The ACC conducts an "all association" Championship elimination tournament.
Currently this involves senior teams in Year 10-12 Basketball, Netball and Soccer. A junior Year 7-9 Basketball championship also runs concurrently with the senior basketball.
ACC member schools can nominate teams through their sub-association group or via geographic based Wildcard Pools (north or south of the Swan River) or One Day Carnivals pools. Following the completion of the group/pool stage the Championship then moves into the elimination finals with the best teams within each sport taking part.
The ACC Championship is the pinnacle of competitive interschool sport within the association.
