Meet the site
The Sanko Harvest is the largest shipwreck dive in Australia and is often described as the second-largest diveable wreck in the world. She was a 174 m, 32,500 DWT Japanese dry bulk carrier carrying 32,790 tonnes of phosphate fertiliser (plus about 680 t of heavy bunker fuel) when she struck a charted reef near Hood Island in the Recherche Archipelago on 14 February 1991. The subsequent inquiry blamed the master and second officer for failing to correct the ship's charts. Over the next few days the hull broke into pieces and sank, and all her fuel oil escaped; much of it washed onto the beaches of Cape Le Grand National Park, oiling seal colonies and seabirds before a clean-up in which about 80% of oiled seal pups were rescued. Salvage plans were abandoned.
The wreck now lies in about 40-44 m of water, with its highest points around 13 m. The ship split into large sections – the forward holds and the stern with its accommodation are the main pieces – and three decades of breakdown have opened the holds into a vast landscape of plates, frames and girders. Since 1995 a 500 m no-take zone has protected the site, and the steel is covered in anemones, seaweed, soft coral, sponges and ascidians. Fish life is heavy: blue groper, boarfish, bullseyes, morwong, sweep, perch, yellowtail and red snapper, with seals and dolphins sometimes appearing.
The scale is the point. A single dive covers only a small part of the wreck, and most recreational divers explore the upper hull between 13 and 30 m. The deeper parts, including the stern and bridge areas that reach the sand, are for deep-trained or technical divers.
It is a genuinely remote wreck dive – a long boat ride from a town 720 km from Perth – and weather cancels many planned trips, but for experienced divers it is one of the great temperate wreck dives in the southern hemisphere.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Sanko Harvest Wreck is recorded as Wreck in Esperance & Recherche Archipelago. 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.
- 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.
- Planned depth
- Confirm the intended route and training requirements; the recorded maximum is not a target.
- Overhead environments
- Ask whether the plan stays entirely in open water. A wreck or cave listing is not permission or training to enter.
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.
