How to React to a Shark?

If you encounter a shark: Stay calm and maintain eye contact Do not turn your back Use a solid object (snorkel, mask, fin) to gently deter it Most sharks will leave when they realise the object is not food

Which Species Are Protected in New Caledonia?

The protection of biodiversity is part of New Caledonia’s very DNA. Sharks, an important species in Kanak tradition and for the ecosystem, have always been part of the Caledonian environment, where people strive to live in harmony with them. Sharks are particularly vulnerable due to their low reproductive rate and are increasingly threatened by global fishing pressure. They are therefore considered endangered today. For this reason, since 2013, all sharks have been classified as protected species in New Caledonia. Fishing, transporting, trading, cutting, holding, or consuming all or part of a shark is strictly prohibited.

Which Sharks Are Found in New Caledonia?

The term “shark” actually covers a wide variety of species in New Caledonia. Biologists have recorded at least 49 shark species here, out of 500 known worldwide. Most of these species pose no danger to humans if left undisturbed. Many of them can be easily observed during a snorkelling or scuba diving trip, including: Blacktip sharks Whitetip sharks Sleeper sharks Lemon sharks Grey reef sharks Shark movements within the lagoon are closely studied by local authorities and environmental associations , allowing the main habitat zones to be identified and marked for sea users. The largest species – including mako, tiger, hammerhead, and great white sharks – are usually found offshore, beyond the barrier reef, and only rarely enter the lagoon. While a few tiger shark incidents have been observed, humans are not their natural prey. The bull shark , however, requires extra vigilance. Some individuals have settled near the coast and can occasionally display aggression towards humans, depending on the circumstances of the encounter. By following these simple recommendations and exercising basic caution, you can swim safely in New Caledonia and fully enjoy our UNESCO World Heritage lagoon and its exceptional biodiversity .

Understanding Shark Safety

in New Caledonia

In New Caledonia, as in many tropical destinations, people and sharks have coexisted for centuries. While a few rare recent attacks have caused understandable concern among bathers, the shark risk remains statistically low. By following local safety advice and simple preventive measures, you can further reduce the risk and fully enjoy the world’s largest lagoon, renowned for its incredible biodiversity and healthy shark populations.

Shark incidents

in New Caledonia

A recent study by HAL-IRD recorded 67 shark-related incidents between 1958 and 2020, including 13 fatalities. Most incidents involved underwater hunters (58.5%), followed by swimmers (18.5%) and board-sports enthusiasts (14%). In recent years, following several attacks, local authorities have been monitoring the situation very closely and have systematically implemented a range of preventive and forward-looking measures to anticipate any risk, such as installing anti-shark protective nets in Nouméa’s bays.

Globally, New Caledonia ranks 13th for shark attacks since 1580, far behind countries like Australia (715 attacks), South Africa (262), or Hawaii (179). This puts the risk into perspective: dramatic events are statistically isolated compared to other natural hazards.

As the lagoon remains healthy and teeming with life thanks to strong environmental protections, it is essential to follow simple rules to avoid “risky behaviour” – actions that could startle sharks, provoke a defensive reaction, or make humans appear like prey.

Did you know? Sharks cause fewer than 10 fatalities worldwide each year, compared to 1,000 from crocodiles, 25,000 from dogs, and 800,000 from mosquitoes!
