Here's more details on his attempt to come out in 2000:
Ian Thorpe contemplated coming out as gay prior to the 2000 Sydney Olympics, but the swimming superstar decided against it because of the detrimental financial consequences suffered by a Canadian swimming star.
'I'm ashamed I didn't come out earlier because I didn't have the courage to do it,' Thorpe told British interviewer Michael Parkinson on Sunday night. 'I wanted to make my nation proud of me. I didn't know if Australia wanted its champion to be gay. I am telling the world I am,' he said.
In mid-2000 the late Terry Gathercole, the head of Swimming Australia, organised for Thorpe to talk to the high-profile, openly gay solicitor John Marsden.
Marsden told Fairfax Media at the time that he had organised a conference call with Canadian swimmer Mark Tewksbury, who had come out six years after he won the gold medal and broke the world record for the 100-metre backstroke at the 1992 Olympics.
Tewksbury said yesterday that he recalled speaking to Marsden but that Thorpe's identity was not disclosed. 'I always questioned his sexuality but his name was never revealed to me,' Tewksbury said.
Speaking from Canada, Tewksbury said that he had come out in 1998 because mere rumours that he was gay caused him to lose a 'six-figure speaking contract".
'I knew when I did it, there was a chance I could lose everything … that was the reality,'he said of the negative attitude of sponsors towards gay athletes at the time.
Tewksbury said he shared how 'tough' his decision was, but added it was also liberating. 'It was all worth it,' Tewksbury said. 'It's much more important than anything else.'
The day after the conversation with Tewksbury, Marsden told the Herald that the Canadian swimmer did not try to dissuade Thorpe from coming out but made sure he was aware of the financial consequences.
Marsden said Thorpe weighed up the advice and decided to postpone the announcement until later in his swimming career.
Thorpe's management has not responded to a request for comment.
