Vodafone Australia just confirmed on their blog that the Nokia N9 is coming to their network. The price is still not yet known, but expect it to be at the €299 level, or maybe even less if you will get it on a contract.
Vodafone Australia will carry the 64GB variant of the N9, only in black color. No words yet on other colors and on the cheaper 16GB variant. If you're living at Australia you can sign-up now so you will be notified if the N9 is already available.
