Site Overview

Rimatara is the most remote and least dived island in the Austral archipelago, offering genuinely exploratory diving opportunities where every dive may reveal new species and habitats in an underwater environment that has been virtually untouched by human observation. The island's small lagoon supports coral communities and fish populations that have evolved in isolation from the other Austral Islands, potentially harbouring endemic species found nowhere else in French Polynesia or the wider Pacific. The exploratory nature of diving at Rimatara means that each dive carries the genuine excitement of discovery, with divers potentially observing marine life and reef formations that have never been documented by scientists or underwater photographers. Nudibranchs and other small invertebrate species may represent undescribed populations unique to this isolated lagoon system, making the site particularly interesting for marine biology enthusiasts who appreciate the opportunity to observe organisms at the frontier of scientific knowledge. Moray eels, parrotfish, and green turtles inhabit the lagoon in healthy numbers, indicating a productive ecosystem despite the island's small size and isolated position at the southern extreme of the Austral archipelago. The sense of genuine exploration and discovery at Rimatara is unmatched by any other dive site in French Polynesia, offering a truly unique experience for divers who value being among the first humans to observe an underwater environment.

Dive Briefing

"Descend from the boat into the small lagoon of Rimatara with the exciting awareness that you may be among the first divers to explore this underwater environment. The coral communities and fish populations have evolved in isolation, potentially harbouring species and ecological relationships not observed at other dive sites. Search carefully for nudibranchs and other small invertebrates that may represent endemic populations unique to this isolated lagoon system. Moray eels occupy crevices throughout the reef, with some individuals showing little fear of divers due to the absence of previous human contact. Green turtles visit the lagoon to graze on the limited seagrass and algae resources. Parrotfish and other reef fish patrol the coral formations with their characteristic behaviours in an environment where they have never experienced diving disturbance. Document your observations carefully as every dive at Rimatara contributes to the limited knowledge base about this remote island's marine environment. The exploratory nature of the diving requires careful attention to safety as conditions and hazards may not be well understood."
