Tournament hosts England must beat the Wallabies at Twickenham on Saturday to keep their campaign alive and avoid the ignominy of departing a World Cup at the pool stage for the first time.
Despite losing to Wales last weekend, 2003 champions England remain 4-5 favourites to win the match with the twice champion Australians 5-4 and the draw 18-1.
Holders New Zealand, who play their third pool match against Georgia later on Friday, remain even money favourites to retain the Webb Ellis Cup.
