Losing grand finalists in Sydney last year and forced to play Sunday's semi-final in NSW due to COVID, the minor premiers learned on Wednesday that they can host the showpiece decider at AAMI Park with a 50 per cent capacity of 15,000.

"It's a big advantage," said Atkinson, who was in the City team beaten 1-0 after extra time in last year's decider.

"Last year we went into a hub and weren't allowed to play in front of our fans and in the semi this year we had to play in Sydney, so this is something we deserve after the season we've had and a chance for our fans to enjoy the game.

"Just looking back to the game where we won the league against Central Coast, we had a really good turnout which helped when we were under the pump.

"The fans were really our 12^th man that day and helped us get through."

One of just a handful of Tasmanians to grace the national soccer competition, Launceston-born Atkinson said it had been a long-held dream to reach such a stage.

"Coming from little old Tassie it's been a long journey and I've been living away from home since I was 14 but this makes it all worthwhile and this year my family can come to the grand final and that's great for them to experience.

"This is what you dream of as a footballer. There's no better stage in Australia than an A-League Grand Final and I'm only 22 so it can only benefit me moving forward.

"I remember watching Sydney v Melbourne Victory at AAMI when (Leigh) Broxham scored (2015) and Perth v Sydney two years ago with nearly 60,000 at Optus Stadium. Nothing beats that."

Recovered from the injury which nearly ended his season, the Riverside Olympic product played an advanced role in the 2-0 semi-final win over Macarthur.

"No issues with the hamstring. That was my first 90 minutes in 12 weeks but will only benefit me for the final and it's good to be back.

"I'm playing in a slightly different position due to our injuries, on the right wing. I started out there and I enjoy it. I'm attacking-minded as a full-back anyway and this just gives me a bit more chance to get forward."

With three titles and three minor premierships in the last four years, Sydney has the most successful record in the A-League. But Atkinson believes his side is ready.

"Last year definitely benefitted us and we've gone one better this year by winning the league. Sydney just know how to win these games. Rostyn Griffiths said in our rooms last year, they have done this for about five years and just have that experience. They are an attacking threat with their big front four but we have both lost players to the Socceroos and we've beaten them this season and also drew at their place."

After Sunday, thoughts will turn to Tuesday's announcement of the Olyroos squad for the Olympics with Atkinson among the young guns in the frame.

"Everyone is staying very tight-lipped about the Olympics but the grand final is another chance to prove myself and next week we should know something," he added.
