Media Release

St.George and Westpac sign Merger Implementation Agreement
to form Australia’s leading financial services company

26 May 2008

·Creating Australia’s leading financial services company for customers, shareholders and employees

·St.George shareholders to receive 1.31 Westpac shares for each St.George share

·Retaining St.George, BankSA and Asgard brands with no net reduction in ATM or retail network

·AA rated financial institution, with strong capital and broad based funding

St.George Bank Limited and Westpac Banking Corporation today announced that, following the successful completion of due diligence by both organisations, they have signed a Merger Implementation Agreement (MIA). This reflects the key commercial terms which have been agreed by the boards and under which the recommended proposal will be put to a vote of St.George shareholders.

Westpac Chairman Ted Evans said: “The merger of Westpac and St.George will ultimately deliver improved customer service with strong brand support, enhanced returns for shareholders and a strong commitment to community initiatives. The combination of both organisations’ strengths and leading customer advocacy will create a compelling proposition for all stakeholders.”

St.George Chairman John Curtis said: “The proposed merger will allow the distinctive brands, culture and customer service focus of St.George to be retained and strengthened. This should greatly enhance customer experience and shareholder value.”

“The St.George board intends to recommend to its shareholders Westpac’s offer of 1.31 Westpac shares for each St.George share. The recommendation is subject to an Independent Expert’s report concluding that it is in the best interests of our shareholders, no superior proposal emerging, and the St.George board continuing to hold the view that the proposed merger is in the best interests of St.George shareholders, compared to the position when the proposed merger was announced on 13 May 2008.”

St.George shareholders will receive a final dividend for the 2008 financial year, which is anticipated to be in accordance with St.George’s usual dividend payout ratio.

The merger is expected to be cash earnings per share accretive for St.George shareholders from the first full year of the merger. The merger is expected to be cash earnings per share accretive for Westpac shareholders within three years of the merger.

Merger Rationale

The proposed combination of Westpac and St.George is a compelling proposition for stakeholders:

·All Westpac and St.George brands, including BankSA, Asgard and branch/ATM networks will be retained. The intention is that there will be no net reduction in branch or ATM numbers. A corporate presence will also be retained in Kogarah. The focus will be on investing more in front-line services.

·The combined 10 million customers would benefit from an enhanced offering in terms of product range, expanded distribution and financial strength, and preserving their relationships with existing employees, products, customer touch points and branding.

The merger will create Australia’s leading financial institution. Together, Westpac and St.George will have a AA credit-rating, putting the merged entity in a strong position in the current environment.

Westpac CEO, Gail Kelly said this merger creates a springboard for growth with strong brands, leading products and an extensive distribution network.

“The customer-focussed cultures of both St.George and Westpac are fundamental to this merger. Customer service will be enhanced as the increased scale and integration of operations will drive further investment in our back office processes. Each bank’s customers will also benefit from greater diversity and choice of products from both organisations,” Mrs Kelly said.

Mr Paul Fegan, CEO of St.George Bank said: “The combined entity will provide greater choice of product, convenience and customer service. This is a very appealing proposition for customers and will create a world class financial services organisation for all our stakeholders.”

Merger Implementation Agreement Key Points and Anticipated Timing

The signing today of the MIA has followed two weeks of reciprocal due diligence.

The MIA outlines the anticipated timetable and binding terms and conditions on which both parties can now proceed to implement the merger proposal via a scheme of arrangement. A copy of the MIA is annexed to this announcement.

The MIA is subject to a limited number of standard conditions precedent, including no material adverse change, no prescribed occurrences and obtaining all necessary regulatory approvals. Full capital gains tax rollover relief is expected to be available for St.George shareholders for the Westpac shares they would receive under the merger.

The exclusivity period, which provides for St.George to work exclusively with Westpac, has been extended under the MIA. This does not prevent St.George from considering

any superior proposals which may emerge. There are no break fees provided for in the MIA.

St.George shareholders will receive a scheme booklet, which will contain full details of the proposal, including the basis for the St.George Directors’ recommendation and an Independent Expert’s report. It is currently anticipated that this booklet will be dispatched to shareholders by early October 2008, subject to relevant regulatory approvals, and that St.George shareholders will vote on the proposed merger by early November 2008, with finalisation of the merger envisaged for late November 2008.

Conclusion

Mr Evans added that he was confident that St.George shareholders would find the all- scrip merger proposal compelling and that he looked forward to welcoming St.George’s shareholders as owners of Australia’s leading financial services company.

“This partnership capitalises on a unique opportunity to bring these two organisations together in a way that provides benefits to all stakeholders, by building upon the strong foundations of both sets of brands to deliver a truly leading financial services company for customers, shareholders and employees,” Mr Evans said.

“The St.George board believes this is an attractive proposal that will provide a range of benefits to our shareholders and additional opportunities for our customers,” Mr Curtis said.

(d)St.George must procure that, on or before 9.00am on the Business Day following the Scheme Record Date, details of the names, registered addresses and holdings of St.George Shares of every Scheme Participant as shown in the St.George Share Register at the

22 Proposed St.George / Westpac merger – 26 May 2008 Extensive case study review Analysed a number of deals around the globe for best practices, synergies attained and attrition levels. Close attention paid to multi-brand models with overlap. Similar models listed below. RBS and ANZ models considered most similar • Banco Commercial Portugues / Banco Portugues do Atlantico (1995) • Suncorp Metway / Promina (2007) • RBS / Natwest (1999) • ANZ / National Bank of NZ (2003) • Santander / Banesto (1994) • Credit Agricole / Credit Lyonnais (2003) • Merger creating largest New Zealand Bank • Customer, branch and product overlap: - NBNZ market leader in lending (23%) ahead of ANZ (15%) - ANZ stronger in institutional banking, NBNZ stronger in rural • Maintained customer facing divisions with multiple brands: - Separate management teams retained to manage separate brands - Drew on best resources regardless of bank - Customer satisfaction at time of deal was higher for NBNZ than ANZ - ANZ customer satisfaction improved through applying NBNZ model • Integrated back office, IT and NZ head office: - Combined group maintained market share - Lower cost synergies due to regulatory requirements • Biggest bank merger in British history • Customer, branch and product overlap: - 320 of 680 RBS branches in England - RBS favoured by Scottish customers; NatWest favoured by English • Maintained customer facing divisions with multiple brands: - No branch closures - Most NatWest customers unaware of change in ownership • Integrated back office and corporate: - 29% cost synergies - 26% revenue synergies - Less than 5% customer attrition - Fully integrated in 3 years ANZ / NBNZ merger (2003) Royal Bank of Scotland / NatWest merger (2000) Source: Bain & Company research 2008

23 Proposed St.George / Westpac merger – 26 May 2008 Managing the risks Mitigants Risk • Commenced dialogue with regulatory and government authorities • Confident of satisfying regulatory authorities given nature of transaction Government/ Regulatory • Establishing an independent team comprising both St.George and Westpac employees • Teams focused on momentum, cost synergies and revenue opportunities • Deep knowledge and understanding of St.George and its culture • Extensive integration experience Integration • Proposed business model maintains brands and distribution, protecting customer relationships • Early additional benefits to customers e.g. expanded ATM distribution • Further building brands and brand capability Attrition • Confident of maintaining AA rating for combined entity • All scrip transaction minimises cash funding • Combined 2009 term funding task comfortably achievable Funding

24 Proposed St.George / Westpac merger – 26 May 2008 Clear governance principles and processes • Appropriate arrangements for Westpac CEO in place: - Westpac CEO’s shares in St.George have been fully disclosed to Westpac Board - Westpac CEO does not vote on Westpac Board decisions on the transaction - Westpac CEO will not vote St.George shares on the scheme • Westpac CEO’s interests are aligned with Westpac shareholders: - Westpac CEO will only deal with Westpac scheme shares progressively over 3 years - Westpac CEO will maintain a significant Westpac shareholding

25 Proposed St.George / Westpac merger – 26 May 2008 Key accounting considerations - goodwill Equals Less Less • Goodwill deducted from Tier 1 and is subject to an annual impairment test Goodwill • Brand value calculated and deducted from Tier 1. Brand value is indefinite so will not change over time although the brand intangible subject to an annual impairment test. Any impairment charge will be a cash earnings adjustment. • Core deposit intangibles (‘CDI’) representing the value of deposit franchise, is estimated and its value is deducted from Tier 1. CDI value is subsequently amortised over average estimated life. Amortisation impacts statutory NPAT but is reversed for cash earnings • Other small intangible items likely to be treated similar to CDIs. Identifiable intangibles • Fair value of assets and liabilities results in an adjustment to intangibles/goodwill (may be positive or negative) • Expect some change in the composition of balance sheet provisions and reserves to align accounting policies Fair value of net tangible assets acquired • Share price times shares issued is added to Tier 1 Consideration Comments Accounting items In aggregate, Westpac’s Tier 1 ratio is expected to be similar post merger. Some small changes in Tier 1 may result from fair valuing net tangible assets

26 Proposed St.George / Westpac merger – 26 May 2008 No change to cash earnings principles Visa IPO BTIM IPO Integration and transaction costs1 Hybrid hedging NZD hedging Ineffective hedges Treasury shares Intangible amortisation1 Significant one off items that impact reported earnings These items are genuinely one-off in that they are unlikely to reoccur in future periods Items that have the potential for a material timing difference on reported earnings but would not impact returns available for shareholders An example would be where an effective hedge is in place but because hedge accounting is not available for certain transactions under A-IFRS, there may be differences in the value of the hedge verses the value of the underlying item at any point in time. We will adjust for these when they are material Items that permanently affect reported earnings but do not impact returns available to shareholders Such items typically have an accounting impact on earnings but no economic impact on earnings Cash Earnings Principles: The following adjustments are applied to NPAT e.g. e.g. e.g. 1. New cash earnings adjustments following proposed St.George merger

27 Proposed St.George / Westpac merger – 26 May 2008 Dividend FY2008 • The Merger Implementation Agreement (‘MIA’) seeks to ensure that neither St.George nor Westpac shareholders are disadvantaged in the transaction • St.George shareholders will receive a final dividend based on St.George earnings. Regardless of timing, St.George shareholders will not receive a Westpac final dividend for FY2008 • Westpac shareholders will continue to receive their interim and final year dividend in FY2008 with dividends based on Westpac earnings • Under the MIA, the separate Westpac and St.George final dividends payable are capped at 74 cents and 97 cents respectively. These caps reflect the merger exchange ratio of 1.31 Westpac shares for each St.George share. • Final dividends for both St.George and Westpac are expected to be paid in December 2008 • Both St.George and Westpac shareholders to begin receiving dividends from the combined entity from FY2009

The forward-looking statements include statements regarding our intent, belief or current expectations with respect to our business and operations, market conditions and results of operations and financial condition, including, without limitation, indicative drivers, forecasted economic indicators and performance metric outcomes. We use words such as ‘may’, ‘expect’, ‘indicative’, ‘intend’, ‘forecast’, ‘likely’, ‘estimate’, ‘anticipate’, ‘believe’, or similar words to identify forward-looking statements. These statements reflect our current views with respect to future events and are subject to certain risks, uncertainties and assumptions. Should one or more of the risks or uncertainties materialise, or should underlying assumptions prove incorrect, actual results may vary materially from the expectations described in this presentation. Factors that may impact on the forward-looking statements made include those described in the sections entitled ‘Risk factors,’ ‘Competition’ and ‘Risk management’ in Westpac’s 2007 Annual Report on Form 20-F filed with the U.S. Securities and Exchange Commission and in the section entitled ‘Principal risks and uncertainties’ in Westpac’s Interim Financial Report for the half year ended 31 March 2008 available at www.westpac.com.au. When relying on forward-looking statements to make decisions with respect to us, investors and others should carefully consider such factors and other uncertainties and events. We are under no obligation, and do not intend, to update any forward-looking statements contained in this presentation.
