The All Blacks will almost certainly name their strongest line-up against the Wallabies for a test in front of a crowd of more than 60,000 at a sold-out stadium.
Brodie Retallick won't feature until the World Cup at the earliest due to his dislocated shoulder, and Sonny Bill Williams will drop to the Mitre 10 Cup where he will probably play two games for Counties Manukau – possibly a pre-season match in Katikati on Saturday and the round one fixture against Taranaki at Pukekohe - in order to improve his match fitness.
But elsewhere Hansen will go with his big guns and that will provide further evidence of his thinking for the first World Cup pool game against the Springboks and following knockout matches.
Asked what he expected from the Wallabies, who lost their first Rugby Championship game against the Springboks in South Africa before edging the Pumas 16-10 in Brisbane at the weekend, he replied:"A torrid battle. We always have great games against them - it will be a fast game."
With Richie Mo'unga and Beauden Barrett finally finding their rhythm just after halftime at Westpac Stadium, the pace at which the All Blacks played was noticeably high. The Boks were stretched to breaking point. More of the same but without the handling errors will be the plan in Perth.
"Sometimes when you're trying new things you're having to think about how you're doing them," Hansen said in defence of his players, and in particular his forwards, a day after the 16-16 draw. "In a high-speed game when there's a high-speed defensive line coming at you, you haven't got time to think about it. You have to be instinctive.
"When you slow down to think about it some of your motor skills go. Sometimes your lungs go pretty quick too and then your skills go. Some of the big boys last night really felt the pinch of the speed of the game because we asked them to do a lot."
