The Wallabies will look to settle on Pat McCabe's replacement at No.12 as soon as possible as Robbie Deans weighs up the best way to rein in All Blacks powerhouse Sonny Bill Williams.
However, coaching coordinator Tony McGahan says the selection will be more about how Australia want to play in the first two Bledisloe Cup Tests rather than reacting to the dangers of SBW.
Australia are hopeful McCabe (leg stress fracture), James O'Connor (hamstring) and Wycliff Palu (shoulder) will be available for the third Test of the Rugby Championship against the Springboks in Perth on September 8.
But in the meantime, the Wallabies face the enormous task of winning back the Bledisloe for the first time in a decade without two of their key backline stars.
Despite the loss in experience, McGahan says the belief is still there.
"You want to be giving players the opportunity to train there and then be able to settle on that and give the whole team and the individual time ... and confidence," said McGahan from a training camp in Sydney on Thursday.
"Our primary focus will be how we want to play and how we want to defend. We'll look at the make-up of what they're going to come with, but it's what we want to deliver more so than what the opposition want to throw at us."
