We visited Australia a few years ago. My favorite was visiting Brampton Island on the Barrier Reef. It was paradise and a great location to swim and snorkel. We stayed in Sydney a few days and stayed at the Intercontinental...loved it. A great experience was to get up REAL early and head to the Sydney Opera. What a great time running up and down the steps (ok..I'm from Philly and do my Rocky imitation!) with no one around. BEAUTIFUL. We visited Cairns and enjoyed it even though it was rainy season and there were TONS of jelly fish so you could only swim in netted area. Australia is beautiful!
