Division Three will operate with an eight-pool set-up in 2023/24 before moving to a new format for the following season.
From 2024/25, the eight pools will be merged into four pools of ten teams to allow a smoother promotion and relegation process with the two pools of Division Two with one promotion place available from each Division Three pool to Division Two.
It means Division Three will be capped at 40 teams. The teams from the current 82-strong cohort which fall below the cut-off point will play in the NBL Conference pools, where they will be joined by any new teams that apply to join the league.
There will be annual promotion and relegation between the Conference pools and D3 pools, with promotional playoffs determining these places. The top Conference teams will playoff against the bottom places of D3.
“The new Conference pools will create a more suitable introduction to NBL basketball than the current D3 tier and allow a fairer and more seamless promotion and relegation processes between D3 and D2.”
