Brumbies scrumhalf Nic White will start for the Wallabies in Saturday's clash with South Africa in Brisbane, expected to partner last weekend's matchwinner Quade Cooper in the halves.
It will be White's first start for Australia since returning from a knee injury, after coming off the bench during the Wallabies' failed Bledisloe Cup campaign, and last weekend's win over South Africa.
White won a penalty in the dying stages 40m from the Springboks line, before Cooper calmly slotted the penalty goal to give the Wallabies an unlikely win over the world champions.
Ex-Wallaby Elton Flatley lauded Cooper's "tremendous" return to Test rugby, and has thrown up the possibility of James O'Connor as a fullback option for Saturday's match.
Fellow flyhalf O'Connor is fit and available after missing all seven Tests this year, but could find it hard to oust Cooper given his match-winning hand in what was his first Test in more than four years.

But with Tom Banks' hold on the fullback spot starting to wane, former Wallabies playmaker Flatley said Cooper and O'Connor could both be named in the starting 15.
"For Quade to come back and play like he did was tremendous, I didn't think he'd go that well personally," Flatley said.
"Physically he's in fantastic nick and he was rock solid, couldn't fault him.
"That's probably the way the team's looking, there's a spot potentially available there [at fullback for O'Connor].
"If he's fit he's got that experience and know-how to do a job in the 15 jersey."
O'Connor spent the early stages of his Wallabies career at fullback, wing or in the centres.
But he's made the No.10 his own at the Queensland Reds, the same jersey Cooper was frozen out of when coach Brad Thorn arrived in 2018.
Former Wallabies fullback Chris Latham said O'Connor at the back would give the side a triple threat.
"There might be chat of him moving back to fullback," Latham said.
"You need those players that can play unpredictably within a structure."
