OS X Lion is out in Australia, and it comes as standard on all Macs from now on. It's a cheap upgrade for anyone with a pre-existing copy of OS X Snow Leopard, costing only $31.99. It's a 4GB file, and Apple is advising users without broadband to bring their computers into an Apple Store to download the software wirelessly.
