Geeze thats expensive, I just cant see it being that much for postage, there's this one.
it would be 52.80aus to my door. Purely guessing I cant see it being more than 50aus to get over, I would think that 50aus postage as the extreme cost, but cant guarantee of course. If you cant find one over there, I'm happy to help you out to try and get it cheaper. Its probably the weight of the thing.
