Celebrating 200 years. • Westpac has a long and proud history as Australia's first and oldest bank. Established in 1817 as the Bank of New South Wales, we changed our name to Westpac Banking Corporation in 1982. • For 200 years, we have survived and thrived because we have been guided by the same purpose: to provide stability, to support customers and communities, and to help grow the economy. • Today, Westpac is Australia’s 2nd largest bank with a market capitalisation of A$108 billion and total assets of A$852 billion as at 30 September 2017. We are also one of the largest banking organisations in New Zealand. • Westpac is focused on its core markets of Australia and New Zealand, providing a comprehensive range of financial products and services including consumer, business and institutional banking and wealth management services. • With a strong position in our home markets, and 13.8 million customers, Westpac focuses on organic growth, growing customer numbers in our chosen segments and building stronger and deeper customer relationships. • A key element of Westpac’s approach is our portfolio of financial services brands, which enables us to appeal to a broader range of customers, and provides us with the strategic flexibility to offer solutions that better meet individual customer needs. • Westpac has also maintained the strength of its financial position, lifting the level and quality of our capital, improving our funding and liquidity position and maintaining a high level of asset quality and provisioning. • Westpac is currently one of the most efficient banks globally, as measured by the cost to income ratio.
