Australia's Olympic athletes will be required to sign statutory declarations saying they have no history of doping.
The Australian Olympic Committee (AOC) said in a statement on Tuesday that athletes competing at next year's Winter Games in Sochi will be the first to sign the mandatory document in the wake of recent doping revelations.
It said anyone who does not make the declaration will be ineligible for membership of any Australian Olympic team or shadow team.
An Australian Crime Commission report released last week said it had found widespread use of banned drugs among professional and amateur athletes, with links to gambling and organised crime.
The Australian anti-doping officials met with six National Rugby league clubs on their investigation process on Tuesday after the clubs confirmed they were under scrutiny.
The AOC warned false declaration would incur harsh penalties for athletes and even officials. It would be a criminal offence and could incur a jail sentence of up to five years.
Declaration details would be shared with the Australian Sports Anti-Doping Agency (ASADA).
