Springbok coach Peter de Villiers is cautious about his team getting ahead of themselves as they prepare for Saturday's Tri-Nations clash against the Wallabies in Brisbane.

South Africa are sitting pretty at the top of the standings and a victory at the SunCorp Stadium will see them claim the title for third time since its inception.

However, De Villiers remained coy about his team's favourable position in this year's competition and he suggested that they won't be resting on their laurels anytime soon.

"We have not won the Tri-Nations title yet and there are still two tough games to play," he told the media in Brisbane.

"We are focussing on the immediate task at hand and that is to do well against Australia on Saturday."

The coach was also asked what it would mean if the Boks were successful in winning all six of their Tri-Nations games in 2009.

"We are trying to be the best that we can be. We do not chase records but strive to improve on each and every performance," he said.

"This team can still get much, much better and is playing winning rugby whilst still making errors. It excites me when I think of what these players could still do on the field."

The match will also mark the 50th Test appearance for centre Jaque Fourie, who is the fifth player after Schalk Burger, Bryan Habana, Jean de Villiers and Fourie du Preez to reach the milestone in 2009.

"It is a fantastic honour to represent your country and I am looking forward to getting my 50th cap," he said.

"There are a lot of guys in the squad now who have reached 50 and several others who are in the 80's which brings great experience and composure to the team. The spirit is great in the camp and the guys are eager to do well at the weekend," Fourie said.

The Springboks have made two changes to their match 22 to face Australia which have been enforced by injuries.

Sharks wing Odwa Ndungane will take the place of JP Pietersen in the starting line-up, whilst Bulls lock Danie Rossouw makes a return to the bench in the place of Western Province's Andries Bekker.

The match will see Ndungane, who last played for the Springboks in the final Test against the British & Irish Lions in July, earn his fifth Test cap.

De Villiers said that including Ndungane had not been a difficult choice: "Whilst we have a lot of versatile players in the squad, Odwa is a natural winger and therefore was the first choice. He has been running the moves with us for some time and is familiar with the defensive patterns so he should fit in pretty easily".

Ndungane said he was glad to get the opportunity to start: "I am looking forward to it. It is a great chance for me to get some game time and hopefully I can make a contribution to the success of the team".
