Firstly - New South Wales. What it doesn't mention is that NSW is more than just Sydney - and that the legislation has proved to be difficult for country towns and larger regional towns. Nor can they ban brothels all together - they must put in place a brothel policy that allows for brothel development in some capacity. What this means in reality is that they often make it really difficult for brothels to meet standards etc. As far as making money goes - Sydney is a good place to work for sex workers.
Police have no control over the industry.
16 Brothels in Canberra and about 20-30 privates working in any week. Unfortunately, only some brothels are legal, so this has created a two-tiered system whereby there is a small legal industry and a HUGE illegal industry, including street workers. Most street workers can be found in St Kilda, where the sex worker rights organisation is also found. The South Australian sex workers have been lobbying for law reform for years, but still a viable legislative system has yet to be developed by policy makers. This is an occupational health and safety issue that makes a mockery of South Australian government's stated committment to reducing the spread of HIV and other sexually transmitted diseases.
