They are returning to a graveyard for Australian scrums and the Wallabies' forwards have been told to prepare for war against an England pack ready to be the Twickenham bullies.
But the Wallabies have been dealt a massive double blow in the build-up to the biggest clash of the World Cup so far, with Wycliff Palu (hamstring) and Will Skelton (shoulder) ruled out of the rest of the tournament.
Hooker James Hanson and lock Sam Carter have been called into the squad, with Palu and Skelton to fly home. 
The loss of Australia's two most powerful players is a huge hit as the Wallabies set out to exorcise their scrum demons at a venue where England have demolished them in the past.
Wallabies coach Michael Cheika has challenged England to try to bully Australia again, but insists his forward pack is ready for the challenge.
"I would say [they will use the scrum as weapon], that's where they have dominated us before - the scrums, mauls and stuff like that," Cheika said. "It's not the only thing. I think they have more in their game. But I think they will come hard for us there; you have to be ready for war in that part of the game."
Palu's 57-Test career is now almost certainly over as he gets ready for a move to Japanese rugby, falling short of the ARU's new 60-Test eligibility rule.
Hanson was controversially left out of the initial 31-man squad as Cheika opted for just two hookers - Stephen Moore and Tatafu Polota-Nau.
But Cheika has chosen to take no further risks as the Wallabies face do-or-die games for the rest of the World Cup.
Hanson has been playing in Australia's National Rugby Championship, while Carter has been in France with Top 14 club Bordeaux-Begles.
Palu was likely to miss selection against England because of the impressive combination of David Pocock at No.8 and Michael Hooper at openside.
But England will breathe a sigh of relief at Skelton's absence and the World Cup's second heaviest player leaves a huge gap in the Wallabies' line-up.
The Wallabies are banking on a new "all eight pushing straight" scrum philosophy to restore pride, and hope referee Romain Poite will pounce on England's wheeling tactics.
Poite was the man who continually ripped apart the Wallabies' scrum as it fell to pieces in the third Test against the British and Irish Lions two years ago.
But after rebuilding the set piece under Mario Ledesma's guidance, the Wallabies hope Poite is an ally in combating prop Joe Marler's tactics.
Marler has become an expert in illegally wheeling scrums without being penalised.
When asked if he hoped Poite would pounce on England's tactics, Cheika said: "The referees prepare very well for the game.
"All we can do is stay as square as we possibly can and make the opposition make their play from there, and see what happens. That's very much our strategy. I don't think it's any secret ... and also, put in massive amounts of weight.
"That's the way our scrum is set up and I'm sure they will have a tactic ... they very much bullied us in the scrum before and I think they will try to do it again."
Cheika said players put their hands up for selection in the 65-3 rout of Uruguay, with rookie flanker Sean McMahon in contention for a bench spot after a superb performance that was "pretty hard to ignore".
