Professionals Australia, formerly the Association of Professional Engineers, Scientists and Managers Australia (APESMA), is an Australian employee association registered under state and federal industrial relations acts. Professionals Australia has approximately 25,000 members from the following professions: engineers, scientists, managers, architects, IT professionals, pharmacists, veterinarians, surveyors, translators and collieries staff in addition to student members. Professionals Australia is an example of a union that is organised along occupational lines. For this reason its coverage areas overlap substantially with industry unions which now represent the majority of union members in Australia. As it also covers managers, it is also in the unusual position that, in negotiations on behalf of employee members, the employer representatives with whom it is negotiating may also be union members. This makes it a trade union for the purposes of worker-employer bargaining; Professionals Australia is affiliated with the Australian Council of Trade Unions (ACTU). Professionals Australia acts to service member needs, primarily in terms of salary and industrial advice. This places Professionals Australia within the services model of trade unionism. It also performs many of the functions of a professional association. Professionals Australia is not affiliated to either major political party. Professionals Australia began as The Association of Professional Engineers, Australia (APEA) which formed in 1946 and registered as an industrial association in 1948. APEA was the first organisation to ensure that professionals be recognised and rewarded for the high-value work they do. The Professional Engineers Case finalised in 1961 saw engineers across Australia receive salary increases averaging more than 40 per cent. Even more importantly it set the precedent for work value and benchmark salaries for professionals. Professionals Australia has Government approval as an assessment entity for the only mandatory engineering registration scheme in Australia – the Registered Professional Engineers of Queensland (RPEQ). Professionals Australia offer assessment in the areas of Civil, Electrical, Information, Technology and Telecommunications, Management, Mechanical and Structural Engineering. APEA grew by a process of mergers of white collar, professional and management employee associations over a long period of years: 1991 : The Association of Professional Scientists, Australia 1991 : The Local Government Engineers Association of New South Wales 1994 : Senior Managers (Telstra & Australia Post) Association 1994 : ABC Senior Executives Association 1995 : Association of Architects of Australia 1997 : Salaried Pharmacists Association 1997 : Association of Railway Professional Officers of Australia 2001 : Australian Collieries Staff Association 2004 : Managers & Professionals Association 2006 : Professional Officers Association of Victoria (POAV) (formed as POA in 1917) APEA became APESA (Association of Professional Engineers and Scientists, Australia) in 1991, and APESMA (Association of Professional Engineers, Scientists and Managers Australia) in 1994. In 2013, in recognition of the many new professions represented by the union (including architects, pharmacists, translators and interpreters), APESMA changed its name to Professionals Australia. APESMA's journal for members is the Professional Network, published bi-monthly.
