1973. At the time, cave diving was not regulated and training, if any, was rare. As a result, there were a number of fatalities. To address this concern a group of dedicated individuals formed the CDAA. The CDAA introduced standardised training, and working with the landowners and government, regulated site access to those that were trained. This had an immediate impact on cave diving and the ceasation of incidents being observed. Since that time the CDAA has had enviable record of safety in cave diving, standing out as a world leader in safety and education in the field.
