Perryman is part of the strong Riverina contingent looking to deliver Greater Western Sydney their first AFL premiership on Saturday.

He can't wait for his moment against Richmond.

"I remember as a kid growing up you always wanted to be out on the MCG on the last day in September," Perryman said. "I've had a bit of premiership success back at 'Gullie and this is just another level up.

"I just can't wait to run out with the boys on Saturday."

Perryman played alongside older Nick when the Demons scored back-to-back Riverina League crowns in 2014 and 2015.

He hasn't played in a grand final since. Let alone a game of this magnitude.

However the 20-year-old is excited for what lies ahead in his third season with the Giants.

"It's unreal all the boys are up and about and pretty excited," Perryman said.

"It hasn't really sunk in to be honest but I just can't wait to get down to Melbourne, do the build up and really lap it up."

Perryman put in one of his best performances to help the Giants break through their preliminary final barrier and set up a showdown with Richmond.

He hasn't missed a game since recovering from a punctured lung in round nine with his toughness shining through after a nasty incident in the opening round of the season.

Growing up a Collingwood supporter, there was plenty of nervous moments up against some of his childhood idols.

However when the final siren sounded and the Giants were still four points clear it was pure euphoria.

"It was a pretty up and down game and midway through the last quarter we probably thought we had them but they made a fightback," Perryman said.

"They kept kicking inside their forward 50 and every time they kicked it in I thought we were done so when the siren sounded it was absolutely unreal."

Now he's looking to embrace the grand final experience.

"As much as it is a massive game it is just another game of footy really," Perryman said.

"You want to take a relaxed approach and just enjoy the moment as it may never happen again."

GWS have come through two tight finals in the past two weeks to earn their spot in their first grand final.

Perryman believes that will help them on Saturday.

"It's pretty obvious it will be intense but we've played in three cut throat finals in the last three finals," he said.

"We know what they are going to bring.

"They are a great side the Tigers and will be that hard to beat but we have some good momentum at the moment and we just want to keep riding that and see what happens on Saturday."
