Sex work is legal/decriminalised in Sydney. If you come from a country where it is illegal, you might be surprised how open it is around here. And right next to family friendly establishments, residential areas.

It's pretty safe actually. Or at least no more dangerous than other parts of Sydney. I've never heard of any crimes or violence related to sex workers in Sydney. I'm more worried about alcohol and drug related violence. If there are any unsavoury characters about they are much more likely to be at a night club. Ban night clubs (they kind of did that https://en.wikipedia.org/wiki/Sydney_lockout_laws and it worked).
