The CDAA was formed in September 1973. At the time landowners throughout the Mount Gambier area of South Australia, were contemplating the closure of all holes to diving for fear of legal liability following a spate of diving fatalities in the water filled caves. With the forming of the CDAA, sinkhole divers hoped to prevent the wholesale closure of the dive sites by presenting a united voice in defence of their sport.
