The National Premier Leagues Western Australia is a regional Australian semi-professional soccer league comprising teams from Western Australia. As a subdivision of the National Premier Leagues, the league is sits at the highest level of the Western Australian league system (Level 2 of the overall Australian league system). The competition is administered by Football West, the governing body of the sport in the state. In 2014, the league, formally known as the Football West State League Premier Division was rebranded into what exists today.
The West Australian National Training Centre included a team for the 2011-2013 seasons. They did not play for competition points, and were mostly used for development of the upcoming youth players.
In 2013 Football Federation of Australia introduced the new second tier competition for football in Australia, the National Premier Leagues. In 2014 Football West then reorganised the former State Premier League league into the National Premier Leagues Western Australia conference and the Divisions one and two. There is a freeze in promotion and relegation between the NPL and the State League Division 1 for two seasons until the 2016 season, as there are plans for an expansion of teams in the NPL WA competition.
