2020 NBL1 season

The 2020 NBL1 season was due to be the second season of the NBL1 and the first to consist of multiple conferences and National participation.

After consisting of one conference in 2019, the 2020 NBL1 season saw South (Victoria and Tasmania) joined by North (Queensland) and Central (South Australia). Due to the COVID-19 pandemic, the season was cancelled before it started.

Background
After a successful first season in 2019, the National Basketball League (NBL) expanded the NBL1 in 2020 by introducing Basketball Victoria's inaugural 2019 league and teams as the new South Conference and partnering with Basketball Queensland and Basketball South Australia to make the Queensland Basketball League (QBL) and South Australian Premier League the new North and Central conferences.

The season was scheduled to begin on 14 March for the Central Conference, 18 April for the South Conference and 24 April for the North Conference. After conference finals in August, it was scheduled that clubs from all three conferences would converge on the State Basketball Centre in Melbourne in the first weekend of September for the NBL1 finals series.

Due to the COVID-19 pandemic, the league announced on 18 March that the start of the season was delayed until mid May. However, six days later, the entire season for all three conferences was cancelled.
