Guardian Dive Network
The divers who see these wrecks first
Dive centres and divers visit the wrecks every week. The network gives them a way to report what they see, and gives the platform eyes on the seabed between surveys.

Why divers matter
Thousands of eyes on the seabed
A field survey visits a wreck once. Recreational divers visit the same wrecks all year, and they are the first to notice a change: a new sheen on the surface, a collapsed section, an exposed shell, oil in a compartment that was clean last season.
Those observations are exactly what the platform needs between surveys. A report with a photograph and a general location reaches an analyst, is checked, and can update the wreck's record. Divers do not score anything, and no report changes a number on its own: it goes into the evidence an analyst reviews.

Salt PNG
Rabaul, East New Britain, Papua New Guinea
Dive operator in Rabaul and Guardian's partner on the October 2026 deployment.
Featured partner
Salt PNG, Rabaul
Salt PNG dive Simpson Harbour every week and were Guardian's partner on the ground in October 2026: finding targets, reading conditions and diving alongside the survey team.
Together we are putting together a wreck trail of the harbour's recreational-depth sites, with the history of each vessel and the observations divers can make on it. Trail details and booking will appear here.
Report a sighting
Seen something on a wreck?
Use the diver report to tell us what you saw: the wreck or general area, the date, what you noticed and a photograph if you have one. No account is needed. Affiliated centres can give you a report link that pre-fills the site.
Every report is reviewed by an analyst before it touches a record. If what you saw looks like an active release, we also tell the responsible authority.

Diving these wrecks
Most of the wrecks in the network are war graves and many still carry fuel and munitions. The code is short and we ask every affiliated centre to brief it.
- Look, do not touch. Take photographs and notes. Leave every object where it lies. Nothing is recovered from a wreck.
- Leave ordnance alone. Shells, bombs, depth charges and ammunition remain dangerous after eighty years. Do not touch, move, tap or lift anything that could be ordnance. Note where it is in general terms and report it.
- Stay outside. Do not enter hulls, holds or compartments. Structure that has stood for decades can fail without warning, and the remains inside deserve to be left in peace.
- Mind your buoyancy and your fins. Silt, corals and corroded plating are all easily damaged. Keep off the structure.
- Do not anchor on wrecks. Use moorings where they exist. Anchors and chain do more damage to a wreck than any diver.
- Report what changes. A sheen, a collapse, exposed cargo or ordnance, or anything that was not there last time: report it through the diver report the same week.
