CDAA & TDI Dual Certifications

Australia's most recognised Cave Diving related qualifications are from the Cave Diving Association of Australia AKA the CDAA. This is in part due to it's history as it started way back in 1973 and is one of the longest standing Cave Training Organisations in the world. Being a current financial member of the CDAA provides the insurance required to access most of the Cavern and Cave Sites around Australia. CDAA Courses are taught in Australia and recognised world wide.
