Following Saturday's third-straight flag, Oliver's prediction has rang true.

The Cats are the modern day power of the HDFL, having won 49 of 54 games in their three premiership years of 2013, 2012 and 2011, while they also made the grand final in 2010, but were beaten by Heathcote.

"It's pretty surreal at the moment," Oliver said.

"I'm really pleased with our input today... into another grand final today and we were as hungry as to get it, and I think that showed.

“We’ve worked extremely hard and everyone who has won a premiership will understand how hard they are to win.

"But to win three in a row... we’ve got clubs every week trying to hunt us down, but these boys stand up and love the challenge of clubs trying to knock them off.

“And they’re good enough to stand up to it.”

As well as thriving on the challenge of being the hunted each week, Oliver says the tightness of the playing group has been integral in the Cats' sustained success.

“The club is very strong and it’s a tight-knit community. If you’re not in the football club then you’re probably not in the community,” Oliver said.

“They’re just a great bunch of blokes to coach and I’ve loved every minute of it.”

The tightness of the playing group is typified by 12 of Saturday's premiership 22 having come through the club’s junior ranks.

The Cats showed their class in the second half on Saturday to kick away after half-time.

After leading by 12 points at half-time, the Cats booted nine goals to two after the main break to cruise to a 58-point victory.

They swamped the Hawks with their pressure all game, while their use of the ball was first-class – none better than best on ground Adrian Dohnt, who barely wasted one of his 40-odd possessions.

While Dohnt was the clear standout on the ground, the Cats' better players also included defender Carl Treacy, classy forward Jarrod Bacon (four goals), Jesse Collins, who was outstanding in his run-with role on Ryan Semmel, Lachlan Collins (five second-half goals) and wingman Nathan Bacon.

Saturday's grand final brings to an end Oliver's four-year stint as coach.

The key forward finishes as a three-time premiership coach, with Dohnt to take over from next season.

"It (the three premierships) isn't something that has really sunk in yet.

"But I'm sure it will after a few days and weeks," Oliver said.

Oliver expects the bulk of the Cats' group to stick together next year in pursuit of premiership number four.

"There's no reason why we can't have another crack at it again," Oliver said.

As well as the senior premiership, the Cats also claimed the reserves flag on Saturday, belting White Hills by 71 points.
