Meet the site
The Moltke is Magnetic Island's best-known and most frequently dived wreck, and a staple training dive for Townsville and island dive schools. The iron three-masted barque was built in Hamburg in 1870, around 50 m long, and arrived in Townsville in 1890. After years as a working vessel and later a hulk she was scuttled in Geoffrey Bay early in the twentieth century (sources give 1911 or 1913) to act as a breakwater for the island's ferry landing – but she was reputedly placed in the wrong spot to be much use. During the Second World War she was used for target practice. Despite that treatment, the hull is still fairly intact and totally covered in hard and soft coral. It lies in 5–8 m (depending on tide), about 100 m offshore from the old vehicle-ferry landing, with a mooring buoy on the bow and a wooden pylon at the stern. Around it stand coral heads and bommies, plus a research 'experiment platform' with metal arms and a large cylinder that the North Queensland Underwater Explorers Club uses as a start point. The wreck works as a fish aggregation. Schools of sweetlips, batfish and yellowtail fusiliers hang over it, with Moses perch, juvenile coral trout, drummer, rabbitfish, flowery cod and tuskfish; painted crayfish hide in the plates, nudibranchs crawl over the hull, and blue-spotted lagoon rays and epaulette sharks lie on the sand. Wobbegongs, lionfish, moray eels and turtles are regular, and baby blacktip reef sharks patrol from the nearby mangroves. At night it is excellent, with crayfish and sleeping fish. The site is in a Marine National Park green zone. Visibility is often poor and the wreck is easy to lose, so slow approaches, careful navigation and a guide on the first visit pay off. It suits new divers, snorkellers in good visibility and anyone after an easy, fishy night dive.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
SS Moltke Wreck (Geoffrey Bay) is recorded as Wreck in Townsville & Magnetic Island. The listed access is shore or boat. 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.
- Other water users
- Ask about vessel activity, exclusion areas and the agreed surface arrangements.
- Lines and obstructions
- Discuss any known entanglement concerns and the suitability of the planned area.
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.
