Cave Divers Association of Australia
CDAA
Not a general training agency — the body that governs cave and sinkhole diving access in Australia.
The CDAA occupies a different position from the other organisations on this page. It is not a general recreational training agency but the body that governs access to Australia's cave and sinkhole sites, principally in South Australia's Lower South East.
It operates a site classification system, and a diver's CDAA category determines which sites they may enter. Membership is generally the mechanism by which access is granted at all.
The system exists because of a history of fatalities in the region during the 1960s and 1970s, and its rules are specific responses to how those incidents occurred.
| Full name | Cave Divers Association of Australia |
|---|---|
| Programs | Deep Cavern · Sinkhole · Cave · Advanced Cave / Penetration · Site-specific access endorsements |
| Strengths | Governs Australian cave site access · Site-specific classification system · Local knowledge of Australian karst systems · Recognition arrangements with international cave agencies |
Overseas cave qualifications are recognised by CDAA for equivalence in certain categories, but site access still runs through the CDAA system and landowner permissions.
A diver arriving in Mount Gambier with an international cave certification and no CDAA arrangement will generally not be diving.

- why local rules exist and what they are responding to
A standard Open Water, Advanced or Deep certification does not prepare a diver to enter an overhead cave environment, and no amount of recreational experience substitutes for cave training.
This is the single most important point the CDAA system enforces.
