Victorian Premier Daniel Andrews says the practice of gay conversion therapy is “bigoted quackery that masquerades as healthcare” and it will will be banned in the state.

The state government says the ban would be an Australian first and comes after an investigation by the Health Complaints Commission found the practice resulted in long-term psychological harm and distress.

Equality Minister Martin Foley Says It will be at least a year before legislation is introduced by parliament, allowing for consultation and to ensure the laws are exactly right.
