Pauline Hanson says she would vote for same-sex marriage legislation in the Senate if that's what the people of Australia say they want in a plebiscite.

In an interview on Melbourne gay and lesbian radio Joy FM, she said she didn't personally favour gay marriage.

But if the people of Australia wanted it, she would back it, she said.

""I would support that because people have had their say. I'd give it my total support because I'm there as the people's representative. I believe we've got to start listening to the majority and not the minority," she said, according to a Fairfax media report.

Senator Hanson suggests the plebiscite be held in conjunction with the next federal election in around three years' time.

She also says fears that the proposed plebiscite would produce an outpouring of hate directed at gays and lesbians are overblown.

"I think you are actually blowing that out of proportion to make that an excuse why you shouldn't have a plebiscite," she said, adding she believed it would be a balanced debate.

Senator Hanson said everyone had the right to peace and harmony.

"But the gays and lesbians are now wanting to change my way of thinking, who I am," she said.

"You want to take something away from the majority of society that we've grown up with. Why do you want to take the word marriage?"
