The National Premier Leagues Western Australia is a regional Australian semi-professional soccer league comprising teams from Western Australia. The league name is often abbreviated to NPL Western Australia or NPL WA. 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.
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 State League (Division One and Division Two). The NPL WA competition fields a Senior first team, as well as youth teams in the U20, U18, U16, U15, U14, U13 and U12 age groups. The Perth Glory FC Youth team competes in the Senior category - effectively as Perth Glory's reserve side - and has additional age restrictions.
There is a freeze in promotion and relegation between the NPL and the State League Division 1 until the end of the 2015 season, as there are plans for an expansion of teams in the NPL WA competition.
