I ordered a bunch of supps the other day, including Power Drive. I'm in Melbourne, and it's expected to arrive in the next week, so I guess we'll see if there's any customs problems.
I'm pretty sure it'll be fine because the Australia Biotest website sells it, although I'm not exactly familiar with the actual import regulations regarding it (ie, it dosen't have to be illegal to be seized, just in conflict with certain import laws). shrug
Better to buy from the US site though at the moment, with our dollar at somewhere around .90 it is a god damn bargain.
