Kusu-side outer reef with sharks, rays, and reef life
Kusu-side outer reef with sharks, rays, and reef life
Nabucco Outer Reef 3 sits in the Kusu Island side of North Maluku, where reef structure, coral heads, and tide movement shape the dive more than any single landmark. It offers a wide spread of sightings, including eagle rays, blacktip reef sharks, nudibranchs, clownfish, jackfish, scorpionfish, lionfish, snappers, parrotfish, triggerfish, boxfish, shrimps, ghost pipefishes, and leaf scorpionfish, so the draw is a balanced outer-reef profile with both big and small life.

Depth range, seasonality, and planning context.
Reported Depth
0m - 30m
Depth Note
The island reef starts shallow and can run into mid-depth water; the operator FAQ caps local diving at 30 m and treats the area as no-deco recreational diving.
Best Season
Year-round, with calmer weather outside the wetter December-March window.
Typical Conditions
Warm, clear tropical reef water with a current-aware outer-reef feel; the site is best when the tide window is gentle and the crew can keep the route conservative.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Keep a close buoyancy check over the coral blocks, and treat the dive as current-aware even when the surface looks calm. This is not a site to force if the tide is running harder than briefed.
Access Restrictions
Confirm current operator permission and the day's entry method before you go; older resort-era access arrangements may no longer apply.
Legal Notes
A former island resort operation closed in 2026, so current access and permissions should be checked locally before travel.
Community notes to help plan your visit.
Scuba Diving
Best for guided reef diving with tidy buoyancy and a willingness to adapt to the tide. The appeal is the mix of outer-reef structure and a very broad species list rather than a single marquee feature.
Freediving
Not a freedive-first site. The current-sensitive outer reef and coral relief make it a better scuba dive than a casual breath-hold stop.
Snorkeling
Casual snorkeling is only sensible in the calmest shallow water and only if a local operator says conditions are suitable. The outer-reef edge itself is better left to scuba.
