National Premier Leagues South Australia (abbreviated as NPL SA), a subdivision of National Premier Leagues (NPL), is a semi-professional football competition in the state of South Australia. National Premier Leagues is the second-tier football competition in Australia, which sits below the Hyundai A-League and Westfield W-League on the country’s football national pyramid. Football Federation Australia (FFA) embarked on a National Competition Review in October 2010, which aimed to review the football competition structure in Australia. The process of conducting the National Competition Review lasted for 20 months, and the review results were released in May 2012, in which FFA proposed to revitalise the country’s state-based competitions to promote the development of elite players. As a result of this review, National Premier Leagues was established in February 2013. At the time of establishment, NPL has five subdivisions, including football teams from five corresponding state-based federations, which are Football Federation South Australia, Football Federation Tasmania, Football Queensland, Football NSW, and Capital Football. The inaugural season of NPL SA began in March 2013. Currently, this competition is run and managed by Football South Australia (formerly known as Football Federation South Australia), which is a governing body of football issues in South Australia and a competition administrator for different levels of football games in the state.
