It seems likely that Kurtley Beale will wear the fly-half jersey for Australia in their upcoming Rugby Championship meeting with South Africa in Pretoria.
Beale, who came under critcism from head coach Robbie Deans earlier in the tournament for poor form, has reportedly shone at 10 during training.
The 23-year-old Rebel is expected to take the spot of the injured Quade Cooper after the Reds pivot was ruled out due to minor knee surgery.
Subsequently, Berrick Barnes will continue at full-back as Australia attempt to come through a week that was disrupted by a gastro bug in the squad.
Openside flanker Liam Gill, blindside flanker Scott Higginbotham, lock Sitaleki Timani and tighthead prop Ben Alexander were all affected by the bug.
Meanwhile, Brumbies hooker Stephen Moore has been replaced in the squad by Reds front-rower James Hanson. Moore has been ruled out after aggravating his troublesome hamstring injury.
