Ladder
The home-and-away regular season took place over 17 rounds between 3 February and 17 June, with nine teams in the Eastern Division and eight teams in the Western Division. Each team would play the other teams in their division twice and the teams in the opposing division once. This meant that Western Division teams played 23 games and Eastern Division teams played 24.

The NBL tie-breaker system as outlined in the NBL Rules and Regulations states that in the case of an identical win–loss record, the results in games played between the teams will determine order of seeding.
