Robbie Deans has made four changes to the Wallabies' line-up for Saturday night's Tri Nations Test against South Africa in Perth.
Brumbies lock Mark Chisholm replaces Nathan Sharpe, prop Ben Alexander replaces the benched Al Baxter in the front row while Ryan Cross comes into the centres for the injured Berrick Barnes and Peter Hynes has taken the place of Drew Mitchell on the wing.
Chisholm makes his way back into the Test 15 after just two Sydney club matches for Randwick following a wrist injury during the Super 14.
World No.1 South Africa are unbeaten in three Tri Nations matches this year while Australia is still searching for its first win.
