Mile Sterjovski scored first for United as they went up 1âÂÂ0 at the half time break, however, a goal from Paul Trimboli and a brace from John Anastasiadis sealed South Melbourne's second consecutive championship and fourth overall. Goran Lozanovski won the Joe Marston Medal.
Sydney United finished the season with the minor premiership through a 3âÂÂ1 win over the Adelaide Sharks on the final day of the season. South Melbourne finished one point from first place.
