Sex work

Many people have either worked as a sex worker or engaged sex workers’ services. Estimates suggest many thousands of people engage in sex work in any given year. The Australian Institute of Criminology[1] cites estimates of 1,500 to 10,000 working in NSW at any one time, though many of these estimates count only female sex workers. The Western Australian Government’s Prostitution Law Reform Working Group cites an estimate of some 1200 to 1700 sex workers operating in WA (Prostitution Law Reform Working Group[2] 2007).

The number of clients of sex workers during any given year is not known. Three Australian studies have found that approximately one in every six or seven men admit to having paid for sex at least once. Richters et al.[3] found 2% of men surveyed reported paying for sex in the last year . Woodward et al[4] go further by ‘say[ing] with confidence that at least one in every 30 men has sex with a sex worker during any given year and there are some indications that the true figure is substantially higher’.

Sex workers and their clients do not constitute a ‘discrete’ section of the population. They are members of the general community. Consequently, sex work-related laws, regulations and practices are relevant to general practice and to health care professionals’ duties regarding the sexual transmission of HIV. In that context, it is important to note adoption at a very high-rate of safe sex practice as an occupational health and safety response in the Australian sex industry, and consequently the minimal risk of HIV transmission at a population level.

Sex work laws and regulations are state based with assorted sex work practices variously decriminalised, legalised or criminalised across different jurisdictions. Some legislation is enforced: other is infrequently applied. Importantly, in addition to sex work related laws, HIV-related laws relating to non-commercial sex also usually apply to sex during commercial sexual encounters.
