Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from web research (Oct 2026): the Cave Divers Association of Australia (site list, site pages, training and visitor permit), Parks SA, Forestry SA, Wikipedia, the heritage summary of Fossil Cave, cavediving.net.au, CDG reports (caves.org.au), Divernet (2025), the City of Mount Gambier, the Royal Adelaide Hospital, DAN and the dive shops' own websites. Pins only where Wikipedia gives coordinates; the CDAA publishes none. The certification per site is an estimate from the CDAA rating; you always need that CDAA rating as well. Check everything with the CDAA.
