The Basic Cave Diver Program is the amalgamation of skills and knowledge necessary to safely dive in Cavern and Sinkhole rated sites. Training covers areas that may have zero visibility and the potential for unlimited visibility.

Basic Cave training consists of the equivalent of five full days of theory and diving.


Cavern Site   

Defined as body of water which has a maximum depth of 20 metres, slight overhangs, near vertical ascents and where daylight is always visible (eg limestone caverns, dams, flooded quarries, lakes etc). The maximum linear penetration allowed is 40 metres from the surface.


Sinkhole Site 

Defined as a body of fresh water which can have large passages (no restrictions too small for two divers to swim adjacent to each other) and which exceeds 20 metres in depth. The maximum linear penetration into overhead areas allowed is 40 metres. The CDAA recommends a maximum depth of 40m on air.



Before commencement of a CDAA Basic Cave diver training program the candidate must:

Must have held an Open Water recreational SCUBA certification for at least 12 months and have Advanced Open Water recreational SCUBA certification or an equivalent approved by the National Committee.


Have logged a minimum of 50 dives (post Open Water level) totalling a minimum of 25 hours, including at least two night dives and five dives deeper than 20 metres.

Be a minimum of 18 years old.

Successfully complete a diving medical statement. If any contraindications are flagged then a full diving medical examination will be required.



Theory includes CDAA history, cave geology, equipment considerations, predive checks and safety drills, buoyancy and anti-silting, communications, reel and guideline use, gas management and calculation, physiological considerations, access procedures, dive planning, emergency procedures, hazards, accident analysis.
