Re Australia - I don't know how 'respectable' the Courier Mail is, or how widely read, but I stumbled across this (published yesterday):

Minority of children with gender issues diagnosed with gender dysphoria, psychiatrist says

MANY children and adolescents are identifying as transgender because they are confused about sexuality or think it will make them “different”.
Psychiatrist Dr Stephen Stathis, who runs a gender clinic, said he had seen girls who had been sexually abused and wanted to identify as transgender.
“The girls say, ‘If only I had been a male I wouldn’t have been abused’,’’ Dr Stathis said.
He said the new statewide gender service at Brisbane’s Lady Cilento Children’s Hospital expected to see about 180 children with gender issues this year, but only a minority would be diagnosed with gender dysphoria.
Dr Stathis said by the time they reached puberty, most of those identify as their birth gender.
Gender dysphoria is a strong, persistent feeling of identification with the opposite gender and discomfort with one’s own assigned gender.
He said he had seen a lot of adolescents “trying out being transgender” to stand out.
“One said to me, ‘Dr Steve ... I want to be transgender, it’s the new black’,” he said.
