Outspoken Australian fly half Quade Cooper has been charged with bringing the game into disrepute for his critical comments of the Wallabies and coach Robbie Deans.

The disgruntled star made headlines last month when he lashed out at the Wallabies set-up, saying the environment within the Australian team was "destroying" him.

The Queensland Reds playmaker, currently sidelined with a knee injury, reiterated his grievances on Fox Sports' The Rugby Club less than a week after first making his feelings known via social media.

Cooper is due to appear at a code-of-conduct hearing on Wednesday in Sydney.

An Australian Rugby Union spokesman said Saturday the ARU would not be making any official comment at this stage.

In interviews Cooper, 24, had expressed frustration about the defensive style of play favoured by Deans and said that he did not want to be involved with the Wallabies under the current regime.
