On 18 May 2001 Jon Muir walked across Australia with his dog, a Jack Russell Terrier named Seraphine, from Port Augusta to Burketown. It took him 128 days, spanning a distance of approximately 2,500 km. Jon's walk is unique in that he remained self-sufficient for food and water, hauling, gathering or hunting all of his food for the walk. He filmed his journey and produced a documentary entitled Alone Across Australia. Jon has also successfully climbed Mount Everest, and walked to both the north and South Poles.
