Wrong - most deserts of Australia don't have any 3G access. But anywhere in Australia with 3G access (i.e. populated areas) all have the same data tariff, which is comparable to the US price.

How do you know the details of AT&T's roaming agreements with Australian carriers?

I know you don't, because your statement is 1000% incorrect.

I would assume Amazon can negotiate with local carriers in each region, rather than paying through a US carrier for data sent to Australia.

That would require a magical sim swap while the kindle is in transit.

Where did you read that? On my reading of the terms (and being an AU resident) I'm pretty sure whisper net doesn't exist in Australia.

Which would also suggest you don't get charged a delivery fee to AU customers..?
