The Power's faith in juniors is working wonders on the eve of their fifth-consecutive Warrnambool and District league finals campaign.

Several recent junior graduates - including Luke Justin, Nick Hoare, Bailey Kemp, Brad Lucas, Luke McConnell and Henry Kenna - played key roles in the Power's 79-point thumping of Merrivale on Saturday.

Kolora-Noorat secured the minor premiership and a week-long break in the rout.

Walsh, a first-year coach, is backing his young charges to maintain their form as the club pursues its second premiership in three seasons.

"We think our strength is our evenness, and the young kids have been as important as anything in that," he said.

"It's pretty exciting and we're confident they can perform under pressure.

"As a coach, I'll keep backing them to take the game on and to play to their strengths."

Walsh revealed his side had taken time to understand the roles of non-playing volunteers over the course of the season.

"We've been talking a lot about club and community this season," he said.

"Obviously a lot of the younger guys have been brought up in (the community) and we have a massive committee of people who put in loads of work, as every club does.

"We want to accept the responsibility of doing our best and we want to keep that front of mind.

"It's easier for younger players when their parents, uncles and aunties are those putting in the work."

The Emmanuel College teacher said his men were still focused on building week-on-week despite their first-place finish.

"We had a meeting (after the Merrivale game) and said while finishing top is good, it means nothing at this stage," Walsh said. "We have the opportunity to get better again in two weeks' time."
