Victorian Liberals president Michael Kroger has intervened to stop a motion on gay "conversion" therapy being debated at the party's state council.
The move follows criticism from federal MPs on Monday that described the motion as a "dark" throwback to the 19th century.
The proposal, from a Young Liberal branch linked to veteran federal MP Kevin Andrews, called for the law to be changed to ensure doctors "can offer counselling out of same-sex attraction or gender transitioning".
Seven months before the Victorian election, 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 Sunday Age revealed the motion on the weekend. It prompted outrage from LGBTI advocates within the party.
Mr Kroger on Monday confirmed he had contacted the Menzies-Warrandyte Young Liberal branch, which had proposed the motion, and told them it was "inappropriate".
The Age understands they agreed to withdraw the motion.
And Opposition leader Matthew Guy said there was “absolutely no chance” he would support or allow any form of gay conversion therapy.
“After everything I’ve said supporting same-sex marriage, calling for the party to engage the gay community and others... as if a government I lead would consider anything as ridiculous as that," he said.
Mr Kroger said he had contacted two branches about motions they had submitted.
The other motion was submitted by the Geelong senior branch and called for "sexual orientation" to be removed entirely from the federal Sex Discrimination Act, enabling discrimination against LGBTI people, and replaced with the terms "man" and "woman".
Trent Zimmerman, a gay federal Liberal MP, said the proposals were "out of touch" and damaging to the party's brand.
"These are the types of policies you would expect to find in the dark recesses of the 19th century or in the forums of the Australian Conservatives party – not in the modern Liberal Party," he said on Sunday.
"The real debate is whether so-called gay conversion therapy should be regarded as a form of child abuse."
Dale Park, co-convener of the Victorian Gay and Lesbian Rights Lobby, said it was "fantastic" that the motions had been removed from the agenda.
"Any suggestion that conversion therapy is accepted or even debated really shows a concerning viewpoint," Mr Park said.
"It's very positive that those in the Liberal Party that don't agree with this have stepped up."
The Victorian Liberal Party's state council will be held later in April.
