Morale among the North playing group is high and silencing the West Coast crowd in the first quarter is crucial, defender Sam Wright says.

The Roos will take part in back-to-back preliminary finals when they travel to Perth to face the Eagles at Domain Stadium this Saturday night.

Wright said the club would enter the game determined to go a step further after last year's preliminary final exit.

"We got smashed in the prelim which we were really disappointed about and obviously to get there this year when a lot of people have written us off would be good, and that's motivation in itself," Wright told NMFC.com.au on Tuesday.

"We just feel like all our structures and organisation at the minute is coming along well and we're all playing together as a team, so if we can keep that going, we're a good chance."

The Roos travelled to the west to face the Eagles in an elimination final in 2012, but were comprehensively beaten to the tune of 96 points.

In that game, the Eagles set up the victory with seven goals to nil in the opening quarter.

Wright said silencing the hostile home crowd from the opening bounce would help avoid a repeat of the big loss.

"2012 was the hardest it's been for us, obviously we got smashed over there by them and the crowd were up and about early, especially in the first quarter," Wright said.

"If you can stop that at the start, it goes a long way to silencing them a little bit."

More recently, the Roos last met the Eagles in round 10 at Blundstone Arena.

Wright said the side would not read too much into that win given the blustery conditions in Hobart on that particular day.

"We battled hard, kicking against the breeze in the last quarter and to come back and win was good," he said.

"In saying that, the weather was ridiculous so you can't take too much out of that, like stoppage structures were obviously different to accommodate the weather, so (we're) not looking into that (game) too much."
