The Municipal Officers' Association of Australia was formed in 1920 and was registered in 1921. It grew from a small and politically conservative union into a large and more vocal organisation. In 1991 it amalgamated with the Australian Transport Officers' Federation and the Technical Service Guild of Australia to form the Australian Municipal Transport Energy Water Ports Community and Information Services Union. After amalgamations with other unions in 1993, it changed its name to the Australian Municipal Administrative Clerical and Services Union, known as the Australian Services Union.

The union known as the Australian Services Union began in 1991 as an amalgamation of the Technical Service Guild of Australia, the Municipal Officers' Association of Australia and the Australian Transport Officers' Federation and took the name the Australian Municipal Transport Energy Water Ports Community and Information Services Union. It retained this name after amalgamation with the Australian Social Welfare Union and the Western Australian Railway Officers' Association in 1992 and with the Australian Shipping and Travel Officers' Association in 1993, but changed its name to the Australian Municipal Administrative Clerical and Services Union later in 1993 after amalgamation with the Federated Clerks' Union of Australia and the Federated Municipal and Shire Council Employees' Union of Australia. In 1994, the Totalisator Employees' Association of Victoria was incorporated in the union.
