Tasmanian Liberal MPs will be allowed a conscience vote on a Greens bill to ban conversion practices, which are attempts to suppress or convert a person's gender or sexual identity.
Liberal minister Felix Ellis says he'll be "voting no", but the Greens say the reasons he's given for not supporting the bill are "misleading".
The bill is expected to be debated in parliament this year.
Mr Rockliff, who supports the "general principle" of banning conversion practices, before said if one of his MPs asked for a conscience vote, it would be granted.
Police Minister Felix Ellis posted on social media this morning that he would be voting "no".
"That care means honest, individual, evidence-based medical care from professionals who are free to use their best judgement and parents able to provide loving guidance."
Backbench Liberal MP Michael Ferguson also published a statement on Friday morning saying he would vote against the bill.
Attorney-General Guy Barnett has also before raised concerns about the bill.
Tasmanian Greens deputy leader Vica Bayley said Mr Ellis's statements were "misleading".
"Our proposal to end conversion practices isn't radical."
"The conversion practices this bill aims to stop are acts that intentionally try to change, suppress or eradicate the sexual identity or gender of a person."
The Tasmanian Law Reform Institute found in 2022 that "severe harm" had been caused by conversion practices.
In a statement to the ABC today, Mr Rockliff said he still agreed with the banning of conversion practices "as a general principle".
Attempts to ban conversion practices nationwide and in Tasmania have also been opposed by the Australian Christian Lobby.
