While diving the Great Astrolabe Reef, take the time to enjoy the healthy coverage of hard and soft coral. Sponges, sea whips, sea fans and giant clams crammed on to coral bommies make for a wonderful sight. Manta rays are a highlight at Kadavu and they often frequent cleaning stations at the southern part of Kadavu Island. As such expect to see many colorful butterflyfish and cleaner wrasse at these sites.
Amongst the pinnacles, passages and along walls, you are likely to bump into friendly green sea turtles, humphead wrasse and also large and sometimes inquisitive potato cod. Schooling fish like sweetlips, snapper and fusilier are also common and these attract hunters like giant trevally, mackerel and tuna. At a dive site called Seafan Alley, there have been sightings of hammerhead sharks but usually at depths below 100ft (30m).
