At the conclusion of the regular season, the postseason will involve the teams in a two-round structure. Each round will consist of a best-of-three game series between the respective teams. The first-placed team will directly qualify for the championship series, and the second- and third-placed teams will play each other in the preliminary final series, the winner of which will qualify for the second place in the championship series.
Bracket
Qualification
The Sydney Blue Sox were the first team to clinch a postseason berth, when they defeated the Brisbane Bandits in the first game of their second series at Blue Sox Stadium in Sydney, the final series of the regular season. In the second game of the same series the following night, the Blue Sox clinched a home postseason series by beating the Bandits again. The Canberra Cavalry clinched their first ABL postseason berth that same night, when they defeated the Adelaide Bite at Norwood Oval in Adelaide. The win also guaranteed a regular season finish no lower than second, and like the Blue Sox assured the Cavalry oh hosting a home postseason series. The final makeup of the postseason bracket was not determined until the final day of the regular season. The Cavalry guaranteed themselves first place and a place in the championship series when they beat the Bite in their final game. This win also confirmed the Blue Sox would finish in second place and host the preliminary final series. The Perth Heat qualified for the final postseason position when they defeated the Melbourne Aces at Baseball Park in Perth in their final game. The win eliminated the Bandits from contention.
