From Cairns, our last stop was Darwin, at the extreme north of Australia, and more precisely the National park of Kakadu (awesome name for our french readers, I know)
The aboriginal Australians have inhabited this area for over 1000 years, and it's a place where you can see part of their culture. It seemed very promising if not for one problem: the wet season lasted a little longer that usual and 90% of the park was still flooded and inaccessible. The good news for us was that, since we only had one day to spend there anyway, the choice was easily made and we didn't have to worry about what to see.
