Route to the final
The 2020–21 season was the league's sixteenth since its inception in 2005, and the 44th season of top-flight association football in Australia. Twelve teams competed in the regular season, with each team playing a total of 26 matches, resulting in an uneven fixture that involved some clubs meeting three times and others meeting only twice. The top six teams qualified for the finals series, which were played in a straight-knockout format, with the top two teams earning an automatic place in the semi-finals and the bottom four teams playing off in elimination finals. The two winners of the semi-finals met in the grand final. Melbourne City and Sydney FC qualified for the semi-finals by virtue of finishing first and second respectively, whilst Central Coast Mariners met Macarthur FC in the first elimination final and Brisbane Roar took on Adelaide United in the second elimination final. Macarthur defeated Central Coast Mariners two goals to nil, both goals coming in extra time and Adelaide United defeated Brisbane Roar two goals to one. As the top-ranked team, Melbourne City were paired with and defeated Macarthur, the lowest-ranked winning team, 2–0, for their semi-final, whilst Sydney FC were victorious against Adelaide United in the other semi-final, the scoreline being 2–1.Due to crowd restrictions imposed as a result of the COVID-19 pandemic in Victoria, Melbourne City's home semi-final was moved to Netstrata Jubilee Stadium in New South Wales.
