In 1971-72 the first diving Nullarbor Caves Expedition took place with Phil Prust, Dave Warnes, Ian Lewis, Bob Lea, Bob Turnbull, and Ron and Denyse Doughton from Sydney. The divers were supported by dry cavers from CEGSA, WASG, Rover Scouts and others. A total party of about 60!, although not all were out on the Nullarbor at the same time.
