Navigating through the Australian Outback entrants traverse rugged, spectacular and remote regions of Australia in pre 1985 cars and 4WD support vehicles. While fundraising for a fantastic cause RFDS! The Royal Flying Doctor Service is the major beneficiary of the Oz Outback Odyssey to help them continue their great work providing a lifesaving, invaluable service to regional and outback Australia. The week long event is held annually in July, starting around Adelaide, South Australia aiming to finish in a warmer location with a final presentation night. Entrant numbers are limited each year to keep the group cohesive allowing greater distance to be travelled.
