You could try Hop Shop Go (hopshopgo dot com). They are a Singaporean outfit with warehouses in the US. I haven't used them myself but my brother bought a chainsaw from the US with them (Yes, he bought a chainsaw online from the US and had it sent to Australia!). I understand they will do repacking and consolidation if you want as well...for a fee. They can also provide a way of paying with a US address for online stores that need a US credit card address as well as a US shipping address.
On another note, I was in Malaysia when the Touch was released and I couldn't get any online retailer to ship to Malaysia since it was only available in Canada and the US at the time, so I got a friend in Toronto to pick one up and ship it to me. Flash forward 1 year, I've arrived in Australia and my KT was acting really weird so I contacted Kobo Support and they did an RMA for my KT. I had to send them a scan of the receipt which clearly said Chapters.Indigo and they gave me an address in Australia to send my KT. So, I don't know if you would necessarily have an issue if there was a need to return your Aura. They may want you to send it to Australia which would be a huge hassle
but at least you wouldn't be sending it all the way back to the US
