Whether he plays at fullback or centre - and he's adamant he still doesn't know which one it will be - Israel Folau's main task on Saturday will be finding holes in the All Blacks midfield.
The All Blacks, whether they agree or not, will be viewed as being vulnerable in the midfield. It's the one area where they still don't have a good feel for their preferred combination and didn't quite develop as much as they wanted against Wales in June.
From a Wallaby perspective it's the first place they will presumably look to jam in the crow bar and see what they can exploit. The last time they played the All Blacks, they faced Ma'a Nonu and Conrad Smith, with Sonny Bill Williams coming off the bench at half-time to replace the latter.
On Saturday, it will most likely be Ryan Crotty in the No 12 jersey with either George Moala or Malakai Fekitoa at centre - a different scenario entirely in terms of threat, experience and influence.
The Wallabies, who have the options of introducing the massively experienced Matt Giteau at second-five, may feel they have the players and skills to build a range of clever attacking ploys to pull the All Blacks out of shape and unsettle a young and inexperienced midfield pairing.
