So I got a response from KDP Support about ordering author copies, and readers ordering books to Australia.
Proof and author copies are no longer be able to be shipped to Australian addresses. The reason being, to remain compliant with changes to the GST law in Australia, they’ve changed the way KDP authors in Australia access their books on Amazon. Authors can purchase retail copies of their paperbacks at full price through a Global Store option on amazon.com.au. These changes do not affect the ability to continue to list your books on their international sites or have them shipped to eligible non-Australian addresses.
Looks like I might be heading to IngramSpark…
