The Wallabies have toppled the Rugby World Cup defending champions, South Africa in a trench warfare thriller of a quarterfinal last night.

Robbie Deans men looked down and out as they soaked up a huge defence load and fell behind midway through the second half.

Somehow they found the character to fight back, landing a heart stopping penalty courtesy of James O’Connor and then holding on.

Is was the end of the road for the likes of Springboks captain, John Smit and lock Victor Matfield and some of the veterans of the game.

Captain, John Smit said it was hard to bow out in the quarter final, knowing how well they have played the game.
