Every international team have their strengths but the Springboks are a particularly physical side - it's been the same since year dot.
The physical confrontation is what blows away most of the Springbok opposition and we are one of the few teams in the world who can handle the physical factor.
We saw in the weekend that the Wallabies can't handle it, but we can.
When a Springbok team are playing well, the only side in the world who can beat them are New Zealand and sometimes we can't beat them either, which is why I think they are our number one adversary.
The Australians have had their moments through being clever and playing a good brand of rugby but they lack the physical presence of the Springboks, who are big, strong men used to playing at a fast pace in good conditions.
