2019–20 A-League

The 2019–20 A-League, also known as the 2019–20 Hyundai A-League for sponsorship reasons, was the 43rd season of national level soccer in Australia, and the 15th since the establishment of the A-League in 2004. The regular season commenced on 11 October 2019 and was scheduled to conclude on 26 April 2020, though was postponed to 19 August 2020 as a result of the COVID-19 pandemic. The pandemic caused Football Federation Australia (FFA) to suspend the season from late March to mid July. The season resumed on 17 July 2020, which meant the finals occurred in mid-August and the Grand Final was held on 30 August 2020.

Sydney FC were the defending champions and Perth Glory were the defending premiers.

Effects of the 2019–20 COVID-19 pandemic
Due to the self isolation requirements after overseas travel imposed by the Australian Government on 16 March, both Melbourne Victory and Wellington Phoenix were required to self-isolate having returned from playing in Wellington on 15 March 2020. This led to four games involving both clubs being postponed.

On 16 March 2020, due to restrictions imposed by the Australian Government of gatherings involving more than 500 people, the FFA announced that the remainder of the season would proceed with all games being played behind closed doors. Wellington Phoenix had intended to relocate for the remainder of the season in Sydney in order to keep playing the remainder of its scheduled games. The season was suspended on 24 March.

The season resumed on 17 July 2020, with almost all of the remaining 27 matches in the regular season played in New South Wales.
