Sydney - Prostitution is regulated differently in Australia's six states, allowing researchers like Basil Donovan to compare how the industry operates under different rules and the implications for public health.

Donovan, from the University of New South Wales, found that sex workers in his state had the lowest incidence of sexually transmitted disease.

If the health of those who work in the industry was the only consideration, he argues, other jurisdictions should fall into line with the biggest state and decriminalize prostitution and deregulate the industry.

"The prevalence of gonorrhoea in sex workers in Sydney is as close as you can get to zero," Donovan, an internationally recognized expert in sexual health, said.
