If you are traveling to Perth. Look for a placed called 'SECRETS'. It is located opposite Westfield Carousel. Rent a car if you are planning to stay in Perth for more than 4 days. This places has ladies from Thailand to Korea.. Similar to geylang, but the ladies will come out and intro themselves to you by saying their names. Remember the lady which u want and just let the boss know which one u want. Price is $130 for 30mins and $200 for 1hr.
If you want to do your own research and look around then go to this website:
