The Wallabies have lost another couple of players to injury with wingers Joe Tomane and Chris Feauai-Sautia both ruled out of Saturday night's Bledisloe Cup clash with the All Blacks in Dunedin.
Australia have already lost inside centre and goalkicker Christian Lealiifano and in-form flanker Scott Fardy for the dead rubber.
The loss of Tomane is the most significant for coach Ewen McKenzie, after he starred in Australia's last-start demolition of Argentina, scoring a try and setting up another.
Waratahs winger Peter Betham has been added to the Wallabies' 24-man squad, but Nick Cummins shapes as the frontrunner to replace Tomane.
The other option is to move Israel Folau to wing and replace him at fullback by Bernard Foley.
Matt Toomua is set to replace Lealiifano at No.12 and Ben McCalman tipped to come in for Fardy.
The team will be named tomorrow.
