BankSA got its start in 1848 as two separate banks: the State Bank of South Australia and the Savings Bank of South Australia. The two banks would later merge as the Bank of South Australia, better known by its commercial name BankSA.
After mismanagement and bad banking in the 1980s, BankSA collapsed, was bailed out by the State Government, and merged with St.George Bank in 1992. It was decided to maintain the BankSA brand for operations in South Australia, with many of BankSA’s products and services being identical to St.George’s, including its credit cards. In 2008, both were absorbed by the Westpac Group.
