It is a horses for courses approach.

Those are the words of Wallabies coach, Robbie Deans in naming his run-on side to take on the All Blacks in the epic Rugby World Cup semifinal on Sunday night.

Deans is sticking to the same 15 that took the field in the quarterfinal win against the Springboks but on the bench there is no place for veteran, Nathan Sharpe who has played 99 Tests for the Wallabies.

There will be no chance for Sharpe to play his 100th test as he has been replaced with Rob Simmons.

It is a cruel blow for the Western Force second rower but Deans said they know what to expect from the All Blacks.
