A preliminary final berth is on offer for the victor, with the season to come crashing to an end for the loser.

Horsham Saints have beaten the Roos twice this season, with the most recent win coming in the final home and away match.

Dimboola coach Gary Davidson knows his side faces a big challenge but he saw positives signs in their elimination final win against Minyip-Murtoa last week.

"I thought right across the board we were good last week," he said.

"But we have to step it up another level again now."

The Roos forwards have struggled against the Saints this season, averaging nine goals.

They have averaged more than 16 goals a game against the other seven teams in the competition.

"How we use the ball going forward will be really important," Davidson said.

"We've got good forwards and we're capable of kicking good scores; we'll be relying on our midfield to win the ball and present it to our forwards well."

In a blow for the Roos, they'll be without classy midfielder Al McKinnon, who is overseas with work commitments.

Horsham Saints coach Brendan Broadbent said his side needed to bounce back strongly after a loss to Warrack Eagles in the qualifying final.

"It was disappointing not to win last week now we've got to find our form again," he said.

"Last week we only played two good quarters and a poor second quarter really let us down.

"We have a young side and we struggled to maintain the intensity that is needed."

Broadbent said handling pressure was a focus on the training track this week.

"We need to work as a team," he said.

Broadbent said a winning record against the Roos meant little.

"They're a strong, experienced side. It's not an easy ask," he said.

Bernard Ward is in contention for a return for the Saints.
