BBFS is everywhere all around the world, however in Australia is a bit trickier because you'll obviously be banned by the brothel if asking for it during intro. The only way to know is if you try it one time then ask for it, you'll get rejected a lot but you'll be surprised on how many actually offer it for some extra tip. Maybe if you're a regular who already spent tons of money for a particular brothel, the staff would let you know who can provide such a service but who knows.
