In 2001 the NSW Ministerial Taskforce on Brothels Final Report outlined NSW sex workers great sexual health record and how they maintain it, here is an extract from pg 14.
“The prevalence of HIV infection and sexually transmitted diseases among Australian sex workers remains one of the lowest in the world. This low prevalence rate is unique in the Asia Pacific region, which has been identified as having the fastest growing HIV/AIDS epidemic globally, and which has identified sex workers as a highly vulnerable group.
The low STI and HIV/AIDS prevalence in NSW sex workers is largely due to the voluntary cooperation of sex workers with outreach and advocacy services. These services are undertaken by specialist sex worker projects in addition to the statewide network of sexual health services. These measures protect public health by minimising the transmission of disease and infection.”
