Victorian Opposition Leader Matthew Guy is under pressure to give parents greater access to gay 'conversion' therapy for their children, with sections of the Liberal Party set to push the issue at this month’s state council meeting.

With seven months before the Victorian election, it also urges Mr Guy to advocate for laws ensuring “parents and young people are all given full information about the psychological harms of social, medical and surgical gender transitioning”.

It further states that any claims supporting prescribing puberty blockers, cross-sex hormones and gender re-assignment surgery as safe and reversible, are in fact "both false and harmful".
