Forget the scrum, forget the rain and, as Wallabies coach Robbie Deans puts it, strap yourself in for another wild ride with the brilliant Australian backline.

The Australians have given every indication there will be no returning to their shells in Saturday's (0130 Sunday AEDT) Test against England at Twickenham.

With most of the talk in the lead-up to the Cook Cup clash centring on what could be a mismatch in the scrums, the confident Wallabies look certain to play to their strengths and unleash the likes of Quade Cooper, Kurtley Beale and James O'Connor.

That will, of course, depend on securing enough possession but a smash-up in the scrum didn't curb Australia's willingness to go wide in last weekend's win over Wales.

"When the whistle blows we back them and trust them," Deans said of his rising stars.

"God knows we'd love to be out there playing but we're not and that's what the preparation through the week is for.

"Then we strap ourselves in and enjoy the ride."

Backing his coach, another of the attack-minded young Wallabies, Will Genia, said the team dubbed "the entertainers" by the British media weren't about to stop having fun.

"As a group we are learning when to have a go and when we do have a go, we are very effective," he said.

"It is good that it is starting to come together for us.

"It is exciting because when you go on the field you know you are going to have fun, you are going to throw it around and really have a go."

Rain is never far away in London, but Deans has predicted a firmer surface than the one the young Wallabies raced all over at the Millennium Stadium last weekend.

The conditions are likely to play a part, but Australia seem determined to test their flamboyant ball-play in whatever weather the UK serves up.

Regardless of what Australia's backs can conjure, plenty of eyes will still be on the shaky scrum that was penalised seven times in Cardiff.

Another demolition job would not only put the squeeze on the backs, but raise serious questions about how solid the framework of the Wallabies' World Cup Challenge will be.

Helping matters, hooker Stephen Moore returns from a back strain, while Huia Edmonds' powerful performances in Cardiff and Leicester have earned him a bench spot ahead of the lighter Saia Fainga'a.

Deans said there had been no panic after Wales, even as the Australian front row prepared to muscle up on scrummaging nemesis Andrew Sheridan and the fast emerging Dan Cole, who outplayed All Blacks champion Tony Woodcock last weekend.

"It's been a typical week," Deans said.

"We place an appropriate emphasis (on the scrum) every week.

"It's not a matter of chasing the bus, as soon as someone drops a ball you have a thousand catch-pass."

The Wallabies are shooting for a third straight Test victory against the world No.5 side as they eye a first unbeaten spring tour since 1998.
