<P> Former and current Australian professional soccer players are represented by the Professional Footballers Australia (PFA), a trade union affiliated with the Australian Council of Trade Unions and a member of FIFPro, the global representative organisation for professional footballers . The association tends to footballer's pay and conditions, and also protects footballers from unfair dismissal . </P> <P> According to FIFA's Big Count in 2006, a total of 970,728 people in Australia participated in the sport, with 435,728 registered players, and 535,000 unregistered players . These numbers were higher than the equivalents for other sport codes such as cricket, Australian rules football, rugby league and rugby union . In 2013, an audit on the sport by Gemba found that 1.96 million Australians were actively involved in the game as a player . When coaches, referees and fans are included it is estimated that involvement with the sport is around 3.1 million . </P> <P> In Australia, domestic soccer competitions run all year, with the competition season depending on the level of professionalism of the league . The professional league operates during the Australian summer season and semi-professional / amateur leagues compete during the Australian winter season . </P> <P> Since 1977, the league system in Australia has involved one national top tier league controlled by the national body and many leagues that run below within each state, with no promotion and relegation linking the two . As the third least densely populated country in the world, Australia's large geographical area and the spread of the population, concentrated mainly around urban areas, is reason for a lack in national competition and a greater focus on state - based competition . </P>
