The story

The Savings Bank of South Australia was established in the colony of South Australia on 11 March 1848 by sole employee John Hector. The first deposit comprised the life savings of an Afghan shepherd. The first premier of the colony, B. T. Finniss, was a trustee of the bank's inaugural board, and F. H. Robe, Lieutenant Governor of the colony, was president of the bank.

The Savings Bank of South Australia later merged with the former State Bank of South Australia (established 1896), becoming the new State Bank, owned by the Government of South Australia, in 1984.

The State Bank of South Australia was compartmentalised and bought by The Advance Bank due to deteriorating loan book and financial management. Prior to a bailout by the Government of South Australia, the Savings Bank was on the verge of collapse, which was hastened by the 1991 Royal Commission into The Organisation Of Public State Funds of South Australia. Advance Bank was purchased by St. George Bank in 1997 and the State Bank became part of the greater Westpac Corporation after the merger with St. George Bank.
