S Africa v Australia - Teams

South Africa have made two enforced changes to their starting line-up for their final game of this year's Tri-Nations against Australia.

The Springboks have winger JP Pietersen out through injury and CJ van der Linde suspended, so Odwa Ndungane and Brian Mujati have been drafted into the XV.

Coach Peter de Villiers keeps faith with the remainder of the side that lost 27-15 to the Wallabies last weekend, as he continues to implement their new game plan.

"The Peter de Villiers game plan is all about adding decision-making to structure and we are stuck at the moment at decision-making," he said.

"But I back the players and I want them to keep going out and playing what's in front of them. The win will come because we have very good players."

There are three changes to the bench, with Jannie du Plessis replacing Mujati, utility forward Danie Rossouw coming in for Joe van Niekerk and utility back Ruan Pienaar replacing Francois Steyn.

Steyn - and winger Bryan Habana - were not considered for the match because of injuries, Habana is nursing a hamstring strain while Steyn is suffering from concussion.

"We need to win this game for South Africa, the coaching staff and all those involved with the Boks," said captain Victor Matfield, who passed a fitness test to play.

"We certainly don't want to get together at the end of the year (for the tour of Europe) still asking ourselves questions about our game.

"We need to build some confidence now and ensure we take the chances we create this weekend."

De Villiers' team has lost four out of five matches in the Tri-Nations but haven't lost to the Wallabies at Saturday's venue of Johannesburg in 45 years.

Tahu starts

Australia hand a first international start to cross-code convert Timana Tahu.

Tahu has been selected at inside centre in place of Berrick Barnes, who has a shoulder injury, in one of five changes to the XV that won in Durban.

Rocky Elsom takes his place in the back-row after successfully appealing against a one-match ban for dangerous play.

Adam Ashley-Cooper has recovered from a broken hand and replaces Drew Mitchell at full-back, Hugh McMeniman fills in for injured lock Dan Vickerman, while Phil Waugh and Tatafu Polota-Nau come in for George Smith and Stephen Moore respectively.
