Down Under Magic is a fascinating story of one man's love of the ocean and how it led to the foundation of the Black Rock Underwater Diving Group - one of the first SCUBA clubs in Australia's history. From this band of friends came the Associated Divers Academy. The struggles, the temptations, the risks taken with limited knowledge of the consequences of breathing underwater, make for absorbing reading. This book documents for the first time the early history of skin and SCUBA diving in Victoria and Southern NSW. It shares too, how the first single-hose regulators in the world were constructed near the same time, by the talents of two Australians Lionel Martin and Ted Eldridge. Bill has inside information on how Prime Minister Harold Holt disappeared. Down Under Magic contains photos of Bill with the Pime Minister before his disappearance off Cheviot Beach on December 17, 1967.
