This page introduces the members of the Variations in Sex Characteristics Restricted Medical Treatment Assessment Board.

How members are selected

Members of the Variations in Sex Characteristics Restricted Medical Treatment Assessment Board are appointed and endorsed by the ACT Minister for Health.

The board members bring a range of skills to the board’s decision-making processes.  Members have experience in medicine, human rights, ethics, psychosocial care or lived experience of variations in sex characteristics.

The board’s oversight will give people with variations in sex characteristics and their families more confidence that they are agreeing to the best treatments for them. It offers a safeguard around care in a field that has a difficult history, including unnecessary surgeries.
