When Amazon last upgraded its Kindle range, it wasn't surprising that the Kindle Fire didn't ship here, given its heavy integration with US-specific services. It was more annoying that the Kindle Paperwhite wouldn't ship here either, but that has now changed, as Amazon appears to be happily shipping the Paperwhite to Australia.
The new shipping arrangement was spotted over at OzBargain, although it appears a little inconsistent. I was able to place an order for a Paperwhite to ship to Australia, but Lifehacker editor Gus wasn't (and nor was Luke over at Gizmodo. If you're keen on the Paperwhite, the base model (including standard shipping) will cost you around $150 at current exchange rates.
