After riding my mountain bike from Adelaide to Darwin in 2005, I was keen for another such adventure, but one that returned to the kind of back roads I travelled when riding from Sydney to Melbourne in 2004. I hatched the idea of riding from the southernmost tip to the northernmost tip of mainland Australia, and rather than riding along the main (coastal) highway, try and ride a straight-line route that would necessarily take me on back roads and through a variety of terrains and climates.
