Amazon not supporting Australian Authors

I have prepared an electronic edition of my "Green ICT" book for Amazon.com's Kindle e-Book device. Amazon.com are now offering an international version of the Kindle for use in Australia. So it seemed a good time to publish. But after carefully formatting the book and uploading to Amazon's Digital Text Platform web site, I found I was not able to publish without a US bank account and US tax information. I am already registered as an Amazon Associate and receive cheques from Amazon. But the Australian address and Australian tax details which are acceptable for Amazon Associates appear not to be acceptable for Kindle. The result would seem to be that only US based publisher will be permitted to publish with the Kindle. This is unfortunate as it makes the device unsuitable for educational use. I attempted to get around this by seeing if LuLu.com had an arrangement to publish on Kindle, but they don't.
