In 1924 the Railway and Tramway Officers' Association (registered in New South Wales in 1913) amalgamated with the first federally registered organisation of salaried officers, the Victorian Railways Administrative Officers' and Clerks' Association (formed in 1921) to become the Australasian Transport Officers' Federation. It changed its name in 1978 to the Australian Transport Officers' Federation. The Airlines Division held its inaugural meeting on 22 November 1980. By 1991 the union had merged with the Technical Service Guild of Australia and the Municipal Officers' Association of Australia to form the Australian Municipal Transport Energy Water Ports Community and Information Services Union. Further amalgamations in 1992 and 1993 with the Australian Social Welfare Union, the Australian Shipping and Travel Officers' Association, the Federated Clerks' Union and the Federated Municipal and Shire Council Employees' Union formed the Australian Municipal Administrative Clerical and Services Union, known as the Australian Services Union.
