I'd just like to point out the terrificness that is Brisbane!! People from overseas who want a city experience tend to head to Sydney and Melbourne - but Brisbane has got just so much to offer (Ok - I live here so may be a little prejudiced).
Brisbane is the capital of Queensland - and is situated about an hour drive from both Gold and Sunshine Coasts (two of Australia's most famous beach areas) and on the way to both are terrific Theme Parks (including Steve Irwin's Australia Zoo on the way to the Sunshine Coast).
From Brisbane, you can catch our Travel Trains and tootle either up the coast all the way to Cairns or head out west to some of Australia's most famous outback towns.
Brisbane also has the world famous Lone Pine Koala Sanctuary - which has a bus route right to the door or you can catch a City Cat and head there via the Brisbane River.
South Bank is the location where World Expo 88 was held, and is now a parkland right on the river, with some terrific restaurants and cafes as well as a swimming beach (yes - in the middle of the CBD). The Gallery of Modern Art and Queensland Museum are across the road from South Bank and are also worth a visit. And if you like Museums, in our City Hall, the Museum of Brisbane has some very Brisbane-centric displays.
Brisbane has some great Aussie colonial buildings and is one of the most haunted cities in the world - if you are into ghost tours, Brisbane has a very long running series of tours that takes in Toowong Cemetary, Boggo Road Jail and many of the old buildings in the CBD.
Please - don't forget Brissy! We're a freiendly and welcoming mob who just love visitors!
