Australia is sick of being Scotland's prized ''scalp''.
Twice in four years the 10th-ranked Scots have claimed unlikely victories against the Wallabies. Captain Ben Mowen is determined it will not happen again.
''They claim a scalp every year, whether it's a Six Nations, in a June series, or on the spring tour,'' he said.
''They're relentless, they keep coming, and that says a lot about the spirit of the side. We've been [that] scalp twice, so they won't sneak up on us, that's for sure.''
Returning to the back line is Christian Lealiifano, the Wallabies' best goal kicker, whose turn at outside centre this week led him to joke he was the ''Samoan Stirling Mortlock''.
''I have more hair though,'' Lealiifano joked. ''I'm looking forward to it, the challenge of playing No.13 and being in that position and then goal-kicking.
''Ewen has backed me before in that role so hopefully I can reward him with some good kicks.''
The Brumbies playmaker, who was unluckily shut out of the starting side by his good friend Matt Toomua after missing two Tests with an ankle injury, has not played at outside centre since a stint in New Zealand's NPC three years ago.
A five-week ban for a dangerous tackle rubbed out Ewen McKenzie's first choice, Tevita Kuridrani, and natural replacement, Adam Ashley-Cooper, fell foul of team protocols.
But both players, known for their rock solid defence, have been putting Lealiifano through his paces at training this week.
''They've said that you've got a lot more time to see and make your reads in defence, and I'm seeing that in training,'' Lealiifano said. ''They're definitely testing me there, those boys, and I'm enjoying it.''
Mike Harris will have his first involvement in the match-day squad this year when he starts at No.12.
Fate has been kind to the Queensland back, who was given a warning after Tuesday's antics and now gets his first start in his favoured position.
''I've obviously been in the background on the tour so far so getting this opportunity is massive and something I don't take lightly,'' Harris said.
The 25-year-old made his debut at No.12 against Scotland last year.
He remembers the dreadful weather and the dreadful 9-6 result. Harris kicked all of Australia's points, but also sent up a poorly advised bomb that ended up in the shot at goal that won it for Scotland in the 82nd minute.
''They were some of the worst conditions I've ever played in … they're very physical, passionate and tough up front,'' he said. ''They've got a pretty good kicking game and in those conditions it really suited them.''
The Wallabies decided they would not appeal against the ban given to Kuridrani.
