Hundreds of Victorians have officially changed their sex on official documents with more to come under proposed law reform.

The Andrews Government has reintroduced a bill that would allow people to change their gender on official documents without undergoing medical procedures. New figures reveal just how many Victorians are already changing their gender per year.

Martin Foley said the bill was a step forward for all LGBTIQ Victorians.

More than 30 people a year are changing their gender in Victoria, according to new data.

Figures collated by Registry of Births, Deaths and Marriages Victoria reveal 250 people had their new gender recognised on their birth certificate over an eight-year period.

This includes 38 Victorians in 2017/18, and 33 in the 12 months before, who chose to be registered as male, female or another non-binary option after undergoing sex affirmation surgery.

The annual figures have remained relatively stable since June 2009.

However, the number could rise in the future, with a proposed state law allowing people to change their gender on official documents without undergoing medical procedures.

Transgender advocates have welcomed the move, saying it will remove red tape and help tackle prejudice around the issue.

Minister for Equality Martin Foley said the bill — reintroduced to state parliament in June — was a step forward for LGBTIQ Victorians.

“The Andrews Labor Government believes in everybody’s right to simply being who they are, and being supported in that,” Mr Foley said.

“Since being elected in 2014, we have invested more than $60 million in initiatives that make our community fairer and more equal.

“We’ll continue to ensure every LGBTIQ Victorian, including trans, gender diverse and intersex Victorians, feel safe and supported in our community.”

If passed, the legislation will bring Victoria into line with the Australian Capital Territory, Northern Territory, SA, Tasmania and WA.

The state opposition has not immediately ruled out supporting the bill but is flagging it intends to examine the legislation carefully.
