A new Liberal politician hit out at sex work regulations and opening female-only spaces to trans women as she took aim at the “extremes” of equality and unity.

Western Metropolitan member Moira Deeming used her first speech to parliament to call for an inquiry into transition practices.

Ms Deeming blasted measures to include trans women in female-only change rooms and sports, claiming “what most women would consider to be sexual harassment and indecent exposure is now legal in Victoria”.

She also sounded off over sex work regulations and called on the government to reinstate sex-based rights in the law.

“Surely there must be ways to ensure the safety and dignity of trans people which do not trample on the rights of women and girls,” Ms Deeming told the upper house on Tuesday.

The former teacher said she left the profession partly because she was concerned lessons in tolerance were shifted to lessons in inclusion, primary school students were subjected to “erotic sexual content” and concerns about single-sex sport teams.

“Perfectly reasonable moral and religious differences were being reframed as discriminatory and intolerant, and a new vocabulary was introduced categorising people as allies or enemies,” she claimed.

Ms Deeming replaced outspoken politician Bernie Finn, who was expelled from the party after calling for abortion services to be banned and did not support the procedure even for rape survivors.

“I believe in freedom from compelled speech,” Ms Deeming said. 

“The freedom to travel outside my own suburb, the freedom to meet and embrace my family members and the freedom to accept or refuse medical treatment.

“These freedoms are under threat today, and as these last few years have proven.”
