'Cliffs, sudden death and sharks on the right; poisonous snakes, spiders, lethal kangaroos, dingoes and, of course, thekiller wombats on the left.'These are just some of the challenges that face Geoff Hill and Colin O'Carroll as they set off on their Triumph motorcycles for an epic adventure around Australia's legendary Highway One.Over fifteen thousand miles long, the road circumnavigates the country, taking Geoff and Colin through major cities, busy holiday resorts, dramatic coastlines, tropical forests, scrublands and across the Nullabor Desert, to come full circle and end up in Adelaide ... exactly where they started.But this is not just the story of their inspiring and hilarious journey, this is the extraordinary story of Australia itself, told through a motley cast that includes Captain James Cook, Crocodile Dundee, folk hero Ned Kelly, legendary explorers Robert Burke and William Wills, countless immigrants and settlers and an unreliable camper van called Matilda.
