The Woolclassers' Association of Australia was formed originally from the Woolclassers' Association of New South Wales which covered woolclassers in country sheds, as shearers and most other shed hands were covered by the Australian Workers' Union, and classers working in woolstores by the Federated Storemen & Packers' Union. The Association applied for federal registration, which it obtained in 1933, and changed its name to the Woolclassers' Association of Australia. A Victorian Branch (from 1945 the Victorian/Tasmanian Branch) affiliated late in 1934 and a South Australian Branch affiliated in 1949. The Woolclassers' and Experts' Association of Western Australia which had existed since 1919 affiliated in 1950. A Queensland Branch was formed in 1962, and the Riverina sub-branch in 1963.
