Wallabies coach Les Kiss had named an entirely new forward pack for last weekend’s first test in San Salvador de Jujuy, where they pulled off a narrow 27-21 win, but for Saturday’s game changed only the front row and one of the loose forwards.
Experienced props Angus Bell and Taniela Tupou return with Billy Pollard as hooker.
Rob Valetini moves from No. 8 to the flank to allow for the return of captain Wilson.
Ben Donaldson is named at flyhalf in place of Carter Gordon and will team up with Ryan Lonergan, who stays at scrumhalf as he has in every test this year.
Len Ikitau and Joseph-Aukuso Suaalii start together for the 17th time in the centre pairing while on the left wing Harry Potter is replaced by Filipo Daugunu.
Fullback Tom Wright will mark his 50th cap.
