Great Astrolabe Reef

[1] The reef is a breeding ground for many large billfish (marlin) species, sharks, tuna, giant trevally, mahi-mahi (dolphinfish) and snapper, due to it having many channels leading from extremely deep water into shallow lagoons.

This is because Naiqoro Passage is one of the main thoroughfares for large fish.

The marine lagoon ecosystem of the reef contributes to its national significance as outlined in Fiji's Biodiversity Strategy and Action Plan.

The reef is a great location for experiencing marine life and coral diversity, being relatively unspoilt due to its distance from dense population.

The water temperature varies from 25 to 32 degrees Celsius, making it ideal for snorkelling and scuba diving.
