Overview
St.George Bank is an Australian banking brand headquartered in Sydney and owned by Westpac Banking Corporation. It developed from the St.George Co-operative Building Society, established in Hurstville on 6 May 1937, and initially focused on housing finance and savings products for customers in the Sydney region. The organization expanded through the post-war housing boom, building a substantial branch and agency network across New South Wales before becoming a bank and demutualizing in 1992. The modern St.George business reflects a series of mergers and acquisitions. Its corporate lineage includes the Cronulla & District Co-operative Building Society, which combined with St.George in 1945; the Victorian Savings and Loan Society, acquired in 1991; parts of Barclays Bank Australia, acquired in 1994; and Advance Bank, acquired in 1997. The Advance Bank transaction also brought the Bank of South Australia business into the group. That business continued to operate under the BankSA name, particularly in South Australia and parts of the Northern Territory, rather than being fully absorbed into the St.George identity. St.George became an early technology adopter among Australian building societies. In 1972 it connected an IBM mainframe to terminals across its network, allowing it to operate online banking infrastructure before many comparable institutions. The organization also survived a serious confidence event in 1979, when an on-air claim that a large building society was about to fail triggered a rush of withdrawals. St.George kept branches open and met withdrawal requests, preserving its ability to operate. After obtaining a banking licence and becoming a public company in 1992, St.George broadened beyond traditional building-society activities. Its services came to include retail deposits, residential mortgages, consumer finance, business banking, commercial property lending, invoice discounting, foreign exchange, trade finance, interest-rate hedging and automotive finance. Its automotive and business-finance operations have been associated with St.George Finance and St.George Motor Finance, with some Victorian activities later aligned with Bank of Melbourne. Westpac announced its intention to merge with St.George in May 2008. St.George shareholders approved the transaction in November, and the merger became effective on 1 December 2008. The all-share transaction valued St.George at approximately A$18.6 billion at announcement-era terms, and St.George shareholders received Westpac shares representing 28.1 percent of the enlarged Westpac entity. St.George and BankSA continued as customer-facing brands within the Westpac Group, although St.George ceased to be an independent listed banking company. In 2010 St.George was deregistered as a company and ceased to be a standalone authorised deposit-taking institution. The brand nevertheless remained active as part of Westpac's multi-brand strategy. Victoria was subsequently served through the relaunched Bank of Melbourne brand from 2011, replacing St.George branding there. St.George continues to concentrate on retail and business banking in Australia, with especially strong historical and current recognition in New South Wales and the Australian Capital Territory. It also maintains a national branch and ATM presence through the wider Westpac network and has used offshore back-office processing, including operations in Bangalore, India. Some processing activities have later been brought back to Australia.
History
St.George Bank traces its origins to the St.George Co-operative Building Society, formed in Hurstville, Sydney, in May 1937. The Cronulla & District Co-operative Building Society was established soon afterward, and the two organizations merged in 1945. They expanded rapidly during the post-war demand for housing finance, reaching 38 branches by 1955. The society became a permanent building society that year, allowing it to offer larger loans over shorter terms, and continued extending its branch network through Sydney and surrounding communities. The organization invested early in banking technology. In 1972 it installed an IBM mainframe linked to 30 terminals, making it one of the first building societies in Australia to operate online. Its development was not uninterrupted: in 1979 a radio broadcast warning that a major building society might fail prompted heavy withdrawals. St.George remained open and paid customers who sought to withdraw funds, while public reassurance from New South Wales Premier Neville Wran helped stabilize confidence. During the 1980s and 1990s, St.George moved from a mutual housing institution toward a diversified banking group. It acquired the Victorian Savings and Loan Society in 1991, obtained a banking licence and demutualized in 1992, and became a public company. In 1994 it acquired the retail, commercial banking and finance divisions of Barclays Bank Australia. In 1997 St.George acquired Advance Bank, which brought with it BankSA, the successor to the South Australian government-backed banking business. BankSA continued as a distinct brand and developed a particularly extensive branch network in South Australia. The enlarged group expanded beyond mortgages and deposits into commercial lending, specialist finance, automotive finance, foreign exchange, trade finance and interest-rate products. By the mid-2000s it was one of Australia's largest banking institutions outside the major national banks. For the 2005–06 financial year, the bank reported a record net profit of A$1 billion, according to the cited historical reference material. St.George's independence ended through its 2008 merger with Westpac. The transaction was announced in May, approved by shareholders in November and completed on 1 December 2008. St.George shareholders received Westpac shares, and the St.George and BankSA brands were retained within Westpac's multi-brand model. Greg Bartlett became chief executive of St.George after completion. In 2010 the company was deregistered and ceased to be a standalone authorised deposit-taking institution, although the brand continued operating within Westpac. The group's brand architecture changed further in Victoria when Westpac relaunched Bank of Melbourne in 2011. Bank of Melbourne replaced St.George as the principal Westpac-associated retail brand in that state. In 2016 St.George moved its headquarters to Tower 2 of the International Towers complex at Barangaroo in central Sydney. The brand has continued to serve Australian retail, small-business and commercial customers, with strong historical roots in New South Wales and an ongoing relationship with BankSA in South Australia. Some administrative and processing functions were moved to India during the 2000s, while later initiatives brought portions of card and operational processing back to Australia.
