The Wallabies say Beale was in high spirits on Saturday morning after being whacked at the bottom of a ruck early in the first half against Georgia. He left he field and did not return.

An eight-day turnaround will work in Beale's favour as he tries to recover for Australia's first knockout match of the tournament against England, provided Wales do not lose to Uruguay on Sunday.

Beale will undergo normal return-to-play protocols but as per Rugby World Cup rules, an independent doctor will come into Wallabies camp later in the week, according to a Wallabies spokesperson, and assess the 30-year-old alongside an Australian team doctor on either Wednesday or Thursday.

If they both determine he is fit to play, Beale will be named in Australia's match-day 23 on Thursday but if he is not given the green light, Dane Haylett-Petty is likely to be his replacement at No.15.

"He was more disappointed he wasn't out there with us but he was still in high spirits when I saw him this morning," said Wallabies vice-captain Samu Kerevi on Saturday. "He has still got that buzz about him and beautiful smile that we like to see. Obviously he will go through this protocols to return to play. I'm not sure personally where he is at with that. I saw him at recovery and he is feeling good. He was really buzzing about this week."

The Wallabies have changed plans and moved base to Odawara; a small city south-west of Tokyo, where they trained in the lead-up to their Cup opener against Fiji. Depending on the weather, Australia are set to stay there until Wednesday.

England, currently in Miyazaki, will catch a bus to Oita, the venue of Saturday's quarter-final, on Monday.

The promoter's dream of Australia-versus-England in a quarter-final has come to fruition, with head coaches and former Randwick teammates Michael Cheika and Eddie Jones once again set to go toe to toe.

Australia have suffered six consecutive losses against England since the last World Cup. A 3-0 home series defeat is still fresh in the memory, as are losses at Twickenham in 2016, 2017 and 2018.

It would be a tremendous turnaround if the Wallabies could conjure a win and progress to a possible semi-final against New Zealand.

"Anyone can talk about stats at the World Cup but we are just focused on our process for this week," Kerevi said. "[We want to] take our learnings from the Georgia game and go hard this week. I can't talk too much about the past. That's why it is in the past.

"If it is England, we are excited for the challenge ahead. They have some awesome players and some awesome firepower and we're excited to get stuck into the week."

Kerevi believes Australia's scrappy win over Georgia in the wet was a "perfect" tune-up to face an England side gifted a week off because of the cancellation of their match against France.

"It was really a forwards-dominated game with a lot of set piece," Kerevi said. "I think there are still areas we can improve and there are a lot of learnings from that game but I thought it was a really good game for us to head into the quarters.

"We've had the mentality of knockout footy from the get-go, especially after our loss to Wales which was hard for us to take. Our mentality has always been to build throughout the pool stages to where we are now."
