This episode the crew re-traces the steps of David Norrish. In 1974, when northern Australia experienced a once-in-500-year weather event, and the river flow from such heavy rainfall caused Lake Eyre in South Australia to fill with water, Norrish packed a boat on the roof of his Kingswood and set off for a spot of outback sailing. The first celebrity in this new season is Lisa McCune. Steve explains the changes they've made to the test track, and Shane Warne drops in for a high-speed blast in the Morgan Aero Supersports.
