Australia's hopes of climbing back into Tri Nations contention have been dealt a crushing blow with second-rower Nathan Sharpe and classy centre Berrick Barnes ruled out of Saturday night's Test against South Africa in Perth.
Sharpe has failed to overcome a shoulder injury sustained in the loss to New Zealand last Saturday, while Barnes is still suffering concussion after taking a heavy knock in the one-point loss.
Bottom of the Tri Nations table after three losses, the Wallabies' odds of upsetting the Springboks have lengthened considerably following the loss of two key players.
Sharpe is regarded as one of the world's best lineout exponents, while Barnes' kicking game and composure in the midfield will be sorely missed.
Wallabies coach Robbie Deans is yet to make an announcement on replacements.
There was some good news from the Australia camp, with rugged flanker Rocky Elsom and young full-back James O'Connor both showing signs of improvements after picking up injuries against the All Blacks.
