Challenge Bank was an Australian bank. It was established in April 1987 when the Hotham Permanent Building Society of Victoria and Perth Building Society of Western Australia merged.[1][2] It produced one of the most iconic ads of the 1980s.[3] In December 1995 it was purchased by Westpac.[4] In May 1996, the Victorian business was sold to the Bank of Melbourne that in turn was purchased by Westpac in 1997.[5][6] The Challenge Bank brand was retired in the early 2000s.
