I'm in Melbourne at the moment, but by November I'll be living in Perth (much to my wife's displeasure - her family is in Melbourne)
I have a friend in Perth who details for a living. He says he gets too much work to handle. I haven't seen his work, but uses a rotary and Autoglym polishes...seems to know his stuff. He charges too little for my taste - rotaries work fast. I mainly use a PC. His business is called HiShine.
