Cave Diving

The CDAA is one of a number of organisations responsible for the administration of cave diving certification in Australia. Mixed-gas and rebreather technologies can now be used in many sites. All cave diving in the Mount Gambier area as well as at some New South Wales sites and the Nullarbor requires divers to be members of the CDAA, whether in the capacity of a visitor or a trained and assessed member.
