Cave Divers Association of Australia
CDAA Diving Courses in Australia
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.

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.

CDAA Course FAQs
What does CDAA stand for?
CDAA is Cave Divers Association of Australia. Its documented programme areas include deep cavern, sinkhole, cave, advanced cave / penetration, site-specific access endorsements.
Can a diver with another agency continue with CDAA?
Previous recreational or technical training may satisfy prerequisites, but the receiving CDAA instructor must review the exact certification, experience and current standards. Ask before assuming two similarly named levels are equivalent.
Does every CDAA centre teach every CDAA course?
No. Facilities, instructor ratings, equipment and local sites differ. Verify the specific course and instructor rather than relying on agency affiliation alone.
How should I choose a CDAA instructor in Australia?
Compare recent teaching and diving experience, class size, site choice, equipment, total course schedule, assessment standards and support after certification.
