Australia coach bulks up to combat Springbok power

Australia coach Robbie Deans has beefed up his pack in an effort to match the physicality of South Africa's set-piece in Saturday's Tri-Nations Test in Bloemfontein after defeat in Pretoria last weekend.

In three changes, hooker Stephen Moore and No 8 Ben McCalman were promoted from the bench while lock Mark Chisholm earned a recall having not featured for the Wallabies since earning his 51st cap against Ireland in June.

Lock Dean Mumm, hooker Saia Faingaa and No 8 Richard Brown drop to the bench, while loose forward Scott Higginbotham falls out of the match 22 completely from the team which lost 44-31 to the Springboks in Pretoria last Saturday. "The changes are less about shortcomings and more about considering the order in which we will use our blokes," said Deans. "McCalman has done really well off the bench and he will bring a real physical presence. Mark Chisholm has a big frame and we want him to use it at the set-piece.

"We believe that we will be better for the added weight in the scrums," added Deans.

The 22-year-old McCalman will be making his run-on debut after two substitute appearances while the match will be a special occasion for Moore and wing Drew Mitchell with both men set to reach the 50-test mark on Saturday.

Mitchell said that despite reaching the milestone he was more focused on his team's performance.

"It's a tremendous honour to reach 50 caps but at the moment there is a bigger picture," said Mitchell.

"It is a very important time for the team. Being as close as we were on the weekend and not being able to come away with a win is pretty disappointing."
