Adriaan Strauss believes the visiting Wallabies will put on a vastly improved performance in their clash with the Boks at Newlands on Saturday.
The in-form hooker, who was asked questions at the opening of the Springbok Experience rugby museum in Cape Town, knew the home game would not be an easy task this weekend.
"We are clear in our minds that we are up against a very different Australian team than the one we beat in Brisbane," said Strauss.
"We know that this will be a very different game and a different challenge.
"The Aussies will be really motivated for this game, and they will be expecting much more from their players, especially the forwards. We are expecting a lot of emotion to be put into their scrumming, and they have had time to work on a few things."
South Africa are likely to need to win with a bonus point - depending on the result between the All Blacks and Pumas later on Saturday - to keep their chances of winning the Rugby Championship alive. But, echoeing the thoughts of coach Heyneke Meyer, Strauss stressed that they would first have to focus on getting a postive result before thinking of how many tries they score.
"We want to stick to the structures and the way we want to play. The game may open up later, and then we can perhaps worry about the bonus point, but we know we have to do the basics well," he said.
"In our game against them in Brisbane that is what we did and it worked. Our main focus this week is to win, and then if it is on for us to do so later on, then we will chase the bonus point."
