Dunn, 43, will stand down at the end of the Hampden league season.

He met with Kangaroos football director Craig Pertzel on Tuesday and told the players of the decision at training that night.

"I've really enjoyed the experience and the Hampden league is a great league to be involved with and the other coaches have been great to coach against," Dunn said.

"They are very collaborative and there's guys I have enjoyed bouncing ideas off and learning from."

Dunn said his children Phoebe, 12, and Jobe, 9, wanted him to stay on as coach but he felt the time was right to move on.

"I am comfortable with the decision, I have been thinking about it for the last six weeks and Craig and I were due to catch up and talk and we were on a similar page," he said.

"I will definitely be around the club (next year) in some capacity. I don't know what it will be yet, it depends on the new coach but I am keen to be involved."

Dunn, who works in public service, said coaching called for 100 per cent commitment.

"You spend a lot of time on it that people don't see - the preparation, the organisation and the emotional attachment," he said.

"You ride every wave with the players. Mentally it's very challenging to try and stay on top of all that and the mental challenge is what got me in the end."

Dunn has the opportunity to finish his tenure on a high with the 4-7 Roos still in finals contention with seven rounds remaining, battling South Warrnambool (6-5) and Camperdown (4-7) for fifth spot.

The Kangaroos - the result of a merger between former Western Border league clubs Hamilton Imperials and Hamilton Magpies - are yet to see September action since joining the Hampden league in 2013.

"While finals are still alive that will be our goal," he said.

Dunn coached South West District league club Coleraine for three years and had a season helping NAB League club GWV Rebels before signing on at the Kangaroos.

"I am absolutely stoked to get an opportunity to coach the club," he said.

"It had a very young list in my first two years and seeing those players develop into good senior players has been encouraging for me."

Pertzel said the club would be proactive and expansive with its search.

"We want to play finals footy and want success for our club," he said.

"We'll look far and wide and within to entice the best guy to coach the football club next year."

Pertzel and Dunn met on Tuesday and "agreed amicably" he would step down.

"He's been there four years and we felt he'd done as much as he can with the group and it's time for a fresh voice," he said.

Pertzel paid credit to Dunn whose imprint extends beyond the senior side.

"He's a life member of the club and we think he's done a terrific job to the develop the boys and the club is certainly in a better place than when he started," he said.

Hamilton's decision follows Terang Mortlake's announcement Michael Sargeant would stand down at season's end after three years in charge.
