Quade Cooper is set to be employed as the Wallabies' X-factor off the bench as Michael Cheika turns once again to his World Cup finalists in his latest bid to stop the All Blacks juggernaut.
Cheika is tipped to retain Bernard Foley as five-eighth despite his lacklustre series against England rather than pitchfork the mercurial Cooper into another Bledisloe Cup starting role on Saturday.
Cooper instead shapes as a second-half "finisher", charged with offering Kurtley Beale-like spark with the match on the line at ANZ Stadium.
Cheika is also expected to resist calls to move Israel Folau into the attacking front line, though newfound vulnerability in the All Blacks centres is giving the coach further food for thought.
The standout form of first-year Wallaby Dane Haylett-Petty in the 3-0 June series loss to England is also causing headaches.
While keeping Folau at fullback would allow the Wallabies to reunite the World Cup centre pairing of Giteau and Tevita Kuridrani, accommodating Adam Ashley-Cooper on one wing means Cheika would have to also relegate either Haylett-Petty or newly appointed vice-captain Rob Horne.
Cheika will name his match-day 23 on Thursday and admits the return of Giteau, Ashley-Cooper, Drew Mitchell and halfback Will Genia from France for Rugby Championship duties has made selection time difficult.
"There's four backs straight back in that are competing for spots and then you've got guys like Lopeti Timani who's really impressed," he said.
"Adam Coleman, now that he's had a bit of experience in June, Dane Haylett-Petty obviously had a really good series in June. (Samu) Kerevi.
"So some of those young guys we blooded in June are competing for spots again and that's a bit of our strategy: bring the guys back in who have got the experience, (get) push from the youth that want to break into the team and squeeze everyone in the middle.
"There's still plenty of time to go on that strategy, but it's starting to happen."
Cheika said he'd have no hesitation breaking up the NSW halves duo of Nick Phipps and Foley, who helped pilot Australia to a 27-19 victory over New Zealand in Bledisloe Cup I in Sydney last year, to pair either with Cooper or Genia.
But he is keeping his cards close to his chest.
(Cooper's) definitely got X-factor, there's no doubt about that," Cheika said.
"There's areas of his game he's really been working hard to improve on and (we're) really, really pleased with him since he's returned into training.
"(He has a) really good work ethic and understands where he wants to improve. He's giving us that in training. We need to be able to turn that into match action."
