Lomaiviti Group dive sites

Nigali Passage is an advanced dive requiring comfort with strong currents, drift diving, and open-water shark encounters. Most operators require Advanced Open Water certification and a minimum of 50 logged dives. The dive involves a negative entry into current, maintaining position on a reef shelf while sharks pass, then drifting with the current through the passage. Strong buoyancy control is essential to avoid contact with the reef walls. A surface marker buoy is mandatory. Despite the demanding conditions, the dive is conducted as a well-organised drift and the actual passage transit is exhilarating rather than difficult.

Gau Island is located in Fiji's Lomaiviti Group, east of the main island of Viti Levu. The most common way to dive Nigali Passage is aboard a liveaboard vessel operating out of Suva or Pacific Harbour. Several Fiji liveaboard operators include Gau Island on their itineraries. Alternatively, there is a small eco-lodge on Gau Island that arranges diving for its guests. There are no scheduled commercial flights to Gau, though charter flights are available. The liveaboard route is preferred as it provides the most flexibility to time dives with optimal tidal conditions.

Wakaya Passage is located in the Lomaiviti Group east of Viti Levu, Fiji's main island. Access is primarily through liveaboard vessels operating out of Suva or through the few dive operators based on nearby islands. The most popular liveaboard itineraries include Wakaya Passage as part of a broader Bligh Water and Lomaiviti route. There is a luxury resort on Wakaya Island but it caters to a high-end market. Budget and mid-range divers are best served by liveaboard trips of three to seven nights that include multiple Lomaiviti sites.

The manta ray aggregation at Wakaya Passage is most consistent from May to October when cooler nutrient-rich waters flow through the channel. Mantas gather at specific cleaning stations on the reef and are often present in groups of five to twenty individuals. Hammerhead sharks prefer the deeper cooler water and are most commonly spotted between June and September at depths below 25 metres. The combination of cooler water and strong currents during this period makes the diving more challenging but significantly more rewarding for pelagic encounters.

An Advanced Open Water certification and at least 50 logged dives are the minimum recommended by operators working this site. Strong currents are common and can change direction during a single dive. Divers must be comfortable with negative entries, drift techniques, and deploying surface marker buoys. The hammerhead encounters require descending to 30 metres or below where narcosis and limited bottom time are factors. Most liveaboard operators will assess your experience before deciding whether to include Wakaya in your itinerary.
