The Wallabies believe their front-row critics will finally be silenced if they meet England in the Rugby World Cup quarter-finals.

Australian hooker Stephen Moore says the English scrum is a formidable unit and should provide a good gauge to see exactly where the Wallaby front row is at in comparison to other top nations.

"They have a lot of strength in their scrum with Andrew Sheridan, Phil Vickery to come back, and Matt Stevens scrummaged very well the other night," he told the Sydney Morning Herald.

"They are a very good scrum unit. While we respect them, they are certainly nothing that we fear."

The 24-year-old said the Wallaby pack could take a huge psychological edge into the semifinal against the All Blacks, should they progress that far into the tournament.

"That is what we are trying to build in the pool games, that momentum and combination going into the big games," Moore said.

"If we do happen to play England in a quarter-final - that is going to be a huge stepping stone.

"If we can get through that test - in the forwards particularly - we will be ready for anything."

Wallaby blindside Rocky Elsom singled out his side’s tight five as adding another string to their attacking bow.

"It definitely is a lot easier to play when the forwards are all working together, particularly in attack," Elsom said.

"Although the backs make most of the breaks, you need to get a lot of continuity out of your forwards. That was one of the big positives.

"We have a lot of skills. (Nathan) Sharpe is one who has a great set of hands he probably didn't know (he had) until 2006.

"Matt Dunning is a totally different player to what he was a couple of years ago. You see them get into the game a lot more.
