The Redbacks were the first through to the decider with their 51-point preliminary final win over Trentham, 11.15 (81) to 3.12 (30), at Princes Park on Saturday.

The victory booked Carisbrook its sixth-straight grand final berth and set up the chance to win a third flag in a row having beaten Natte Bealiba (72 points) and Navarre (20) in the decider the past two years.

The Saints stuck with the Redbacks for the first half and only trailed by seven points at the main break after they kept Carisbrook scoreless during the second term.

But the Redbacks put the foot down with eight goals to one after half-time and are now 23-0 from their past 23 encounters with the Saints.

Malcolm Niblett and Harrison Butler (two goals) were Carisbrook's best, while Trentham's star midfielder Joel Cowan battled hard for his side and will start as one of the favourites for Monday night's Berry Powell Medal.

On Sunday, Natte Bealiba beat Lexton by 34 points on the back of a dominant first quarter.

The Swans burst out of the blocks, kicking 6.5 to 1.0 in the opening term.

After that it was eight goals apiece as the Swans won 14.8 (92) to 9.4 (58).

The standouts for the Swans were headed by Zac East, Jye Mortlock (two goals) and Lachlan Cameron.

Todd Curran and Oliver Hayes played well for Lexton.

The grand final will be played next Saturday at Maryborough's Princes Park.
