ADHS holds annual sporting carnivals for swimming, cross country and athletics. These whole school events emphasise fun and encourage everyone to participate. The events held at these carnivals allow students to qualify for subsequent Zone and ACT level carnivals. Students that are eligible for the 12 years and under need to follow a different pathway only if they wish to be considered for an ACT representative team. This information is given to this group individually.
