North defender Jamie Macmillan says his side can't wait for finals football to get underway.

North Melbourne completed a light training session at Adelaide Oval on Friday afternoon in preparation for Saturday night's elimination final with Adelaide.

The Kangaroos trained for about 45 minutes before signing autographs for about 600 supporters.

Kangaroos defender Jamie Macmillan told reporters that the Western Bulldogs' upset of West Coast showed anything is possible in the finals.

"The result last night has probably surprised a few, so anything can happen," Macmillan said.

"I was watching that game and I saw the odds came up for our game so we're obviously the underdogs.

"You don't really draw a whole lot on that sort of stuff, but anything can happen in finals."

The Adelaide Oval playing surface is in immaculate condition despite a heavy storm hitting Adelaide on Thursday night.

A capacity crowd of close to 50,000 is expected, with about 1800 tickets remaining on sale on Friday afternoon.

Macmillan said the Kangaroos needed to make a fast start to take the crowd out of the game.

"Hopefully we can kick 10 goals in the first and silence them," he said optimistically.

"We played them in the middle of the year just before our bye.

"When the Crows are up and going, the crowd is certainly loud and they are almost another man on the field.

"We need to get on top early and silence them."
