Since the 1970 election, marking the beginning of democratic proportional representation (one vote, one value) and ending decades of pro-rural electoral malapportionment known as the Playmander, Labor have won 11 of the 15 elections. Spanning 16 years and 4 terms, Labor was last in government from the 2002 election until the 2018 election. Jay Weatherill led the Labor government since a 2011 leadership change from Mike Rann. During 2013 it became the longest-serving state Labor government in South Australian history, and in addition went on to win a fourth four-year term at the 2014 election.

Labor's most notable historic Premiers of South Australia include Thomas Price in the 1900s, Don Dunstan in the 1970s and John Bannon in the 1980s.
