England beat Australia in 2000 and 2001

England will be looking to complete the second leg of their southern hemisphere triple crown when they take on Australia at Twickenham on Saturday.

The Wallabies may be the world champions but England will start the match at Fortress Twickenham as favourites.

The hosts have not lost at Twickenham for 16 matches and go into the game on the back of a thrilling 31-28 victory over Tri-Nations champions New Zealand.

Australia, on the other hand, have been looking some way short of their best this year and lost to Ireland for the first time in 23 years last Saturday.

Despite beating the All Blacks, coach Clive Woodward was fairly disappointed with England's performance last Saturday and he is looking for an improvement against Australia.

Woodward felt England only performed for 30 minutes and has rung the changes in the pack as he looks to get England playing for the full 80 minutes.

Prop Trevor Woodman has been forced out with a neck injury, allowing Jason Leonard to win his 98th cap, while the other two changes are tactical.

Former captain Lawrence Dallaglio loses his place in the back row, with Neil Back coming into the team at open-side and Richard Hill moving to number eight.

And in the second row Back's Tigers' team-mate, Ben Kay, gets the nod over Danny Grewcock.

Australia coach Eddie Jones has given his pack a complete overhaul and also made a change in the backs.

Sole survivor

Argentina-born prop Patricio Noriega is the only front-five survivor from the Ireland game.

Bill Young comes in for Nick Stiles at loose-head and Jeremy Paul replaces Adam Freier at hooker.

In the second row Justin Harrison and Daniel Vickerman are recalled in place of David Giffin and Owen Finegan, while Elton Flatley has been brought in at inside-centre.

Sailor has yet to make a major impact in union

Flatley will share the play-making duties with fly-half Stephen Larkham and the Wallabies are likely to make full use of the decoy runners that New Zealand employed last Saturday.

Woodward subsequently questioned the legality of some of the All Blacks' moves, claiming that they were using blockers to free their runners, but Jones cannot see a problem.

He said there was only one International Rugby Board interpretation of what blocking was, and he would ask the referee, New Zealander Paul Honiss, to apply it.

Decoy runners or not, both sides will be looking for a greater cutting edge out wide.

And league converts Jason Robinson and Wendell Sailor are both devastating runners when given the chance to cut loose.

The Australians have lost on their two previous visits to Twickenham.

And, although the world champions can never be written off, England should have the pace and power to make it a hat-trick of victories.
