Aims and Objectives

We foster the development, advancement, promotion, mapping, education, exploration, conservation, safety and research of underwater caves and related features.

Before 1973, cave diving in Australia 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 in September of that year. Today the CDAA has grown to be a world leader as it drives excellence in cave diving always innovating with new equipment and techniques to continually improve the safety of the sport and its members.

Incorporation

The CDAA is an Incorporated Association under South Australia law with a Constitution upheld by a National Committee of five directors.  National Committee positions are appointed by membership vote on a bi-annual basis.   The Committee appoints State Representatives and Office Bearers for various roles critical to the smooth running of the Association.

Membership

New membership is available to all qualifed Advanced Open Water divers who are accepted for the CDAA Deep Cavern (entry level) certification. An annual fee is payable to maintain membership status.

    In the worse tragedy in world cave diving experience equalled only once by a similar multiple-drowning the USA, 4 divers drowned in the most renowned sinkhole of Mt. Gambier, a cave called The Shaft. Consisting of a gigantic rock collapse chamber 120m deep and probably 200m in diameter or more, it magnitude and visibility (100m+) draws divers from all over the world.  One visiting group was a party of 9 divers with a plan for 8 of them to descend to 60m.  On this dive four divers did not return, running out of air.  At extensive inquest was held with much media attention.

    At the time, this multiple drowning was the worse in cave diving history in the world, and its repercussions caused a great deal of self-examination by diving clubs throughout the country.  October 1972 long weekend saw a large Adelaide Dive Club run a trip to Mt. Gambier to dive various sinkholes.  Four divers entered a cave, without a guideline and adequate equipment, the silt was stirred up transforming the clear water into impenetrable back within minutes.  The group became disoriented, three divers drowned and one only just made it out before running out of air.
