The AWU grew from a number of earlier unions, notably the Australasian Shearers' Union, founded by William Spence, Alexander Poynton (OBE, an inaugural member of the Australian House of Representatives), brother Charles Poynton, and David Temple in Creswick, Victoria in 1886. This union joined with shearers' unions in Bourke and Wagga in New South Wales to form the Amalgamated Shearers Union of Australasia in 1887. In 1894 this union amalgamated with the General Labourers Union, which had formed in 1891, to form the Australian Workers' Union.
