Adelaide Technical Diving

Adelaide Technical Diving specialises in technical training, which in South Australia connects directly to one of the most significant diving regions in the country: the freshwater caves and sinkholes of the Lower South East.

Mount Gambier is internationally important for cave diving, and there is nothing comparable elsewhere in Australia. The limestone of the region is riddled with water-filled caves and sinkholes — Kilsby's, Piccaninnie Ponds, Ewens Ponds, Tank Cave and many more — with water clarity that can exceed anything in the ocean.

It is also the region where the gap between recreational certification and the qualification actually required is widest. A standard Open Water, Advanced or Deep certification does not prepare a diver to enter an overhead cave environment, and no amount of open-water experience substitutes for cave training. Caves remove the option of direct ascent, and every other requirement follows from that.

Access is governed by the Cave Divers Association of Australia, which operates a site classification system determining which qualifications permit entry to which sites. CDAA membership and the corresponding category rating is generally the mechanism by which access is granted at all — a diver arriving with an international cave certification and no CDAA arrangement will not be diving.

The technical pathway toward cave qualification typically runs through Advanced Nitrox and Decompression Procedures, with sidemount configuration relevant for the more restricted systems.

Worth establishing: the technical agency and maximum course level; whether cave training is offered and how it relates to CDAA categories; the instructor's own qualifications and recent diving; gas support including oxygen, helium and Trimix; whether technical and cave equipment is available for hire; and CCR support including which units.

Anyone considering cave diving should understand that the CDAA system is the mechanism for access rather than an optional accreditation. An international cave certification without a CDAA arrangement generally means not diving, and sorting that out is part of the planning rather than an afterthought.
