In 2012 St George competed in the New South Wales Super League, the second tier of state soccer, finishing seventh out of twelve clubs and missing out on the finals. In 2013, St George were promoted from the NPL NSW Men's 2 after taking out the league championship, finishing seven points ahead of the second placed Macarthur Rams FC. The club also won the Grand Final, beating the Rams in the semi-final 2–1 and then beating Mounties Wanderers FC 3–1 in the final. The joy was not to last long, though, as in 2014, the club was immediately relegated back to the second tier of soccer in NSW. Managing just four wins and four draws in 22 games, St George finished dead last in the top tier. The Saints endured another tough season in 2015, finishing third last in the NPL NSW Men's 2.
