Former England forward and captain Martin Corry is confident of a backlash from the home nation against the Wallabies at Twickenham this Saturday.
Since their 28-25 defeat to Wales last weekend, criticism from several quarters has hit the English camp, with Will Carling one of the most notable voices.
England's players and coaching staff have responded with a steely resolve and in some cases anger, as they sit in third spot in their pool with two games left.
And Corry believes such a mindset should come as a warning to their next opponents, Australia, as he expects a relentless performance from England.
"They sound really angry and that's the reaction you want," he told BBC Radio 5 live.
"Listening to them talking they are pulling together and now I expect something big to happen as a result against Australia."
After facing the Wallabies, England take on Uruguay in Manchester on October 10.
