Wales head coach Warren Gatland has disregarded his side's seven-year losing streak against Australia ahead of Saturday's game.
The Wallabies haven't lost to Wales since 2008 despite a number of close matches between the sides since then, especially in 2012 when Kurtley Beale's 79th minute try snatched victory in Cardiff.
Gatland pointed to his side's wins over South Africa last year and their comeback against England as reasons to be positive.
"We haven't spoken about it at all. The last five times there has been a score in it," Gatland said.
"We’ve been ahead in games and we haven’t been able to finish it off. You learn from those experiences and I’d like to think we have demonstrated that in the big games.
"In November against South Africa, we closed that game down, and coming from behind against England in the last 20 minutes."
Outlining his interesting team selection – which features Gareth Anscombe at full-back and Sam Warburton shifted to six with Justin Tipuric in the back-row – Gatland said that extra caution had been taken on Dan Lydiate who misses out at Twickenham.
"[Lydiate] got a serious knock on the eye last week and he's quite sore," Gatland revealed.
"I spoke to him on Monday and said if we were playing in the final then I would have picked him this week. The next day he understood the decision. He was fit for this weekend.
"Justin (Tipuric) deserves an opportunity. He’s been absolutely outstanding in the warm-up games. It gives us options and the balance we’ve had. It’s horses for courses and it’s about matching them at the breakdown.
"It will be a fierce contest. We’ve been successful in the past and the job Sam (Warburton) did in the second test for the Lions in 2013, in the way that he controlled things at the breakdown."
