first thing i would do is read up on the NSW Brothel Regulations,
than check with local council regulations
than make shore you meet all the regulations before you apply for a licence,
also i found out a Small (1 or 2 sex workers) brothels are exempt from holding a licence but must register with the BLA and hold a local council planning permit. Advertising is legal with the licence number given by the BLA. Operating an unlicensed brothel and soliciting in a public place are illegal. local council planning approval.7 Aug 2015
that's why you find a lot of massage shops next to train stations only have 2 girls working.
lets look at the negatives, girls not turning up to shifts, extortion from gangsters, violent punters, getting robbed, constantly being inspected to make shore you are not breaking any of the regulations and getting fined or shut down.
in terms of the business being profitable for the owner, it depends on the set up costs, rent, and daily expenses, location and compertition,
also dealing with the girls mentality when they don't want to sleep with a punter but complain they don't make any money.
in terms of the business being fun and games, i think the novelty will wear off very quickly especially when it comes down to your financial future being put at risk,
so overall i can think of other business to set up without the dramas,
