Paediatrician Dr Michelle Telfer has one of the most controversial jobs in medicine in Australia. As head of the Royal Children's Hospital Melbourne's (RCH) Gender Clinic, she's responsible for overseeing the treatment of hundreds of trans children and teenagers who come through the doors. The former Olympic gymnast-turned-doctor and mother-of-two credits her early athletic success with building the stamina needed to tackle her critics who question the need for medical treatment for trans young people. Australian Story goes behind the scenes at the RCH to meet three of Dr Telfer's patients, Isabelle, Elliot and Oliver.
