Australian cricket chiefs have effectively told Al Jazeera to put up or shut up as the media company prepares a fresh documentary on alleged corruption in the sport.
Cricket Australia (CA) and the Australian Cricketers' Association (ACA) are criticising Al Jazeera for refusing to provide any evidence to support claims of match-fixing.
"Enough is enough when it comes to people making unsupported accusations that have the ability to unfairly tarnish players' reputations," ACA chief executive Alistair Nicholson said in a statement on Tuesday.
Al Jazeera is preparing its second documentary alleging match-fixing in cricket after an earlier program linked two un-named Australians to corruption claims.
CA chief executive James Sutherland said the governing body's integrity unit had reviewed the latest Al Jazeera claims made by "a known criminal source".
"From the limited information provided by Al Jazeera our team have not identified any issues of corruption relating to current or former Australian players," Sutherland said in a statement.
"We have handed all material over to the ICC Anti-Corruption Unit to enable them to fully investigate and we will continue to co-operate with the ICC.
"We urge Al Jazeera to provide all un-edited materials and any other evidence to the ICC Anti-Corruption Unit."
The ICC on Tuesday launched an appeal to find one remaining suspected match-fixer from Al Jazeera's initial documentary.
The alleged fixer, known as Aneel Munawar, remained unidentified but Al Jazeera had indicated he would be central to its second documentary, the ICC said.
"We have identified every other person in the original documentary and have spoken to a number of them in connection with match-fixing, including those who are not deemed to be participants under our Anti-Corruption Code," the ICC's Anti-Corruption Unit's general manager Alex Marshall said in a statement.
"However the true identity of Aneel Munawar remains a mystery.
"He plays a significant role in the program yet enquiries with law enforcement and immigration sources have not identified or located him."
Marshall said Al Jazeera's lack of co-operation had slowed ICC investigations.
"We are aware that there is a second documentary in the offing, this time based on historical recordings between a fixer, suspected to be Munawar and bookies in India," he said.
"Based on what we already know, we have engaged the services of an independent betting analysis company to examine the claims made about particular matches."
