first @ all,
you need to go to "Magistrat Ordnungsamt/Gesundheitsamt", to get your "Health Book".
You need to Visit the Doctor all over Austria every 6 Weeks!
In Tirol and Salzburg it's only allowed to work in approved Clubs. If you work on Street, Hotels, Apartments without Licence you will get abused by the authorithies. (It starts from 1050 €, if you work intent with healthbook illegal it will start about 3000 €) (Theres just one approved Apartment in Salzburg it's called Sterneck57)
The Rules in Bavaria are kind of same like in Austria, except you can work in Austria without Condom.
Actually the Hotels and Appartments will be checked by the Police. They scan some sites on the net for Ads, will make up a meeting and give you an sweet, little, nice, expensive punishment!
Special 2-3 Hotels in Salzburg, if you check there in, the personal will give some tips to the local police.
If i can say about the last years in Salzburg:
The normal stay of Girls in some Hotels is under 4 Days. The most of them got problems, and also the most of them with problems where caught in the act with clients! The Abuse for the Clients is also still High (starts between 360 and 500 €).
And the biggest problem in Salzburg actually are other Girls (Romanians, Hungarians, Croatians), witch are working for such low prices that most of Hookers which i know, never will come back again to Salzburg or IBK.
The Prices in Salzburg are since i know (about year 2000), roundabout 150 € for 1h. Extras like Anal starts from 50, kissing was an Extra and so on.
Now (2016) the average Price is 120 € for 1h. You will get really complete Service (including Anal, bareback, swallow and so on for 150 €, but most of girls need the money for their pimp so it's easy for customer to get all inc. also for 120-130 €).
Please, forget about Salzburg or IBK. IBK it's kind of interesant in some clubs with italian clients. I would suggest or prefer Kärtnten (Next to the Italian Border, some good clubs, higher prices for Girls).
If you got any question than -> PM
Good luck at all
Ps. Sorry for my Bad german english
