(3) Recent Developments

The sub-section entitled "Recent Developments" in the section entitled "Description of Australia and New Zealand Banking Group Limited and its Subsidiaries" on page 175 of the Base Prospectus shall be supplemented by inserting the below at the end of the above-mentioned sub-section:

"Australian anti-money laundering/counter-terrorism reforms

In November 2024, the Australian Parliament passed legislation to reform the Anti-Money Laundering and Counter-Terrorism Financing Act 2006 (Cth) (the "Australian AML/CTF Act"), resulting in changes to regulatory requirements including those relating to AML/CTF programs, risk assessments, customer due diligence, reporting of suspicious matters reports, transaction threshold reports and transfers of value ("Australian AML/CTF Reforms"). The Australian AML/CTF Reforms were supported by new and amended AML/CTF Rules issued in August 2025, which set out how certain obligations are to be implemented. In March 2026, further amendments to the Australian AML/CTF Act were introduced in the Australian Parliament. If passed, those amendments will introduce further changes to AML/CTF obligations.

The Australian Government has issued transitional rules that defer the commencement of certain key obligations under the amended Australian AML/CTF Act. Most notably, the 'Initial Customer Due Diligence' requirements have now been deferred until 31 March 2029. Except for the matters covered in the transitional rules, most of the reforms came into effect on 31

---

March 2026 for current reporting entities, including those in the ANZBGL Group.

Full compliance with these reforms will involve complex technology upgrades to onboarding, operating systems and reporting systems. In addition, associated policies, procedures and staff training will also require substantial updates. This means that implementation will be a multi-year undertaking and the ANZBGL Group was not compliant with all new requirements as at 31 March 2026. AUSTRAC has acknowledged the tight timeframes and challenges for businesses in implementing the reforms. In line with AUSTRAC's published guidance, the ANZBGL Group will maintain its current money laundering controls, which are intended to ensure ongoing compliance with those controls during the transition. The ANZBGL Group has developed an implementation plan that specifically address money laundering /terrorism financing and proliferation financing risks.

The ANZBGL Group will monitor progress against the implementation plan, adapting it as required during this implementation phase. Key risks associated with the Australian AML/CTF Reforms include misalignment of the ANZBGL Group's implementation plan with AUSTRAC expectations or transitional rules (including timeframes), delays, or failure to achieve intended compliance outcomes, exposing the ANZBGL Group to regulatory scrutiny, enforcement, and penalties. Failure to adequately update systems and processes to address increasingly complex financial crime risks (including during the transition) may also result in breaches of AML/CTF and other laws, leading to significant financial penalties, reputational damage, or a material adverse impact on the ANZBGL Group's Position.

ANZ Group's 2026 Half Year Result and Proposed Interim Dividend

Overview of financial performance

The ANZ Group announced on 1 May 2026 a Statutory Profit of $3.65 billion for the half year ended 31 March 2026 ("1H26") and a Common Equity Tier 1 ("CET1") ratio at 31 March 2026 of 12.39%, up 36 basis points ("bps") from 30 September 2025.

Balance sheet metrics	30 Sep 2025	31 Mar 2026	31 Mar 2026 vs 30 Sep 2025
APRA Level 2 CET1 ratio, %	12.03	12.39	+36bps
Customer deposits, $b	748	771	+3% (+2%*)
Net loans and advances, $b	829	822	-1% (+1%*)

*Excluding Markets division

Credit quality

• Portfolio losses remain low, reflecting continued strong overall credit quality and limited impact from the Middle East conflict during 1H26.
• The 1H26 Individual provision ("IP") charge was $148 million, $20 million lower than for the half year ended 30 September 2025 ("2H25"). This represents a 4bps annualised IP loss rate, in line with the levels for the full year ended 30 September 2025 ("FY25").
• Conflict in the Middle East is translating to greater economic uncertainty, with expectations of lower growth, higher inflation and interest rates likely to challenge some customers.
• The 1H26 Collective provision charge was $126 million, which included a $175 million charge for the potential impacts of the Middle East conflict partially offset by improvement in underlying portfolio credit quality.
• The Collective provision balance increased to $4.45 billion, with a Collective provision balance to credit risk weighted assets coverage ratio of 1.22%, up 4bps from 30 September 2025.
• Non-performing exposures to total credit exposure was 0.55% at 31 March 2026, down 2bps from 30 September 2025.

---

Capital, funding, liquidity and dividend

• Level 2 CET1 capital ratio was 12.39% at 31 March 2026. The increase from 12.03% as of 30 September 2025 includes the return of surplus capital to ANZBGL, including capital from ceasing the remaining ~$800 million of the share buy-back as announced in October 2025, as well as the discounted dividend reinvestment plan utilised for the final 2025 dividend.
• The ANZGHL Board has proposed a 2026 interim dividend of 83 cents per share, with franking rising from 70% to 75% driven by an improvement in the Australian geography performance.
• Current capital levels are appropriate. As a result, no discount will apply to the dividend reinvestment plan ("DRP") for the interim dividend, which will now be neutralised through an on-market purchase of shares.
• Liquidity ratios remained broadly stable in 1H26, with the average liquidity coverage ratio of 132% and a net stable funding ratio of 115% at 31 March 2026, both remaining well above regulatory minimums.
• $15.5 billion of term wholesale debt was issued across the ANZBGL Group in 1H26."
