Attention, Australians!
I have just heard back from my editor, and it sounds like Orion has a distribution deal with Allen and Unwin. That is to say, they should be there in Australian book stores day and date--which I think is October 20th?--so you'll get them at the same time as the Brits. Is there an Australian Amazon? At any rate, look into a bookseller closer to home and save yourself the shipping; you'll be able to get it. Theoretically.
Meanwhile, Americans! It's not sorted out yet, but we're very close to some kind of solution for y'all as well. I told you that if you waited a few weeks, it would (probably) shake out. : )
ETA: Canada, I hear, is still up in the air. Meaning that it'll be settled with the American distribution. Hey, y'all asked.
