Government & Official Region websites
Australia is a large country, similar in size to the entire USA. While the inland or Red Centre is mostly desert, there are many amazing experiences and places to go in the vast inland of Australia. Our coastal stretches and hinterlands are wildly diversified and we also have Rainforests, the best beaches on the planet, the Great Barrier Reef and Ningaloo Reef in Western Australia. There are just so many places to go that we can't put them all here, but we can certainly reccommend a number of the best places to go on your travels.
The best way to find out everything about certain regions is look at the Official Tourism Associations websites.
These pages list many of the major and regional tourism websites in each state.
