Australia's universities are home to a variety of different student union groups, providing a range of political, commercial and other services to students. The sector has undergone substantial change in recent years, with a decline in participation, intervention by university administrations, and the end of compulsory membership arrangements. Although names such as union, student association, representative council and guild are common, in practice they provide little insight into an organisation's role on campus. In addition, some organisations have chosen to rebrand using entirely new names, with the term "union" in particular considered to be the source of misunderstandings about their role. Students at Macquarie and Arc @ UNSW are examples of this trend. Where campus unions are being replaced with university-owned corporate entities, non-traditional names such as UWS Connect and UniCentre are becoming common. History Early student unions The history of student union in Australian universities broadly reflects the changing nature of the student body in the Australian tertiary system. The earliest student body was a largely wealthy group. Entry into the University system was only available to the privileged and wealthy. The associations formed by this body reflected the social associations formed by this class of Australians: they were largely voluntary and focused on extending the social opportunities of their members. In the late 19th and early 20th century, at each University these organisations developed closer links with one another, and eventually transformed into unified student associations. The rise of radicalism By the 1930s, the Australian Labor Party was proving to be politically attractive to small groups of University students. These students formed Labour Clubs, dedicated to the ideas of the labour movement, and began to contest for leadership of student associations. The Labor Clubs were often opposed by independent conservative students, but often conservative students lacked the vast activist apparatus built up under the Labour Clubs. In the 1950s, the composition of the student body changed radically. The Menzies Government founded new technically oriented universities, like the University of New South Wales, and expanded the role of the technical tertiary colleges. This was in response to a perceived lack of graduate labour in the Australian economy. Increasingly, working class students were able to access University through teacher-training schemes, veterinary preference schemes, and other avenues. Bonded in labour to a government authority, these students could exert some level of pressure against their future "employer" by joining a union and
