John Doyle and Tim Flannery explore Australia's last frontier in an eclectic journey across the Top End from Cairns to Broome. As the national focus shifts northward, the two men, in their inimitable style, examine the colourful past, present and future of the Deep North. Most climatologists believe that while the lower two thirds of our continent will get drier, the Top End will get wetter. Already the source of great mineral wealth and wilderness assets, the North is potentially the nation's well. John and Tim not only explore the mystique of the Top End, but attempt to understand its future in a rapidly changing global landscape.
