Because of its large size and weight, even disassembled, it is extremely expensive. I don't have an account with anyone so the cost definitely wouldn't be worth your while. I've gotten estimates ranging from $600-$1300 which is ridiculous.
When i bought this a few years back, their website somehow let me check out and it allowed shipping to U.S.
They later contacted me saying they don't ship to the states because of its weight. I understood this but pointed out that it wasn't my problem their system allowed an international transaction. They tried to refund me and I insisted they needed to fulfill the order and eat the cost for the shipping. After some more back n forth, they accepted fault and shipped it out to me. Couple of years ago, I looked into getting one for my Dragster and at the time, they weren't shipping to U.S.
I know you're in Australia but I'm assuming they still don't ship internationally.
