The people all over Australia are the same, with small differences that distinguish them from the peoples of the other states. The Queenslanders are extremely relaxed and friendly, much like Western Australians, although I think even more so, because of the added humidity.
Queensland is sub-tropical in the Capital city and region, and tropical in the North of the state. It is quite an amazing place to travel around.
Enjoy your 'walkabout'.
