Queensland is cool you got great beaches the great barrier reef, lots of sun, tropical rainforest. Cairns by itself is not that interesting but a good place to get information and organize further traveling.
Favourite spots:
Witsunday Islands The Great Barrier Reef Fraser Island
What's really great:
4 Wheel Driving on Fraser Island and north of cairns snorkling at the reef and sitting in a pool at christmas and having a cool beer
