Queensland's sports minister has used a confidential briefing to express major concerns with the way the drugs in sport probe has been handled.
Steve Dickson was given a briefing on Thursday night by the Australian Crime Commission and Australian Sports Anti-Doping Authority on their investigation into professional sport.
He said the matter could have been handled much better and the lack of detailed allegations was frustrating efforts to engage children in sport.
Mr Dickson said all sporting clubs should be making their anger about being under a cloud of suspicion known.
"In Queensland, I'm trying to get kids involved in sport and this is very difficult under circumstances where every club in this country is being tainted as possible drug users," he told ABC radio.
Mr Dickson said the nation's "brand" had already begun to suffer, along with the reputations of individual sportsmen and women, and that would go on until more information was given.
