I don't know about the situation in Tasmania, but my partner has done some consulting work for a local sex workers' organisation. She says that, compared to other wage labour, the money is very good, but is not improving and there is a high burnout rate/staff turnover --- mostly because of authoritarian management, ambiguous legal standing and non-existent occupational health & safety standards, among other things.
On the latter point, the sex workers' organisations recently had health promotion funding withdrawn, by the State Labor govt, because they had supposedly crossed the line and were "promoting prostitution as a career". As we might expect from a "Third Way" regime --- the premier, Geoff Gallop went to Oxford with Tony Blair and they are still close --- it was a cynical public relations exercise, driven by the gutter media.
The same gutter media, BTW, romanticises and celebrates the "madams", who are, of course, no different to any other proprietor or manager (in the latter case, often a front for gangsters) who is able to operate a laissez faire workplace --- i.e. ruthless.
