The party will push for parents to have the right to choose whether the information is included on certificates which means it would support the Greens’ amendment to a government bill to have gender markers completely removed.

Transgender lobby group, Transforming Tasmania, has been talking to the state’s parliamentarians to remove a legal requirement for reconstructive surgery to take place in order to change sex on birth certificates and for gender markers to be erased if parents chose to do so.

Greens leader Cassy O’Connor said Labor’s position was “a breach of faith with the transgender community”.

“I suspect they came under community pressure,” she said.

But Justice spokeswoman Ella Haddad said the party had worked hand-in-hand with the state’s transgender community, parents of transgender people and lawyers to reach its position which had been roundly accepted.

“I see this as the best way to achieve the intent of the change which is to enhance the rights of transgender people,” she said.

Ms Haddad said the amendments, if adopted, would mean a parent could choose to have gender on a birth certificate or leave it blank.

She said if a person later in life wanted to change that information, they could do so under “a simple administrative process” without the need for invasive reassignment surgery.

Attorney-General Elise Archer said Labor should agree to have the full range of reforms referred to the Tasmania Law Reform Institute for consideration and consultation. 

“Significant reforms of the type proposed by Labor and the Greens only weeks ago should not be rushed through the Parliament in an unrelated bill.”

Transforming Tasmania spokesperson Roen Meijers said there was no need for an inquiry into proposed gender law reforms, adding the government should stop trying to delay a free vote on the issue.
