Interesting detransition history from Australia. A man named Alan Finch started up a detrans support group in 2009. Finch and a few others sued the clinic which resulted in an external review and closure of the clinic.
(Queensland government just earlier this week reinstated a ban on pubertal suppression for gender-related care, after the ban was overturned by the Supreme Court. Litigation for access to puberty blockers for trans children is presumed to persist in Queensland and elsewhere.)
