Australia coach Michael Cheika insists there is no pressure on his team ahead of the Rugby World Cup final against New Zealand.

The Wallabies and All Blacks do battle at Twickenham on Saturday looking to win the Webb Ellis Cup for the third time.

Despite the occasion, Cheika played down the expectations and pressure surrounding his team.

"It's irrelevant. I don't feel like there's any pressure," he told a news conference.

"People like to talk about the whole pressure thing, but for me, we love playing the game and if the game was amateur still, everyone would still be playing it.

"There may not be as many journalists at this press conference, but everyone would still be playing because we love the game.

"You've just got to do your absolute best. The only time you feel pressure is if you're not prepared as you possibly can be.

"So let's prepare the best we can and go out there and do our absolute best and, I've said it before many times, the cards will fall where they fall."

Cheika said he had tried his best not to change the Wallabies' preparations ahead of the decider.

The 48-year-old wants to avoid thinking about the significance of the occasion.

"We're just doing what we try to do, to be as best prepared as possible," Cheika said.

"Every day, prepare certain things and just keep adding the next day's and the next day's things together. So we can be ready to play our best on Saturday.

"If I start thinking this is a massive game and start doing things differently, I'm not looking after my team properly.

"I just want to make sure that they're very well prepared, best they can, and then they'll get the chance to put everything we've done out on the field."
