The only real ones still working afaik are the ones based in Queens Park and you can spot them on Locanto. There's one that does RnT only and another that does FS. I've tried both and it was bad service. There was once some great Indian options, Teena was good but has left the industry, Anu I didn't get to try but apparently she was good according to reviews, but she's based in Melbourne now.
As a guy with an Indian fetish the scene is very dry in Perth at the moment.
