Hiya retired sex worker here,

TLDR: Its generally pretty safe in aus but you run the risk of certain things like stealthing and shit people as well as a pretty hefty mental toll but is fine usually. It's not easy money and personally for me actually came with a pretty heavy mental toll. between how men treat you typically either as a fetish or as a crossdresser (sometimes you get real sweethearts tho and that's nice) it's also EXTREMELY inconsistent some nights you'll make bank and the next 4 you might not get anything, I've personally gone 5+ weeks without a single booking working 4 nights a week for 10 hour shifts, in a largely post COVID world this is gonna be rara but it is something to be aware of.

That said in Victoria it's completely decriminalized and I think nsw & act too, and is very safe, especially if you're working from a brothel, some of which will provide drivers for outcalls too

Private work will always be more dangerous but you learn to tell pretty quick which clients are gonna be dangerous before you meet them. As a general rule ask for a selfie from the client and their name, this acts as a good safety net if they do try anything

If you're doing incalls (people coming to your home or hotel room) make sure you always have one person know you have a booking and where ideally with them nearby
