Meet the site
Longnose Reef combines a shallow inshore reef with a seaward drop-off. The Marine Life Network describes it as a 5–30 m site with 'shallow inshore reef and seaward drop-off' and places it on the west coast, while Oceanatik puts it off the northern coast and describes wall and reef 'rich in hard and soft corals' with abundant marine life – 'a very exciting dive with lots to see and explore along the walls'. Oceanatik notes that because of depth and mild currents, beginner divers should dive with instructors or groups.
The structure gives divers a choice. The seaward wall is where the depth and the bigger fish are, with hard and soft corals, sponges and sea fans on the face and kingfish, trevally and other pelagic fish in the blue. The inshore reef is shallower and easier and suits the second half of the dive. Norfolk's reef fauna – groper, morwong, rock cod, moray eels, wrasse, butterflyfish, parrotfish and emperors – is spread across both.
The location discrepancy is unresolved: 'north' and 'west' may both be loosely right if the reef lies on the north-west corner of the island, near Anson Point. Either way, the reef is dived by boat and would normally be sheltered in the prevailing south-east trades and exposed to northerly or westerly swell.
It suits Advanced divers comfortable on a wall to 30 m in mild current, and Open Water divers on the shallower sections with a guide. With no chamber on the island, keep the deep section short and plan conservatively.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Longnose Reef is recorded as Wall in Norfolk Island. The listed access is boat (day trip). Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.
Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.
- Current and timing
- Ask how the operator assesses the current window for the actual route. Historical tide notes are not a departure instruction.
- Planned depth
- Confirm the intended route and training requirements; the recorded maximum is not a target.
- Water movement
- Ask how swell and local exposure affect the proposed entry, exit and route.
Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.
Questions, answered
Is Longnose Reef suitable for my certification?
The record lists Advanced Open Water. That does not establish suitability for every route or day. Share your training, recent experience and equipment needs with the operator and ask about the specific proposed dive.
Can I book Longnose Reef through YouDive?
YouDive is an independent research directory. Contact an operator directly to confirm whether it currently runs the trip, the inclusions and the booking terms.
