The Wallabies have long since realised there's no taller order in international rugby than combating South Africa's twin peaks Victor Matfield and Bakkies Botha.

The task is bound to prove even more troublesome on Saturday when the lock legends extend their world-record partnership against Australia to 50 Test matches together in South Africa's second row.

The milestone is sure to inspire Matfield and Botha to reach even greater heights at Newlands.

It is a frightening prospect but one which the Wallabies say they are ready for.

Ultimately, Nathan Sharpe and James Horwill will share the responsibility of containing the pair of man mountains come lineout time.

But the pressure is also well and truly on Wallabies hooker Stephen Moore to land his throws and he is confident of hitting the target.

"We must ensure that we are accurate. I am confident that we can get a result," Moore said.

"Victor has been dominant in the lineouts for a number of years. This year has been no different. He has showed what he can do and we are fully aware of the threat they will pose in the lineout.

"But we are pretty happy with how our lineout has gone so far this year. The guys will work it out."

Springboks captain John Smit is expecting the Wallabies to present their own lineout challenges and said his side's would need to function better than in last Saturday's 31-19 win over the All Blacks in Durban.

"We were not very happy that we lost two lineouts this week on our own ball, which is not something that we like to make a habit of," Smit said.

"There's a lot of work that gets put into that and we've got to start all over again.

"We've had an opportunity where we had the All Blacks two weeks in a row, which makes it that little bit easier from a preparation point of view.

"We haven't really had a crack at the Wallabies for quite some time.

"I'm sure they're going to bring a few surprise packages in the lineouts so it will be a little bit tougher to decide what they're going to bring."

The Wallabies at least think they know what's coming their way, with forwards coach Jim Williams saying he'd be very surprised if the Boks didn't try to put their notorious rolling maul to use from secured lineout ball.

Williams said the Wallabies had worked hard on countering South Africa's well-used tactic.

"It's always something that's evolving and changing so the ability of your forwards to evolve with that is important and it's always a tight tussle competing against it and actually using it as a weapon," he said.

"So it's going to be fascinating to see how things unfold on the weekend."
