Returning breakaway David Pocock says the breakdown will be the defining battle zone between Australia and Wales at Millennium Stadium on Saturday.
Pocock makes his long-awaited return to the starting side after passing numerous fitness tests and training sessions before the Wallabies' spring tour finale in Cardiff.
Breakaway Michael Hooper moves to the bench with hooker Stephen Moore after coach Robbie Deans named Tatafu Polota-Nau to start in the front row. They are the only changes to the side which narrowly beat Italy in Florence last week.
Pocock has spent the past four weeks working with other squad members preparing dossiers on opposition teams while he recovered from the calf strain that delayed his return to playing before the test against France last month.
''The guys who haven't been playing have been previewing the next team and working on some stuff for a week ahead and then presenting that to the group,'' he said. ''There's seven or so guys who aren't taking the field but they're doing a lot of extra stuff away from the field.''
Pocock said Wales' last match, a 33-10 loss to the All Blacks, was a pointer to the importance of dominating the breakdown against the Warren Gatland-coached side.
''It was pretty ferocious and it's going to be the same on Saturday night,'' he said. ''It's really a team effort and it will obviously be a focus for us, so that's going to be somewhere we're going to have to do well and secure ball and hopefully put them under pressure.''
The Wallabies have run hot and cold on that aspect of their game over the past three tests but Pocock said it would take ''urgency'' and accuracy to win the contest against the Welsh. ''When you're over-committing you're short in other areas, so I think it's guys just doing their job,'' he said. ''At times we've been really good at that but there's definitely room for improvement.''
The Wallabies will start Kane Douglas in the second row with captain Nathan Sharpe, who will play his last game of rugby. Douglas has recovered from a knee injury to fill in for Sitaleki Timani after the giant forward was suspended for a week for striking Italy's Andrea Lo Cicero in Florence last week.
Another second-rower, Rob Simmons, had his eight-week suspension reduced to five, two weeks of which he has already served.
