Bernard Foley will return to flyhalf for his first Test start since the second Bledisloe Cup Test in Auckland back in August with Kurtley Beale shifting to inside centre.
Matt Toomua has been named on an extended bench for his last game before returning to club duties in England at the conclusion of the international window.
The Leicester playmaker is ineligible for the third Bledisloe Cup Test in Japan but may be selected for the upcoming Spring Tour of Wales, Italy and England.
Hooker Tolu Latu has also earned a re-call for a spot amongst the reserves, in what could be his first Test since the opening Bledisloe Cup clash in Sydney.

The extended bench will be trimmed to eight on Friday after the team travels to Salta, in Argentina’s north-west, from their current base in Buenos Aires.
Argentina won the last meeting between the two sides 23-19 on the Gold Coast last month, to break a five-match win streak for Australia.
Saturday’s clash in Salta will also be the first Test between the Wallabies and Pumas at Padre Ernesto Maltearena Stadium which sits 1,152 metres above sea level.
