With the dollaridoo strengthening against its American counterpart, it feels like the price point offered by the local retailers is no longer reasonable.
The advertised price of 699USD/1199AUD seems to me like it's no longer relevant, as the conversion using today's rate comes closer to 900AUD, even if you add shipping and taxes (which might not be relevant seeing how it will probably fall under the 1k threshold), it still seems like we're overpaying a fair chunk.
So is there any reason why I shouldn't just order one from the US and enjoy the sweet savings of a parallel import?
Bad idea.
Australian iPhone get a 2 year warranty from the ACL provisions. This doesn't apply to overseas stock.
As for the pricing by the time you take into account GST (there's no $1k threshold anymore) you're at $1000 AUD. Then there's shipping costs, US sales taxes (if you don't get it from a tax free state), package forwarding costs, potential loss during transit… I doubt you'll get it to AU for under $1100.
Or you just go get 5% off JB cards and buy it with Australian warranty and support for $1140. Or wait for an eBay sale where you can get it cheap and pay with discounted gift cards there.
