Australia playmaker Matt Giteau has been backed to make a rapid recovery from his Murrayfield agony.
Giteau's poor kicking display against Scotland included a missed conversion during the game's final nerve-tingling seconds.
It meant the Wallabies suffered a 9-8 defeat - their first loss to Scotland since 1982 - and provided the low point of their current European tour.
But Wales coach Warren Gatland, whose team are next up for Giteau and company at the Millennium Stadium on Saturday, does not expect a repeat.
"Matt Giteau is a real competitor," said Gatland.
"Champion players don't tend to back up with poor performances twice in a row, and we are all expecting Matt to play really well on Saturday."
"Knowing the Australian attitude - it doesn't matter whether it is rugby union, cricket, rugby league, whatever - when their backs are to the wall, they tend to respond."
"We expect them to play with a lot of passion."
"It doesn't matter what sport you play against Australia, if you chalk up a victory it means a lot."
Gatland has made a solitary change from the team that beat Argentina 33-16 last weekend, recalling Sale Sharks scrum-half Dwayne Peel instead of Gareth Cooper.
Gatland's selection means that nine players - James Hook, Leigh Halfpenny, Jamie Roberts, Gethin Jenkins, Paul James, Alun-Wyn Jones, Luke Charteris, Andy Powell and skipper Ryan Jones - will have started all four of Wales' autumn Tests.
There are also nine survivors from the starting line-up that accounted for Australia 21-18 a year ago, and the bookmakers have installed Wales as favourites this time around.
But Gatland is refusing to read too much into the dramatic events of Edinburgh four days ago.
"Australia should not have lost - they created so many opportunities," he added.
"It was a great win for Scotland, and you have got to congratulate them, but if that game was played 99 times out of 100 and Australia took their chances, they would have won."
"As a team, Australia have been quite unlucky. They could easily have been playing for a Grand Slam this weekend."
"My experience of Australian teams in the past is when they are in this situation and taken a bit of criticism, there is normally only one way they come out - with all guns blazing."
"Out of the Tri-Nations teams, they are the ones that has played the most rugby. They have a very young, developing side with a lot of potential."
"The test for us is to continue with our progression on Saturday, and be smart in the way we play."
