I cannot find a reasonable excuse as to why it's going to cost me $400 more to purchase my 512GB rMBP than it would cost to purchase it in the US. Some people say currency exchange buffers, smaller population, GST, or other tax/levy related reasons, but the only thing that really makes sense is that we as Australians will pay this "Apple Tax" regardless, and so they rape us with it. As it stands, I can't see a way to circumvent this without having either delivery or warranty concerns, and without being stamped with some sort of an import fee or tax for trying to purchase it from the US. If anyone has experience with this, or a better explanation as to the why, then please shine a light on it. Cheers.
