Australian swimming great Dawn Fraser said on Wednesday that drug cheats should be removed from sport.
Fraser was speaking about the use of drugs in sport after Australia's men's 4x100m freestyle relay squad admitted using a banned sedative in a bonding session before last year's London Olympics.
The Australian swimming team admitted using the prescription drug Stilnox in Sydney last week. James Roberts appeared with the team but said he had not taken the drug.
Stilnox, a brand of the medication zolpidem, is not banned by the World Anti-Doping Agency but was prohibited by the Australian Olympic Committee (AOC) because of its hallucinatory effects and after former Olympic champion Grant Hackett said he had become addicted to it.
Fraser told Sky News Australia after she was voted the country's all-time greatest female sportswoman at a ceremony in Canberra the swimmers had let the country down.
"In my eyes there's a huge hole in Australian swimming," said the 75-year-old, who won four Olympic golds between 1956-1964 and as many silver medals.
"Not only here in Australia but throughout the world and for us to be ridiculed right throughout the world with the announcement the other day of the minister saying, if you cheat we'll get you. Good on her I say, because we need to get the cheats out of sport. We don't need them, go and do it on your own ability I say and train hard and do it. Get rid of all drugs in sport. If you want to be good train hard for it."
The relay squad now face Swimming Australia's integrity panel.
