The Aces join the Central West Wranglers, Coffs Coast Chargers and Lake Mac Attack on Finals Day at the famous ground with the Grand Final under lights on 26 January.
Like the ACT, Coffs Coast and Central West qualify for a second successive season. Lake Mac Attack progress for the first time.
Despite the final round of matches on Sunday being abandoned due to wet weather, the two victories for the Aces in the ACT Pool booked a meeting with the Wranglers in the Thunder Conference Final on Finals Day.
Lake Mac Attack play the Chargers in the Sixers Conference Final.
The Coffs Coast Chargers have qualified for both the Men’s and Women’s T20 Regional Bash Finals.
ACT defeated the Bullets by seven runs on Sunday morning at Phillip Oval before the rain hit and forced the NSW Women’s Regional Bash match, between the same teams, to be abandoned.
Matthew Condon made a solid 56 at the top of the order for the Aces, while Bullets middle order batsman Nathan Brown scored 58 in the narrow loss.
The win added to a seven-wicket victory over the Wagga Wagga Sloggers the previous weekend.
In the other completed match on Sunday, the Sloggers defeated the Murrumbidgee Rangers by 39 runs. Brayden Ambler made 61 from 47 balls at the top of the order for the victors.
