Finals
The 2023 NBL Finals were played in February and March 2023, consisting of three play-in games, two best-of-three semifinal series and the best-of-five Grand Final series. In the semifinals, the higher seed hosts the first and third games. In the Grand Final, the higher seed hosts the first, third and fifth games. This will be the first season the league will introduce play-in games.

The top two seeds in the regular season will automatically qualify to the semifinals. Teams ranked three to six will compete in the play-in tournament. The third seed will play the fourth seed for third spot and the loser will play the winner of fifth or sixth for the fourth seed.
