Australia have left out pacemen Peter Siddle and Ben Hilfenhaus for the third and final Test against South Africa in Perth.
The pair are fatigued from their epic exertions against the Proteas in Adelaide so Mitchell Johnson and Josh Hazlewood are likely to spearhead Australia's pace attack.
Shane Watson is guaranteed to return to the side in place of Rob Quincey, who bagged a pair in Adelaide, for Ricky Ponting's farewell Test.
An Australia win will see them leapfrog their opponents at the top of the ICC Test rankings.
South Africa may promote Faf du Plessis up the batting order following his heroic century in Adelaide which earned the tourists an unlikely draw.
The Proteas will make a late decision on whether to use Jacques Kallis as a specialist batsman with a hamstring injury already ruling out any bowling role for the all-rounder.
Ryan McLaren is the other all-round option for the tourists while Vernon Philander returns after a back complaint kept him out of the Adelaide Test and spinner Robin Peterson is set to take Imran Tahir's spot.
