our customers, our shareholders, our employees and our community. It includes aspiring to the highest standards of corporate governance, which Westpac sees as fundamental to the sustainability of our business and our performance.As Westpac’s principal listing is on the ASX, we have followed the ASX Corporate Governance Principles and Recommendations (fourth edition) (ASXCGC Recommendations) published by the ASX Limited’s Corporate Governance Council (ASXCGC) throughout the year.

Board skills, experience and attributesWestpac seeks to maintain a Board of Directors with a broad range of relevant financial and other skills, knowledge, and experience necessary to guide the business of the Group. The Board uses a skills matrix to illustrate the key skills and experience the Westpac Board is seeking to achieve in its membership collectively and the number of Directors with each skill and experience. The skills matrix also assists in identifying focus areas for the continuing education and professional development of Directors. For example, in FY22, these focus areas included digitisation, decentralised finance, automation, privacy risk and climate change (amongst others). The skills matrix also assists in identifying areas where it may be desirable for specialist external expertise to be retained to supplement the Board’s skills and experience.As part of the regular review of the skills matrix, the matrix was amended this year, including through the addition of a new standalone skill category – ‘Environment & Social’. The skills matrix is set out in Figure 1.Figure 1 – Board skills, experience and attributes as at 30 September 2022In addition to the skills outlined above, the Westpac Board seeks to ensure that it operates as a cohesive team, bringing together a range of perspectives to guide the company and oversee management. The Westpac Board also expects its members to be committed to achieving our Purpose and upholding our Values.

Board diversityA diverse group of skilled Directors make us a stronger organisation that makes better decisions. In relation to gender diversity, for 2022, the Board Nominations & Governance Committee has approved an objective of 40% women, 40% men and 20% any gender for the composition of the Westpac Board.As Westpac has met its 2022 objective for Board gender diversity, the focus is on maintaining alignment with this objective, noting that our performance against it will vary at any given time depending on the timing of Board renewal and Board composition changes.The Board gender diversity as at 30 September 2022 is set out below. Number of female Directors on the Board (4 out of 10) 40%FEMALE DIRECTORSIndependenceAll of our Non-executive Directors satisfy our criteria for independence, which aligns with the guidance provided in the ASXCGC Recommendations.The Board assesses the independence of our Non- executive Directors on appointment and annually. Each Non-executive Director provides an annual attestation of their interests and independence. Directors are considered to be independent if they are independent of management and free from any business or other relationship that could materially interfere with, or could reasonably be perceived to materially interfere with: —the exercise of their unfettered and independent judgement; and —their ability to act in the best interests of Westpac as a whole rather than the interests of another party.Materiality is assessed on a case-by-case basis by reference to each Non-executive Director’s individual circumstances rather than by applying general materiality thresholds.Each Non-executive Director is required to disclose any business or other relationship that they have directly, or as a partner, shareholder or officer of a company or other entity that has an interest or a business or other relationship with Westpac or a Group entity. The Board considers information about any such interests or relationships, including any related financial or other details, when it assesses the Non-executive Director’s independence.Appointment of DirectorsThe Board Nominations & Governance Committee considers and makes recommendations to the Board on candidates for appointment as Directors. Such recommendations pay particular attention to: —the mix of skills, experience, expertise, diversity, independence, and other qualities of existing Directors; and —how the candidate’s attributes will balance and complement those skills and qualities and address any potential skills gaps in relation to the current and future composition of the Board.Subject to the Constitution and ASX Listing Rules, the Board may appoint a Director, either to fill a casual vacancy or as an addition to the existing Directors. Except for the CEO, a Director appointed by the Board holds office only until the close of the next annual general meeting (AGM) but is eligible for election by shareholders at that meeting.Our Constitution states that a Director (except for the CEO) must not hold office (without re-election) past the third AGM or for three years, whichever is longer. Retiring Directors hold office until the conclusion of the meeting at which they retire but are eligible for re-election at that meeting.Our Constitution also provides that at least one Director must stand for election or re-election at each AGM. This requirement could be satisfied by a person standing for election as a new Director; a Director who has been appointed to fill a casual vacancy seeking election; or a Director seeking re-election because of the tenure limitation (referred to in the paragraph above). If there are no such Directors required to stand for election or re-election at the AGM, and no Director volunteers to stand for re-election, the Director who has served the longest in office since their last election or re-election must retire and stand for re-election. The CEO is not required to stand for re-election.Prior to a Director’s appointment or consideration for election or re-election by shareholders, the Board conducts due diligence and considers the results of the Board performance evaluation conducted during the year. Where a Director is seeking election or re-election, Westpac provides shareholders with all material information relevant to a decision on whether or not to elect or re-elect a Director.New Directors receive an induction pack and letter of appointment setting out the expectations of the role, conditions of appointment including the expected term of appointment, and remuneration. This letter aligns to the ASXCGC Recommendations. All new Directors participate in an induction program to familiarise themselves with our business and strategy, culture and values and any current issues before the Board. The induction program includes substantial review of key documents and meetings with a range of representatives from the organisation, and includes meetings with the Chairman, the CEO, the Board Committee Chairs and each Group Executive. WESTPAC GROUP 2022 CORPORATE GOVERNANCE STATEMENT 6

The Westpac Board Renewal Policy limits the tenure of office that any Non-executive Directors other than the Chairman may serve to nine years, from the date of first election by shareholders. The maximum tenure for the Chairman is 12 years (which includes any term served as a Director prior to being elected as Chairman), from the date of first election by shareholders. The Board, on an exceptional basis, may extend the maximum terms specified above where it considers it would benefit the Group, on an annual basis, with the Director required to stand for re-election annually.The average Board tenure as at 30 September 2022 is set out below. The length of service of each Director is set out in Section 1 of the Directors’ report in our 2022 Annual Report. Average Board tenure 0-3 years 60% 3-6 years 30% 6-9 years 10% 3.4 yearsAVERAGE BOARD TENURE Conflicts of interest All Directors are required to disclose to the Board any actual, potential or apparent conflicts of interest upon appointment and are required to keep these disclosures up to date.Any Director with a material personal interest in a matter being considered by the Board must declare their interest and may not be present during any related boardroom discussions nor vote on the matter unless the Board resolves otherwise.Continuing educationDirectors undertake continuing education and training to develop and maintain the skills and knowledge needed to perform their role effectively, including by participating in workshops held throughout the year, attending relevant site visits, and undertaking relevant external education.These activities are planned each year and are included in the Board’s/Board Committees’ calendars. In addition, the Board and Board Committees consider whether additional education and professional development opportunities should be offered as part of the annual Board Effectiveness Review.Access to informationAll Directors have unrestricted access to company records and information required to perform their duties, and receive regular detailed financial and operational reports from senior management. Each Director also enters into an access and indemnity agreement, which among other things, provides for access to documents for up to seven years after their retirement as a Director.The Chairman and other Non-executive Directors regularly consult with the CEO, CFO and other senior executives, and may consult with, and request additional information from, any of our employees.Access to adviceAll Directors have access to advice from senior internal legal advisors including the Group General Counsel.The Board collectively, and all Directors individually, can also seek independent professional advice, at our expense, to help them carry out their responsibilities. While the Chairman’s prior approval is needed, it may not be unreasonably withheld.Remuneration frameworkInformation about our remuneration framework, including policies and practices regarding the remuneration of Non-executive Directors, the CEO and other senior executives, is included in the Remuneration Report in the Directors’ report (which is located in our 2022 Annual Report). The Remuneration Report also includes details of Westpac’s hedging policy, which prohibits participants in equity plans from entering into transactions that mitigate the risk associated with the equity award.7 WESTPAC GROUP 2022 CORPORATE GOVERNANCE STATEMENT INTRODUCTIONTHE BOARDOPERATION OF THE BOARDDIVERSITY, ETHICAL DECISION MAKING, KEY POLICIES & SUSTAINABILITYRISKFINANCIAL REPORTING AND DISCLOSURE

Key policies We have a number of key policies to manage our regulatory compliance and human resource requirements. We are also subject to a range of external industry codes, such as the Banking Code of Practice and the ePayments Code.Code of Ethics for Senior Finance OfficersOur Code of Accounting Practice and Financial Reporting (COAPFR) complements our Code of Conduct. It is designed to assist our CEO, CFO and other principal financial officers to apply the highest ethical standards to their duties and responsibilities with respect to accounting and financial reporting. The COAPFR requires those officers to: —act honestly and ethically, particularly with respect to conflicts of interest; —provide full, fair, accurate and timely disclosure in reporting and other communications; —comply with applicable laws, rules and regulations; —promptly report violations of the COAPFR; and —be accountable for adherence to the COAPFR.The COAPFR is available on our website at www.westpac.com.au/about-westpac/westpac-group/ corporate-governance/principles-policies/.Delegated authorityThe Delegated Authority Policy Framework outlines the principles Westpac has adopted to govern decision making within the Westpac Group, including channels of escalation and reporting to the Board.The scope of, and limitations to, authority delegated by the Board to the CEO and through the CEO to other Group Executives, is articulated in formal delegation instruments and covers areas such as expenditure, funding and securitisation, and lending. These delegations have been implemented with a view to balancing effective oversight with appropriate empowerment and accountability of management.Any matters or transactions outside the delegations of authority given to management are required to be referred to the Board or relevant Board Committee for approval.Securities tradingWestpac’s Group Securities Trading Policy prohibits Directors, employees, secondees and contractors from dealing in any securities and other financial products that they possess inside information on. They are also prohibited from passing on inside information to others who may use that information to trade in securities or from procuring others to trade.In addition, Directors and any employees, secondees or contractors (and their ‘associates’) who, because of their seniority or the nature of their position, may have access to material non-public information about Westpac (known as Prescribed Employees) are subject to further restrictions, including prohibitions on trading prior to and immediately following annual and half year results announcements. The Westpac Group Securities Trading Policy is available in the Corporate Governance section of our website at www.westpac.com.au/about-westpac/westpac-group/corporate-governance/principles- policies/.Concern reporting and whistleblower protectionThe Westpac Group Speaking Up Policy encourages our employees, contractors, secondees, former employees, brokers, service providers and suppliers to raise any concerns about our activities or behaviours that may be unlawful or unethical. Our senior management are committed to supporting anyone reporting wrongdoing, and protecting their dignity, wellbeing, career and reputation. Westpac does not tolerate detrimental conduct related to a Speaking Up report.A person can raise a concern using our whistleblowing channels, including our reporting system ‘Concern Online’ and our Whistleblower Hotline. Both channels enable anonymous reporting.Westpac’s Whistleblower Protection Officers are responsible for protecting whistleblowers against personal disadvantage as a result of speaking up. They also engage with whistleblowers to address risks of reprisal. Whistleblowers may also raise a concern directly with a Whistleblower Protection Officer.The Speaking Up Policy requires that we investigate concerns in a confidential, fair and objective manner. If the investigation shows that wrongdoing occurred, we are committed to taking action, such as changing our processes and imposing consequences on those involved in wrongdoing. Outcomes may also involve reporting the matter to relevant authorities and regulators.The Board Audit Committee, in conjunction with the Board Risk Committee oversees Westpac’s Whistleblower Program. The Board Risk Committee receives regular reporting on whistleblowing (which includes key metrics, measures and themes that provide insights into the performance of the Whistleblower Program).Material whistleblower matters reported under the Westpac Group Speaking Up Policy are reported to the Board Risk Committee.1Westpac’s Speaking Up Policy is available on our website at: www.westpac.com.au/about-westpac/westpac-group/corporate-governance/principles-policies/.1.

Anti-Bribery and CorruptionThe Westpac Group has an Anti-Bribery and Corruption (ABC) Policy, an ABC Standard, and bribery prevention procedures and systems. Material breaches of the ABC Policy are reported to the Board Risk Committee.1 The ABC Policy is available on our website at www.westpac.com.au/about-westpac/westpac-group/corporate-governance/anti-bribery-corruption-policy-procedures/.Westpac has no tolerance for any form of bribery or corruption. This includes a ban on facilitation payments and offering or soliciting secret commissions.Westpac is committed to preventing, detecting and deterring bribery and corruption by managing its bribery and corruption risk and complying with relevant ABC legislation in all jurisdictions in which it operates or has dealings. This includes the Australian Criminal Code Act 1995 (Cth), the Bribery Act 2010 (UK) and the Foreign Corrupt Practices Act 1977 (US).Under the ABC Policy, Westpac expects that its officers, Directors, employees, agents, contractors, service providers and subsidiaries and third parties acting for or on behalf of Westpac will comply with all applicable ABC laws and will not offer, provide, authorise, request or receive a bribe or anything which may be viewed as a bribe.Westpac is required to design a system of internal controls, maintain accurate books and records and keep accurate records under the Foreign Corrupt Practices Act 1977 (US).Westpac must also put in place adequate procedures as a defence to bribery under legislation including the Bribery Act 2010 (UK). Adequate procedures must be proportionate to the bribery and corruption risks that Westpac may reasonably face.Fit and Proper Person assessmentsWestpac’s Board approved Group Fit and Proper Policy (F&P Policy) outlines how we assess the fitness and propriety of our Directors, Accountable Persons under BEAR, and other individuals in key positions of responsibility.The F&P Policy supports Westpac in complying with APRA Prudential Standards CPS 520 and SPS 520, the Banking Act 1959 (Cth) (including BEAR), Superannuation Industry (Supervision) Act 1993 (Cth), relevant ASIC licensing requirements (Australian Financial Services Licence and Australian Credit Licence) and equivalent offshore regulations as applicable.

In all cases, a fit and proper assessment will be undertaken prior to their initial appointment and be re-assessed annually. This involves the relevant individual providing a declaration and background checks (including police and bankruptcy checks) being undertaken as appropriate.Conflicts of interestWestpac’s conflicts of interest framework is designed to identify and manage conflicts of interest. The conflicts of interest framework includes the Group Conflicts of Interest Policy, along with supporting policies, standards and procedures.Under our conflicts of interest framework, any person who acts on behalf of the Westpac Group must: —promptly identify, declare, assess, manage and record conflicts of interest appropriately; —discharge their duties concerning conflicts of interest with integrity, fairness, honesty and due skill, care and diligence; —avoid a conflict of interest where it cannot be effectively managed; and —not solicit, accept or offer money, gifts, favours or entertainment that might influence, or might be seen to influence, their professional judgement.Modern SlaveryUnder the Modern Slavery Act 2018 (Cth) and Modern Slavery Act 2015 (UK), Westpac is required to prepare an annual statement describing the risks of modern slavery practices in our operations and supply chain, and the actions taken to address these risks. Westpac published a joint statement for FY21 on behalf of itself and certain reporting entities that addressed the requirements of both Acts.

SustainabilityWe view sustainable and responsible business practices as important for our business, our customers, our community and shareholder value. Sustainability is about managing environmental and social risks and opportunities in a way that seeks to balance the long-term needs of all our stakeholders – our customers, employees, suppliers, investors and community partners – together with the needs of the wider community and the environment.We aim to address the matters that we believe are the most material for our business and stakeholders, now and in the future. We understand that environmental and social risks and opportunities continue to evolve so we seek to monitor and progressively embed the management of sustainability into business practice. While striving to deliver against our sustainability strategy, we also work to anticipate and shape our response to emerging social and environmental issues where we believe we have the skills and experience to make a meaningful difference and drive business value.ReportingWe report on the most material sustainability matters (including environmental and social risks and opportunities), identified in our annual materiality assessment, to internal and external stakeholders Details of how we seek to manage the associated risks and opportunities and our performance against our sustainability strategy are contained in our half and full year reporting suite, available on our website. We participate in a number of voluntary initiatives including the Global Reporting Initiative (GRI), Taskforce on Climate-Related Financial Disclosures (TCFD), the Equator principles and the UN Global Compact. Our sustainability reporting is subject to independent limited and reasonable assurance, performed in accordance with the Australian Standard on Assurance Engagements 3000 Assurance Engagements Other Than Audits or Reviews of Historical Financial Information (Revised) (‘ASAE 3000’). The assurance provider also assesses whether our sustainability reporting is based on the GRI Universal Standards 2021 and the Sustainability Accounting Standards Board (SASB), and aligned with the reporting and self-assessment requirements of the Principles for Responsible Banking (PRB).Material exposure to sustainability risksWestpac is exposed to environmental and social risks such as climate change risk. We seek to manage our material exposures to these risks in accordance with our risk management strategy and frameworks.Further details about the risks we face, and how we seek to manage them, are referred to in our 2022 Annual Report (see pages 34 to 51 and pages 134 to 152). In addition our Climate Change Position Statement and Action Plan, our Human Rights Position Statement and Action Plan, and our Modern Slavery Statement are available on our website at www.westpac.com.au/about-westpac/sustainability/.Risk ManagementOur Risk Management Framework describes our approach for managing the material risks we face, and has nine components underpinned by a strong risk culture and a Three Lines of Defence model with customers at the centre. This is represented in the diagram on page 18.Effective risk management requires all the elements of our framework to operate independently and interactively to provide a complete approach for managing risk and to deliver fair customer outcomes.Westpac remains focused on implementing our integrated CORE program, which is designed to deliver a sustained uplift in outcomes for customers and how we manage risk. Key elements of the CORE program involve embedding our Risk Management Framework and strengthening our risk culture.The Group Risk Management Framework, Group Risk Management Strategy and Board Risk Appetite Statement are reviewed annually by the Board Risk Committee. The Board Risk Committee also oversees that Westpac is operating with due regard to risk appetite. The review of the Risk Management Framework includes consideration of whether the framework continues to be sound. The Group Risk Management Framework, Group Risk Management Strategy and Board Risk Appetite Statement were approved by the Board, on the recommendation of the Board Risk Committee, during the financial year ended 30 September 2022.The CEO and Executive Team are responsible for implementing our Risk Management Framework and Risk Management Strategy, and for developing frameworks, policies, controls, processes and procedures for identifying and managing risk in Westpac’s activities.To support our management of risk, Westpac has an Executive Risk Committee (RISKCO) that assists accountable individuals in making risk related decisions in respect of the Group. It monitors material risk exposures, their alignment to risk appetite approved by the Board and related actions. RISKCO also oversees the implementation and performance of the Risk Management Framework and execution of the Risk Management Strategy, as well as required controls and actions. RISKCO is supported by a number of management risk committees. RISKCO and these committees provide an important channel for senior management to communicate and report on risk matters.17 WESTPAC GROUP 2022 CORPORATE GOVERNANCE STATEMENT INTRODUCTIONTHE BOARDOPERATION OF THE BOARDDIVERSITY, ETHICAL DECISION MAKING, KEY POLICIES & SUSTAINABILITYRISKFINANCIAL REPORTING AND DISCLOSURE

Risk CultureWestpac considers that a strong risk culture is essential for the Group’s Risk Management Framework to operate effectively. Building and maintaining a strong risk culture is a continuing focus of the Board and will help us create a simpler, stronger bank.Westpac is working to enhance and improve its risk culture, which APRA had identified as being immature and reactive.As part of this ongoing work, Westpac has developed and implemented processes and tools to continue to improve risk culture, and track progress towards our goal of a risk culture that proactively identifies, manages and mitigates risks, learns from risk events and continuously anticipates new risks and opportunities. We have also implemented a Group-wide learning program which provides an opportunity for employees to spend time on the specifics of risk management.Further information about this work is available in the Strategic Review in our 2022 Annual Report.Three Lines of DefenceWe have adopted and continue to embed a Three Lines of Defence model which is designed to enable all our people to understand their own role and responsibilities in the active management of risk.Westpac is continuing to upgrade its end-to-end risk management capabilities as part of an ongoing program of work that spans both financial and non-financial risk. A key component of this work is embedding our Three Lines of Defence approach to improve accountability, the control environment and risk management awareness.

Financial reporting and auditApproach to financial reportingOur approach to financial reporting reflects three core principles: —that our financial reports present a true and fair view of our financial position and performance; —that our accounting methods comply with applicable accounting standards and policies; and —that our external auditor is independent and serves security holders’ interests.The Board, through the Board Audit Committee, has regard to Australian and international developments relevant to these principles when reviewing our practices.The Board delegates oversight responsibility for the integrity of financial statements and financial reporting systems to the Board Audit Committee. The Board Risk Committee provides relevant periodic assurances and reports (as appropriate) to the Board Audit Committee. Similarly, the Board delegates oversight responsibility for the preparation of remuneration reports and disclosures to the Board Remuneration Committee, which recommends remuneration reports and related disclosures, and provides relevant assurances, through the Board Audit Committee to the Board for approval.CEO and CFO assuranceThe Board receives regular reports from management about our financial condition and operational results, as well as that of our controlled entities. Before the Board approves the half year and full year financial statements, the CEO and the CFO declare to the Board that in all material respects: —Westpac’s financial records:• correctly record and explain its transactions, and financial position and performance;• enable true and fair financial statements to be prepared and audited; and• are retained for seven years after the transactions covered by the records are completed; —the financial statements and notes comply with applicable accounting standards; —the financial statements and notes give a true and fair view of Westpac’s and its consolidated entities’ financial position and of their performance; —any other matters that are prescribed by the Corporations Act 2001 (Cth) and regulations as they relate to the financial statements and notes are satisfied; and —the declarations above have been formed on the basis of a sound system of risk management and internal control, and that the system is operating effectively in all material respects in relation to financial reporting risks.The CEO and CFO have provided such statements for the financial year ended 30 September 2022.External auditorOur external auditor is PricewaterhouseCoopers (PwC), appointed by shareholders at the 2002 AGM. Prior to 2002, individuals who were partners of PwC or its antecedent Firms were our external auditors from 1968. Our PwC lead audit partner is Mr Colin Heath. Mr Colin Heath assumed responsibility for this role in December 2021.The external auditor receives all Board Audit Committee and Board Risk Committee papers, attends all meetings of these committees and is available to Committee members at any time. The external auditor also attends the AGM to answer questions from shareholders regarding the conduct of its audit, the audit report and financial statements and its independence.PwC is required to confirm its independence and compliance with specified independence standards at our half and full financial year, however in practice it confirms its independence on a quarterly basis.We strictly govern our relationship with the external auditor, including restrictions on employment, business relationships, financial interests and use of our financial products by the external auditor.Periodically, the Board Audit Committee consults with the external auditor without the presence of management about internal controls over financial information, reporting and disclosure and the fullness and accuracy of the Group’s financial statements. The Board Audit Committee also meets with the General Manager, Group Audit without other members of management being present.Engagement of the external auditorTo avoid possible independence or conflict issues, our ‘Pre-approval of engagement of PwC for audit and non-audit services’ policy (NAS Policy) prohibits the external auditor from carrying out certain types of non-audit services for Westpac. The NAS policy also limits the extent to which PwC can perform other non-audit services. Use of PwC for any non-audit services must be assessed and approved in accordance with the pre-approval process set out in the NAS Policy. WESTPAC GROUP 2022 CORPORATE GOVERNANCE STATEMENT 20

Group Audit (internal audit)Group Audit is Westpac’s internal 3rd line assurance function that provides the Board and Board Committees and the CEO with independent and objective evaluation of the adequacy and effectiveness of the Group’s governance, risk management and internal controls.Group Audit is governed by a charter approved by the Board Audit Committee that sets out its purpose, role, scope and responsibilities. The General Manager, Group Audit has a direct reporting line to the Chairman of the Board Audit Committee and an administrative line to the CFO.Group Audit also has the right to unrestricted and private access to the CEO, the Board Chairman and Chairman of the Board Audit Committee, and other Board members where relevant and external regulators. Group Audit’s responsibilities include regularly reporting to the relevant Board Committees.Board Audit Committee dialogue with management, external audit and Group auditThe Board Audit Committee maintains an ongoing dialogue with management, the external auditor and Group Audit, including regarding those matters that are likely to be designated as Key Audit Matters in the external auditor’s report. Key Audit Matters are those matters which, in the opinion of the external auditor, are of the most significance in their audit of the financial report. As part of its oversight responsibilities, the Board Audit Committee also conducts discussions with a wide range of internal and external stakeholders including: —the external auditor, about our major financial reporting risk exposures and the steps management has taken to monitor and control such exposures; —Group Audit and the external auditor concerning their reports regarding significant findings in the conduct of their audits, and oversee that any issues identified are rectified by management in an appropriate and timely way or reported to the Board Risk Committee (with the Board Risk Committee overseeing management’s response to rectifying those issues); —management and the external auditor concerning the half year and full year financial statements; —management and the external auditor regarding any correspondence with regulators or government agencies, and any published reports which raise material issues or could impact on matters regarding the Westpac Group’s financial statements or accounting policies; and —the Group General Counsel regarding any legal matters that may have a material impact on, or require disclosure in, the financial statements. Market disclosure and shareholder communicationVerification of periodic corporate reportsFor periodic corporate reports released to the market which are not required to be audited or reviewed by our external auditor, we have verification and approval processes to support the integrity of the information disclosed. The process varies depending on the report and generally involves the individuals with responsibility for the information confirming to the best of their knowledge and belief that the information is considered to be accurate and not misleading. The process may also involve review by internal subject matter experts (and as appropriate, our external advisers); and review by and confirmation from the individual responsible for the corporate report that it is appropriate for release. Such periodic corporate reports may also, depending upon the report, be required to be approved by the Disclosure Committee or the Board under Westpac’s Market Disclosure Policy. Further details regarding Westpac’s Market Disclosure Policy are in the paragraph below.Market disclosureWe seek to provide all investors with equal, timely, accurate, balanced and meaningful information.Consistent with these standards, the Group maintains a Board-approved Market Disclosure Policy, which governs how we communicate with our shareholders and the investment community. The Market Disclosure Policy is available on our website at www.westpac.com.au/about-westpac/westpac-group/corporate- governance/principles-policies/. The policy provides a framework for how we manage our disclosure obligations and satisfy the disclosure requirements of the ASX, NZX, and other relevant offshore securities exchanges, as well as relevant securities and corporations legislation. Under our policy, and in accordance with our obligations, information that a reasonable person would expect to have a material effect on the price or value of our securities must first be disclosed via the ASX unless an exception applies under regulatory requirements.Our Disclosure Committee is responsible for (among other things) determining whether matters within management’s authority should be disclosed publicly under the policy, and for assisting employees in understanding what information may require disclosure to the market on the basis that it is market sensitive.Certain disclosure decisions (for example, relating to matters of fundamental importance to the Group including announcements concerning financial results or material equity raisings, transactions or changes in strategic direction) are the responsibility of the Board.21 WESTPAC GROUP 2022 CORPORATE GOVERNANCE STATEMENT INTRODUCTIONTHE BOARDOPERATION OF THE BOARDDIVERSITY, ETHICAL DECISION MAKING, KEY POLICIES & SUSTAINABILITYRISKFINANCIAL REPORTING AND DISCLOSURE
