Greater Bank, a major Australian customer-owned mutual bank headquartered in New South Wales, operated for many decades under the corporate name Greater Building Society. Founded originally in the mid-twentieth century as a terminating building society that evolved into a permanent cooperative housing society, the institution expanded its branch network significantly across regional New South Wales and Queensland. After receiving formal regulatory approval from the Australian Prudential Regulation Authority to transition its institutional classification, the society officially changed its name to Greater Bank to accurately reflect its comprehensive range of retail banking products and modern financial services.
