La Foa and Ouano

Use a qualified, insured operator and request proof of current licensing and the actual boat safety plan. Clarify accepted certification, supervised versus autonomous status, age limits, medical form or certificate, oxygen availability, communications, diver pickup, emergency procedures and insurance exclusions. For N'Digoro reef, confirm the exact route against the provincial protected-area boundaries. The integral reserve prohibits entry and activities within its boundary, not merely camping or landing; a similarly named advertised reef dive does not override those rules. Passes may involve current and route swaps. Avoid independent deep freediving, unplanned overhead exploration and swimming into boat channels. Use a trained safety buddy for breath-hold activities; never hyperventilate. If symptoms occur after diving, stop activity, give first aid according to training, seek urgent medical direction via 15/16 and let rescuers coordinate recompression and evacuation. Plan no-fly time with the operator and current diving-medicine guidance.

New Caledonia's main public hospital, CHT Gaston Bourret at Koutio Medipole in Dumbea, provides major emergency care, while medical facilities outside Greater Noumea can be limited. Australian Smartraveller (updated August 2026) identifies the decompression chamber available in Noumea as SCADEM, and SCADEM's own site advertises hyperbaric services. That information does not verify chamber staffing, operational readiness or response time for a specific trip. Recompression and evacuation should be directed by emergency medical professionals, not by tourists. Insurance should explicitly cover scuba, recompression, hospital treatment and transport, including possible long-distance repatriation. Record the shore emergency contacts before departure.

The UNESCO West Coast lagoon system and Province Sud protected areas include sensitive reef, seagrass and mangrove habitats. The provincial islet dataset states that N'Digoro islet is an integral reserve with access strictly forbidden. The wider Ouano nature reserve, which includes Konduyo, has no fishing, hunting or collection of wildlife, plants or minerals, with other activities governed by the environmental code. Do not collect shells, touch coral, feed animals, anchor on living reef, fly a drone without checking rules or assume camping is legal everywhere because a public beach advertises camping. Seek customary permission for non-public Kanak land and use locally approved paths and moorings. There is no evidence of an open-to-tourists whale-swim program here. The integral reserve's mapped boundary also matters for water access and activities. The provincial lagoon guide describes associated reef habitat; do not infer permission to enter it from the similar name of an advertised dive route.
