Hasn't happened in Australia but it did in Singapore many years ago.

A Chinese freelancer from the now defunct OT.

It was a "long time" arrangement but after doing the deed and then sleeping, she woke at some stage, quietly dressed and exited the hotel room taking US$500 (circa 2007 $s) from my wallet as she left.

Never happened again, but for many years I always locked watch, wallet etc in room safe when I had a girl in a hotel room .....
