Cave Diving

Australian cave diving and the CDAA
Australia has many spectacular water filled caves and sinkholes, but unlike the UK, most Australian cave divers come from a general ocean-diving background. The "air-clear" water of the sinkholes and caves can be found in the Mount Gambier area of south-eastern Australia. The first cave and sinkhole dives here took place in the very late 1950s, and until the mid 1980s divers generally used single diving cylinders and homemade torches, and reels, resulting in most of their explorations being limited.
A series of tragedies between 1969 and 1973 in which 11 divers drowned (including a triple and a quadruple fatality) in just four karst features - "Kilsbys Hole", "Piccaninnie Ponds", "Death Cave" and "The Shaft" - created much public comment and led to the formation of the Cave Divers Association of Australia (CDAA) Inc. in September 1973. As a consequence of the CDAA's assessment programs, divers are rated at various levels, and today they comprise Deep Cavern, Cave, and Advanced Cave.
