Australia must come clean on the report which cleared five cyclists or it risks tarnishing the reputation of every athlete travelling to the Olympics, the world's anti-doping chief says.

World Anti-Doping Agency boss Dick Pound said only full disclosure of any doping reports would clear Australia's name before Athens next month.

"Part of the problem is we don't really know exactly what has been done, and you'd think that everybody involved from the government on down would be making every effort possible to clean it up and show what has been done, rightly or wrongly," Pound told Channel Nine's 60 Minutes program.

Australia's team for the Athens Olympics is expected to be finalised this week provided authorities can resolve at least two drug scandals.

Hanging over the Australian Olympic Committee (AOC) as it prepares to name about 450 athletes for Athens are the cases of weightlifter Caroline Pileggi and cyclist Jobie Dajka.

Pileggi - dumped from the Athens squad after it was revealed she refused a drugs test while training in Fiji last month - will make her case for reinstatement before the Administrative Appeals Tribunal (AAT) in Melbourne on Thursday.

Dajka is one of the five cyclists investigated by retired WA judge Robert Anderson.

All five were given preliminary clearance last weekend, although the judge said he had reservations about aspects of Dajka's evidence and was waiting on a South Australian police investigation.

Judge Anderson's report followed claims from junior cycling champion Mark French.

French has been banned from cycling for two years by the Court of Arbitration for Sport (CAS), and for life from the Games by the AOC, after being found guilty of trafficking the prohibited product Testicomp and possessing the horse growth hormone EquiGen.
