Uncapped wingers Nick Cummins and Dom Shipperley are in line to battle for a Wallabies debut after being named in a 31-man squad ahead of next Saturday's Rugby Championship clash against South Africa.
The training group will assemble in Perth on Sunday as they prepare to bounce back after being humbled 22-0 by New Zealand in Auckland last weekend.
Waratahs winger Drew Mitchell suffered a recurrence of an ankle tendon injury at Eden Park which ruled him out for the remainder of the season.
If Adam Ashley-Cooper retains his place at fullback in preference to Kurtley Beale, Cummins and Shipperley are set to fight it out for one winger's spot given Digby Ioane is a certainty for the other.
The closest Western Force utility back Cummins has previously come to a Wallabies jumper was in 2010 when the 24-year-old toured South Africa during the Tri Nations.
