In August 1925, two young adventurous missionaries set off from Perth, Western Australia, in their small Citroën with a plan to drive to Darwin, selling books and collecting donations along the way. If they made it that far, they would be the first motorists to complete that journey. But adventure took on a life of its own and, by the end of the year, Nevill Westwood and the little car 'Bubsie' had driven into the history books and completed the first journey around Australia.
