Olympic swimming champion Ian Thorpe says it will be tough to stomach a victory for the no campaign in the same-sex marriage postal survey but he is confident Australia will be voting yes.
"It would be really difficult to be in a country where we haven't voted for equality, where we haven't voted for fairness," he told reporters in Canberra on Thursday.
"Because you take that not only personally, but it isn't the kind of future that I want to see for Australia."

Equality campaign advocates are urging Australians to post their votes before 6pm Friday, to ensure they are received by tally rooms before the survey closes on November 7.
Thorpe said he would continue campaigning for same-sex marriage in the event of a win for the no vote to give equality for the LGBTI community.
"We will keep fighting for it, but I don't think we're going to get a no vote."
"I think it will be a resounding yes."
Earlier this week the Australian Bureau of Statistics said three out of four eligible Australians had voted, with an estimated 11.9 million (74.5 per cent) survey forms received.
