Every season the AAGPS/RASHCKE Cup (all AAGPS schools compete) is played (formerly in a one-week before Round 1, in a 2-day round robin formatted competition) over the trial rounds, with the schools being separated into two pools, with the winner of each group playing each other in the final. This cup is the 2nd most prestigious accolade from a season. In near consecutive seasons of 2013, 2014, 2015, 2017, 2018 Saint Ignatius College Riverview have made the final, in which they have been victorious 4 times (13, 15, 17, 18).

The season begins in Term 4, where teams will play trial matches against a mix of AAGPS, ISA, and CAS teams, including 3 rounds of Raschke Cup/Yeend Shield, where a pre-season winner will be crowned.

Term 1 begins the competition games where schools play each other every Saturday, 10am for 2nd V and 11:15am for 1st V. If a team is able to win 7 games they will be crowned Undefeated Champions and earn the outright AAGPS title.^[4]
