DIMBOOLA sealed the minor premiership on Saturday after a dominant 152-point win over Ararat at Dimboola Recreation Reserve.
It was another first-class performance from the rampant Roos, who showed they would be a serious challenger to 10-time reigning premier Horsham.
An undermanned Rats outfit, missing seven of their best 21 players, had no answers for Dimboola stars Ash Clugston, Peter MacFarlane, Lachie Exell and Andrew Seers.
Clugston finished with a game-high seven goals, with MacFarlane, five, and Exell, four, also punishing Ararat on the scoreboard.
Dimboola captain Al McKinnon said it was a good team effort, with everyone playing their role.
"I'm really happy with how the boys went," he said.
"We've just been working on our consistent four-quarter efforts all year and we hadn't really nailed it until this weekend."
McKinnon highlighted the performances of the Magee brothers Tom and Matt and Daniel Baker, who all provided plenty of run across half-back.
Ararat co-coach David Hosking said it was a hard day at the office, with nothing going to plan from the get-go.
"The ball was bounced, Dimboola got in front and they stayed there," he said.
"Dimboola was very good and I think they've improved since last time we played them."
Hosking said the Roos were the team to beat in September.
Wingman Brendon Lovell was Ararat's best, while on-baller Jake Williamson was a major contributor.
Brady Miller was solid in defence, Harry Ganley kicked three goals and Brody Taylor worked hard on debut.
Dimboola's seniors and reserves sides have a bye at the weekend after finishing on top of the ladder.
The Roos' seniors will play the winner of Saturday's qualifying final between Horsham and Warrack Eagles.
