you should check out qantas for your airfare - although they have a reputation for being a little pricey, they have some great US - Aust airfares. eg $999 west coast return including 3 flights within australia. plus their inflight service is so much better than any of the US airlines. (you can also add a stop in fiji for $100 - bargain) Should you decide to go to Melbourne (my home town) the Lonely Planet guide is pretty good.
