The bill to criminalise gay conversion practices, which will be introduced to the upper house on Thursday, includes penalties of up to 10 years in jail and maximum fines of $10,000 for anyone caught trying to suppress or change someone's sexuality.

"There is absolutely no place for conversion practices in Victoria," Ms Britnell told The Standard.

"No one should be told they are broken and need to be fixed for being who they are and I of course support laws that stop that from happening.

"The Liberal Nationals have listened to a range of people, like the Australian Medical Association, who do have genuine concerns about parts of this legislation and as such amendments will be moved to address those concerns."

But Upper House Western Victoria MP Bev McArthur told The Standard she would not be commenting and would speak on the bill in parliament.

Brophy Family and Youth Services SAFE in the South West Coordinator Lyn Eales said it was imperative the bill passed with many faith-based communities supporting it and looking forward to a safer, inclusive environment for their communities.

"It will protect many people from enduring practices which seek to suppress or change peoples sexuality or gender identity," she said. "It has been three years since a major report by La Trobe University and the Human Rights Law Centre categorically confirmed the profound and lasting psychological harm caused by conversion practices in faith communities across Australia." The bill passed the lower house on December 10 last year.
