The Australian Council of Salaried and Professional Associations was formed on 17 October 1956 by an amalgamation of the Salaried Employees' Consultative Council of New South Wales and the Council of White Collar Associations, Melbourne. With divisions in Queensland, New South Wales, Victoria, South Australia and Western Australia, the Association merged into the Australian Council of Trade Unions in 1979.

The Federation of Scientific and Technical Workers was formed on 16 September 1943 by a joint committee of the Australian Association of Scientific Workers and the Federated Scientific Employees' Association. The latter body sank its identity into the new Federation but the Australian Association of Scientific Workers continued as a separate organisation. For some time, the Victorian body acted virtually as the Federal body but as other branches became established, the registered office of the Federation moved to Sydney in August 1946. The Federation was registered federally as a union in September 1946 and was deregistered in 1971.
