Two competitions run sequentially: Summer Competition covers school terms 4 and 1, followed by the Winter Competition in terms 2 and 3. There are no games on public holiday weekends or during school holidays. The competitions are age-based on the 2-year groupings used throughout Australian basketball.
Player eligibility is assessed on the standard 31 December cut-off in the year that the season ends for both competitions. Each age group will have a number of divisions, depending upon team numbers.
