The Hawthorn Basketball Association is a member association of the Victorian Basketball Association, which operates under the auspices of Basketball Australia. The HBA is approximately the twelfth largest with respect to numbers of registered players among the Victorian associations.

There are about 300 teams in the Saturday competitions, comprising some 2,400 registered players. Canterbury Cougars is the largest club in the HBA, with a reputation for being extremely well administered. The Association, like our Club, is run by volunteers, and all member clubs are expected to delegate representatives to the executive and committee - particularly the larger and more organised clubs.

The Junior Boys and Girls competitions run on Saturday afternoons - a decision taken to accommodate the school sport commitments of many of the players - and the availability of venues that are predominantly school facilities hired by the HBA on a regular and ongoing basis. Games are scheduled from 12.00pm until 6.00pm using a 45-minute schedule. Younger ages are generally scheduled earlier, but this is regularly varied to meet the combined scheduling needs for the many player-coaches and player-referees.

Two competitions run sequentially: Summer Competition covers School Terms 4 and 1, followed by Winter Competition covering Terms 2 and 3. These competitions are age-based on the 2-year groupings used throughout Australian basketball. The HBA uses Under 10, 12, 14, 16, 18 and 20 age groups to designate Winter Competitions and Under 11, 13, 15, 17, and 19 age groups for the Summer Competitions, although the player eligibility is assessed on the standard 31 December cut-off for both competitions. Up to 5 divisions of 6 to 8 teams each are run for the lower to middle age groups to cater for the numbers of teams and their varying experience and ability levels.

The HBA also runs various senior competitions during the week, and enters Hawthorn Magic representative teams in graded levels of Victorian Championships and Victorian Metropolitan Leagues on Friday nights. The HBA is a relatively young association, entering 16 teams across Boys and Girls Under 12, 14, 16 and 18 in 1999. Representative teams provide both additional training and development for keen players. 

Representative team rankings provide a good guide to the relative standard of basketball played in the Saturday Competition. At the junior levels for 1999, Hawthorn Magic reached the highest grade (Championship) for the Under 12 and 14 Boys teams and the second highest grades for the Under 12 and 16 Girls teams. The best players from the Saturday competitions play in these elite level and high level competitions on Friday nights. Players from HBA have also previously won selection in Victorian teams.
