Wallaby skipper George Gregan says Australia is prepared for an English backline blitz in their indoor Test in Melbourne on Saturday night, rating their game as the most expansive in world rugby.

Gregan said the widely-held notion that England played boring 10-man rugby was outdated, and he expected the visitors to fully utilise their attacking arsenal led by centre Will Greenwood and winger Jason Robinson.

Statistics back his theory, with England scoring 43 tries in its last 12 games, compared to Australia's 35.

"England play probably the most expansive game in world rugby when the conditions are right," Gregan said.

"You've got to play the conditions in front of you to win and they did that last week (against New Zealand).

"For them to be labelled 10-man rugby, maybe the people haven't been watching much of their footy over the last 12-18 months because they play with a lot of width.

"Their backs are very athletic, (Jason) Robinson's pretty sharp on his feet, Ben Cohen's very good, their new fullback's (Josh Lewsey) very good on his feet, we obviously know about Will Greenwood, he has very good ability in space, all those players can play."

Completing their final training session on Friday at Telstra Dome, Gregan said the Wallabies had no excuses for another lacklustre performance such as the one they delivered against Wales last Saturday in Sydney.

Australia heads into the match with a makeshift five-eighth in Nathan Grey, court drama with the players' association seeking an injunction against the Australian Rugby Union over World Cup player agreements, and its best forward Nathan Sharpe breaking down at training with a knee injury.

There have been suggestions that the axing of incumbent five-eighth Elton Flatley for disciplinary reasons and the selection of inside centre Grey, who has played only half a Test previously at No.10, gave the Wallabies an excuse if they failed to perform.
