Quade Cooper's Wallaby teammates have jumped to his defence, following controversial comments by ex-All Blacks coach Graham Henry in his recently released biography.

Henry labelled Cooper the Wallabies' "glaring weakness" at last year's Rugby World Cup in the new book, The Final Word.

The ex-coach also said that Cooper had often weakened Australia's back three in both a positional sense and for kicks in the air.

Cooper's teammates couldn't have disagreed more and showed their support for the 24-year-old.

Winger Drew Mitchell said the flyhalf had proven himself to his teammates and that is all they were focusing on.

"(Your teammates) are the ones you want to convince, and when times get tough you want to make sure the bloke you're playing next to knows you can do the job," he said.

Adam Ashley-Cooper had similar praise for the Auckland-born Cooper.

"Playing with him is always exciting. There's a lot of unpredictability around his game," he told journalists in Sydney, as his side prepares for the upcoming Rugby Championship tournament.

Meanwhile, Wallabies coach Robbie Deans was unimpressed with Henry's attack, even though he has not yet read the book.

"Quade's in the squad, he's returning to the game and he's working hard at that. He's a bloke that's played fairly in the past and he will in the future."

New Zealand-born Cooper had a difficult run in 2011 where he was the target of a great deal of Kiwi hostility at the Rugby World Cup.

He has not run out for the Wallabies since the tournament, having sustained a serious knee injury in the Bronze Final clash against Wales.
