Bank Australia is an Australian customer-owned bank based in Collingwood, Victoria. The organisation can trace its origins back to 1957, when the CSIRO Co-operative Credit Society was formed. Over succeeding years, mergers among 72 other credit unions and co-operative banks eventually led to the creation of the Members & Education Credit Union (mecu) in 2003, which became Bankmecu in 2001, and Bank Australia in 2015. Bank Australia is a member organisation of the Australian Banking Association, the Global Alliance for Banking on Values, and is a certified B Corporation.
