When Callum McFadden popped through his first goal, it was the sign of things to come - for both himself and the team.

McFadden was in rare touch, finishing the game with seven goals in a man of the match performance - as the Kangaroos thrashed Wollongong Bulldogs to win this year's AFL South Coast premiership.

Desire was never going to be an issue for Figtree, who had felt the pain of a grand final loss at North Dalton Park last September. But on Saturday, that was all washed away as the Kangaroos recorded a 19.15 (129) to 3.7 (25) victory over a shell-shocked Dogs outfit.

It capped a hat-trick of senior premierships for Figtree, after their Men's Division One and Division Two teams also won their grand finals.

"It's massive, mate. Last year was such a hard day for a lot of us here, especially for me too," McFadden told the Mercury.

"To see what we've done this year, in all three grades and everyone's part of it, it's great to see. Everyone here is a winner today. I was a Figtree junior maybe 10 years ago and we didn't even have a first grade team four years ago. For all three teams to win all three grades, it's great to see."

McFadden said it was terrific to score his first goal after 12 seconds, with his second coming over a minute later.

"It was a good way to start the day, knocking over the first two," he said.

"But I knew the job wasn't over and it was great to finish the game so strong."

Kangaroos coach Will Ryan said it was a special feeling to create club history on Saturday.

"It feels pretty good, our first one ever. We're obviously very happy," he said.

"We set ourselves a task this year and we came in ready to go, and we executed and the boys knew what to do. It feels very much like redemption. All 22 of them needed to get the job done, and they did it."

Figtree were on song from the outset.

From the first bounce, ruckman Leroy Veerhuis tapped the ball down to Kyle Veerhuis, who drove the ball deep into attack. From a pack situation, the ball fell into the hands of McFadden who kicked truly. Less than 90 seconds later, McFadden had his second goal.

It was all Figtree during the early stages and they continued to press hard, with Constable snapping truly from 40 metres out to kick his side's third goal.

The Bulldogs finally started to find their groove, winning some ball out of the middle and launching into attack. However, again it was the Roos who hit the scoreboard, with Constable kicking his second goal.

The only thing that stopped Figtree from completely blowing the Dogs out of the water in the first was inaccuracy in front of goals, kicking seven behinds.

With less than one minute remaining, Bulldog Louis Beard nearly took the mark of the century in the centre of the ground, however, he couldn't hold on to the ball.

The miss would prove costly, as Figtree took possession and chipped the ball into the forward line to an unmarked Nicholas Hay.

Hay kicked the goal with seconds as the siren sound to give Figtree a 5.7 (37) to 0.0 (0) lead at quarter time.

The Bulldogs needed to start the second well, but again it was the Roos who hit the scoreboard early through Constable.

The Dogs continued to scrap hard and had a good chance to score, however, Sam Price couldn't convert his opportunity.

Figtree made them pay not long after, with McFadden snapping truly to boot his third goal of the game and give his side a 50-point advantage.

But the Bulldogs refused to give in. After a couple of Figtree misses, it was the Dogs who booted the next goal through Jonte Schmetzer.

While the momentum was slowly swinging back towards the Dogs, again it was Figtree who managed to hit the scoreboard again - this time via Kyle Veerhuis.

With about two-and-half minutes left, Figtree drove the dagger into their opposition's hearts. McFadden found himself in space in the forward line, selflessly handballing over the top to an unmarked Constable who kicked the goal.

The Kangaroos led by 9.11 (65) to 1.3 (9) at half time.

Once again, it was the Roos who started the third quarter full of intent, with McFadden booting his fourth goal.

McFadden continued to be a dangerous figure up forward, kicking another goal, while Aidan Cook also scored to give their side a 12-goal advantage.

Finally, the Dogs were able to break the shackles with about five minutes left in the quarter when Braydn Beesley kicked truly. However, their joy was short lived as the Kangaroos replied almost immediately through McFadden.

McFadden then kicked truly again - his seventh of the game - minutes later as the Roos continued to pile on the pain.

Figtree led by 14.14 (98) to 2.4 (16) at three-quarter time.

It was a quiet start to the last quarter, with neither side finding a goal in the opening five minutes.

Bentley Murphy was finally able to break the Dogs' goal-scoring drought, but their joy was short lived as Hay replied almost immediately.

And despite their healthy lead, the Kangaroos continued to press hard and were rewarded when Kyle Veerhuis snagged a nice goal with about 11 minutes remaining.

Goals to Darcy Hennessy and Mitchell Daly saw the Kangaroos push their lead out to 98 points late in the game. A late goal by Hay rounded out the 104-point victory for Figtree.

It was a result that left Bulldogs coach Aidan Leishman shaking his head, but full of praise for the opposition.

"They just came to play. Every time we started to claw our way back into the game, they seemed to have another gear and kept rising, and we couldn't match them," he said.

"Those two centre clearances, and two goals, it just put us on the back foot from the get-go and we were playing catch up all day. We couldn't even seem to get a lucky bounce our way today. But I just said to the boys, we've to now re-set and re-tool, and have another crack next year.

"They [Figtree] showed they were a class above everyone else in this league and the standard that you have to get to to win this thing. We'll go back to the drawing board and try to improve. But credit to Figtree, they were probably fueled by their grand final loss last year. And maybe we can now do the same. They just wanted it more today, from the get-go, they were first to the footy and ran in numbers. Every time we started to get roll on, they came back stronger and harder, and we just couldn't match it."
