The season was suspended from August from government-imposed lockdowns, due to the impacts from the COVID-19 pandemic in Australia and cancelled in September. Tigers FC were the NPL1 Premiers (based on a points per match formula rather than aggregate points), and qualified for the 2021 National Premier Leagues final series; they were also the Federation Cup winner, and qualified for the 2021 FFA Cup.
