Hey you can visit Sydney. That's where everyone goes. The city is actually a nice place and very tourist friendly. Circular Quay and Darling Harbour are beautiful. Choose the time of year when they light up the Harbour Bridge and it's wonderful. You can take a ferry to get to most of the places along the water. If you want the koala/kangaroo experience check out featherdale park or symbio. You'll need to rent a car but it's a really nice place where the kangaroos come up to you for food and to be petted. Some just lay there lazy and don't care lol. You also get to take a pic with a koala I didn't get to see much of Sydney(I lived in the boonies) but when I did get out and see the ocean and all the fun places to go it was nice.
