The Roos defeated Geelong by six points at the MCG on Friday night, surviving a frantic late charge by the Cats to earn their first preliminary final berth in seven years. 

Before Friday's thrilling victory, North's 12-point comeback win over Essendon in last Saturday's second elimination final was its first finals win since 2007.

But Scott said the Roos still had unfinished business in this year's finals series and would be ready to produce their absolute best against the Swans.

"We're not done yet," Scott said.

"We're not complacent, we're not happy to be where we are. We're focused on the task at hand next Friday."

Scott said his players would also head in the clash at ANZ Stadium chock-full of confidence, knowing that they were undefeated against the other four teams remaining in this year's premiership race.

Although North has played each of those teams only once this season, it emerged with the four points on each occasion, defeating Port Adelaide (Etihad Stadium) in round three, the Swans (SCG) in round four, Fremantle (Patersons Stadium) in round six and Hawthorn (Etihad Stadium) in round 16.

"There are five teams left contending, and we're the only ones who have beaten the other four. And none of them have beaten us, so we go in with supreme confidence and we're still in really good shape," Scott said. 

"Geelong had three more scoring shots in the last quarter so it's not as if they absolutely steamrolled us, and we played our best footy of the year. 

"So we're going in with good confidence against the really good sides and we're playing our best footy when it matters."

Scott said he would not spend too much time analysing North's round four victory over the Swans, nor would he have his players train on ANZ Stadium before next Friday night's game. 

Just five players on the Roos' list have played at the venue before, with North's only game at Homebush coming in a 2008 elimination final defeat.

North has some concerns ahead of next Friday night's game, with Brent Harvey involved in an incident that left Geelong skipper Joel Selwood with a cut above his eye, and Jamie Macmillan substituted from the match in the third quarter with a hamstring injury.

"People won't believe me, but I haven't seen it, I haven't looked at it, haven't followed it up," Scott said of Harvey' second-quarter clash with Selwood.

"So I'll let that all play out. I've just told 'Boomer' to go about his recovery and not worry about it."

Scott said North would not know the extent of Macmillan's injury until he had scans.

"But suffice to say he was too tight and too sore to come back on," Scott said. 

The North coach said key defender Lachlan Hansen (hip) would be "pretty close" to being available for selection against the Swans, along with Leigh Adams (concussion).

But Scott was confident that if Hansen did not come up, North's defence, led by Scott Thompson, Nathan Grima and Michael Firrito, could handle Swan talls Lance Franklin, Kurt Tippett, Sam Reid and Adam Goodes.
