Player transactions
Free agency negotiations have been delayed until 15 July 2020, after the NBL and the Australian Basketball Players' Association postponed the original start date of 30 March 2020 due to the COVID-19 pandemic. On 17 April 2020, the NBL, the Australian Basketball Players' Association and the nine clubs reached an agreement in response to the financial pressure caused by the coronavirus pandemic, which reduced the salaries of players signed for the 2020–21 season, lowered the full-time roster positions from 11 to 10 players and from three import slots to two import slots.Coaching transactions
