Prime Minister Scott Morrison says he will never become involved in any debate about so-called gay "conversion therapy", which has been discredited by psychiatrists across the world.
The prime minister was on Monday asked for his views about the
"I respect people of all sexualities, I respect people of all religions, all faiths. I love all Australians," he told Melbourne radio 3AW.
People should make their own choices about their lives.
"I've never been involved in anything like that, I've never supported anything like that, it's just not an issue for me and I'm not planning to get engaged in the issue," Mr Morrison said.
A coalition of survivors, churches and community advocates are urging the Morrison government to address the issue ahead of the next election.
Some 43,000 signatories to a survivor-led petition sent to Mr Morrison and Opposition Leader Bill Shorten called for greater powers for health and consumer watchdogs, tougher regulations on counsellors, and a public health and awareness campaign.
The PM's comments have angered some Twitter users, who have decried conversion therapy as "damaging".
Labor has indicated it will crack down on the issue if the party wins government, and the Greens have long argued for reform.
"Conversion therapies and sexual orientation change efforts are harmful and can have fatal consequences. They must must be stamped out," Greens senator Janet Rice said on Monday.
"The basic premise of conversion therapy and sexual orientation change efforts is that LGBTIQ people can and must be changed, rather than being perfect and accepted for who they are."
Earlier this year, Victorian Liberals president Michael Kroger stepped in to stop a motion on gay "conversion" being debated at the party's state council.
A branch of the Young Liberals called for the law to be changed to ensure doctors "can offer counselling out of same-sex attraction or gender transitioning".
It also called on the state government to give parents and minors "full information about the psychological harms of social, medical and surgical gender transitioning".
The proposal prompted outrage from LGBTI advocates both inside and outside the party.
Mr Morrison said he had never thought about it.
"People should abide by the law. If people aren't breaking the law, that's a matter for them," he told 3AW.
