There is no australian supplier, i've looked everywhere. You're gonna have to fork out the shipping bill, as am i. Unless you have a mate in the US that could buy it/receive it and then air ship it to you for cheaper.
I bet that's how they make most of their money. Once again, our small economy gets fucked over. They even have a dude in the US who sells only weightlifting belts.. imagine that. http://www.bobsbelts.com?
that's in US currency too so it's going to cost you and i (i'm getting the same one) about 168 bucks.
