Sitaleki Timani, Dom Shipperley and Stephen Moore have been cleared to tour South Africa and Argentina.
The Wallabies will be without Quade Cooper for their remaining two Rugby Championship Tests, but the good news is that three of their charges have recovered from injuries, and have been included in the touring squad.
Coach Robbie Deans has also called up prop Paddy Ryan and wing Nick Cummins. Both men are yet to be capped at international level.
The Wallabies will play the Springboks in Pretoria on 29 September, and the Pumas in Rosario on 6 October.
Wallabies squad to tour South Africa and Argentina: Adam Ashley-Cooper, Kurtley Beale, Digby Ioane, Dominic Shipperley, Nick Cummins, Ben Tapuai, Anthony Fainga’a, Pat McCabe, Berrick Barnes, Mike Harris, Nick Phipps, Brett Sheehan, Scott Higginbotham, Radike Samo, Michael Hooper, Liam Gill, Dave Dennis, Rob Simmons, Nathan Sharpe, Kane Douglas, Sitaleki Timani, Ben Alexander, Paddy Ryan, James Slipper, Benn Robinson, Saia Fainga’a, Stephen Moore, Tatafu Polota Nau.
