The Female Venereal Disease Isolation Hospital was established at the Brisbane General Hospital in 1911 where women were compulsorily detained under the Queensland Health Act of 1911. It was moved to a building adjacent to HM Prison Brisbane – Boggo Road in 1920.
Up to 1943 it was used for the confinement of “common prostitutes”, “promiscuous amateurs” and “delinquent girls”. From 1943 it was also used for “any woman found to have infected personnel of the fighting forces”. It reached its peak in November 1943 with 105 “inmates”. The increase in 1943 required expanding the facilities.
The discovery of penicillin resulted in the Queensland Government treating “venereal disease” as a medical issue rather than using punitive detention. The Isolation Hospital closed in 1948 and in 1950 became part of the “new” general female prison.
