Drug use is widespread in Australian sport, with growing links to organised crime, according to a damning official probe released on Thursday that points to "clear parallels" with the Lance Armstrong case.
The Australian Crime Commission inquiry identified common use of prohibited substances including peptides -- a type of stimulant -- hormones and illicit drugs, with no professional sporting codes immune to the scourge of doping.
The findings from the year-long investigation indicated that sports scientists, coaches, support staff as well as doctors and pharmacists were involved in the provision of drugs.
In some cases, players were being administered with substances that have not yet been approved for human use.
"The findings are shocking and will disgust Australian sports fans," home affairs minister Jason Clare said.
"Multiple athletes from a number of clubs in major Australian sporting codes are suspected of currently using or having previously used peptides, potentially constituting anti-doping rule violations.
"Officials from clubs have also been identified as administering, via injections and intravenous drips, a variety of substances.
"It's cheating but its worse than that, it's cheating with the help of criminals," he added.
The report said there were "clear parallels between what has been discovered in Australia and the USADA (US Anti-Doping Agency) investigation into Lance Armstrong", referring to the disgraced Tour de France cyclist.
This "underlines the transnational threat posed by doping to professional sport, both from a 'fair play' perspective and as a broader integrity issue".
"It is also clear from the findings of this project, the USADA investigation, and previous high-profile doping cases in Europe and the United States that it is not only athletes who are involved in doping, but athletic support staff, organised criminal groups and complicit doctors."
The report said criminal networks were increasingly involved in the distribution of illegal substances, and the links may have led to match-fixing and fraudulent manipulation of betting markets.
Crime Commission boss John Lawler said the threat of match-fixing was "extraordinarily serious" with organised crime involved.
"Organised crime has many facets. It will go to where there is lucrative profits to be made, low risk, regulatory weakness, and they will exploit those vulnerabilities," he said.
Sports minister Kate Lundy said all sports had committed to work with the government, the Australian Sports Anti-Doping Authority (ASADA) and law enforcement agencies to restore confidence in sport.
"This week the government introduced legislation to strengthen ASADA's powers to enable the full and unhindered investigation of these issues," she said.
"If persons of interest refuse to cooperate with ASADA investigations they will be liable for civil penalties."
She added that all major professional sports would establish integrity units to deal with doping, betting and ethical issues.
