The FFSA State League is the second tier state-level soccer competition in South Australia. The league is part of the Australian Premier League (APL) structure implemented by Football Federation Australia in 2012. It is conducted by the Football Federation South Australia (FFSA), the state's governing body. Each season, the top two clubs are promoted to the Premier League while the bottom two sides in the Premier League are relegated to the State League. In 2006 the league became third-highest level competition in South Australia. However, in 2012 the league reverted to being the second-highest level competition after the disbandment of the Super League. After the reforming of the South Australian football league structure in 2012, the league increased its participants from 10 clubs to 16.
In 2012 it was announced that the league would increase the number of clubs participating in the competition from 10 to 16 due to the disbandment of the South Australian top tier Super League. The new competition would include the 10 participating teams from the 2012 season and the addition 6 teams would be made up of the 6 bottom placed teams from the 2012 Premier League table.
