After their shock 15-6 defeat to Ireland in Auckland on Saturday, the Wallabies should get the better of their less-fancied opponents and anything less than a huge winning margin will not satisfy their supporters.
Scrum-half Will Genia leads the Tri-Nations champions in the absence of regular captain James Horwill, who is being rested for the encounter.
Despite losing their last match, Australia are still among the favourites to win the tournament and they should run rampant in this encounter.
An area of concern for Wallabies coach Robbie Deans is his side's performance in the scrums, after they took a battering in the set-phase against Ireland.
Tighthead prop Ben Alexander, in particular, will have a point to prove after his poor showing against Ireland's Cian Healy.
If it's any consolation for the Wallabies it must also be remembered that Ireland also destroyed USA in the scrums when they beat them 22-10 in New Plymouth on September 11.
Quade Cooper also gets a chance to redeem himself after his below par performance in Auckland and along with Genia will once again pull the strings on attack for the Wallabies.
The defeat against Ireland has given opportunities to some of Australia's second-stringers to stake a claim in the starting line-up for the knockout stages and the likes of Drew Mitchell, James Slipper and Scott Higginbotham will probably fancy their chances of achieving that goal if they put in strong performances in this clash.
Another player to keep an eye on is number eight Wycliff Palu who although he made an appearance off the bench against Ireland will start his first match for the Wallabies since 2009.
He has had a bad run with injuries which has seen him having surgery to his knee and shoulder, a hamstring tear and an arthroscope on the same knee.
However, a fully fit Palu is one of the most fearsome sights in the game and Deans will be hoping the hard-running back-rower makes an impact in this match.
USA coach Eddie O'Sullivan is a shrewd tactician, who has coached Ireland at previous World Cups, and after making 14 changes to his run-on side after their win over Russia, one can't help but wonder if he is sacrificing this match with the hope of beating Italy in their final pool match.
Irishman O'Sullivan expects a response following Australia's loss to his
compatriots.
The USA boss said: "I think any team that comes off a defeat, the next time out they always want to make a statement.
"I have no doubt that will be the intent of Australia against us: to show that they are back on track."
Australian-born scrum-half Tim Usasz will captain the team for the first time, taking over from regular skipper and openside flanker Todd Clever.
