He has gone from the Jack of all trades to the mastering of one, and Gold Coast is the beneficiary.

Last year, Jack Lukosius spent his first AFL season getting a taste of all positions available on the field. He started as a lead-up key forward, had a taste of things on the wing using his athleticism, and finished as a defender.

As a learning experience, 2019 offered Lukosius plenty. But he was also keen to settle into one role and see how he fared.

"This year I trained all pre-season down back and really simplified the game, and it's got my really confident in my role," Lukosius told AFL.com.au.

"I think it's worked out pretty well. Obviously I learnt a lot seeing the game behind the ball and in front of it last year, and I'm feeling really comfortable in defence at the moment and it's really catapulted me into this season.

"I am definitely feeling comfortable there at the moment but I'm happy to play wherever 'Dewy' (Suns coach Stuart Dew) puts my magnet. I'm open to going forward at some point as well."

Lukosius has enjoyed a strong start to season as the Suns have surged to three straight wins.

The 19-year-old has averaged 15 disposals and four rebound-50s a game across the interrupted season, and last week floated forward to slot a brilliant goal from the boundary line.

Lukosius was drafted as a forward with pick No.2 in the 2019 intake alongside talented top-end Suns Ben King and the yet-to-debut Izak Rankine.

The Suns are sitting in second position on the ladder after strong wins over West Coast, Adelaide and Fremantle, but had also posted three wins from their first four games last year before losing the remaining 18 matches of 2019.

Lukosius, who played all bar one of those games last season, said the Suns' brand was more sustainable this time around.

"That's the challenge, we've been here before. But I feel like what we're bringing in contest and pressure and those type of things is going to measure up," he said.

"Not a whole lot has changed with our game style but I feel like we've been a lot better at stopping momentum.

"When other teams get on a run we've been able to stop it at two or three goals and last year sometimes that got away from us. That's been a big thing for the group and then when we've got momentum just making the most of it as well."

The Suns face their biggest challenge so far this season when they travel to play Geelong at GMHBA Stadium on Saturday as the Cats celebrate the milestones of champion pair Gary Ablett (350th game) and Joel Selwood (300th).

Lukosius says the Suns have used their round one drubbing at the hands of Port Adelaide to kickstart their run since football returned.

"It sat in our stomach for the whole two months we were at home so to come back in the shape we did as a pretty young group and start off with a few wins has been super," he said.
