Meet the site
The rusting hull at the entrance to Heron Island's harbour is one of the most historic vessels in Australian naval history. HMCS Protector was built by Armstrong, Mitchell & Co at Newcastle upon Tyne and launched in 1884 for the colony of South Australia. She was a 920-ton, 180 ft (about 55 m) flat-iron gunboat, and served in the Boxer Rebellion in China in 1900, was present in Sydney at Federation, and in the First World War took part in Australia's first overseas naval operation, escorting submarines during the capture of German New Guinea. In the Second World War she was requisitioned for service in New Guinea but was damaged in a collision with a tug near Gladstone in 1943 and abandoned. Heron Island's developer, Captain Christian Poulsen, bought the damaged hull for £10 and had it towed to the island, where it was deliberately placed as a breakwater while a channel was blasted into the harbour. Today the hull is badly deteriorated; its teak deck has collapsed, and authorities warn against swimming close to it because of sharp edges and falling debris. Ecologically, though, it is thriving: researchers describe the wreck as a haven providing shelter for fish, sharks, turtles and rays, and snorkellers at high tide see schools of fish, reef sharks and rays around it. At low tide the wreck can be approached on foot across the reef flat, and it is one of the most photographed sights on the island. It is not a scuba dive but an easy snorkel and a remarkable piece of history for anyone staying on Heron.

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.
- Other water users
- Ask about vessel activity, exclusion areas and the agreed surface arrangements.
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.
