I don't know what stores they have in Australia, but I know here in the States you can go down to drugstores (CVS/pharmacy is the one I worked at) and buy one. You have to buy the kit, provide what they need for it (I'm guesing like hair folicles or something) then send it in. The thing is, to send it in and get results, you need to send them like.. $130 or something. It's not cheap, but depending on why you are getting it, well worth it.
