- Sunk in 1916 (Steamship, 62 tons); protected as underwater cultural heritage, so look but do not touch.

About Dunster Castle Wreck (Stokes Inlet)
The Dunster Castle was a small (62-ton) steamship lost in 1916 while delivering railway rail along the south coast. She was wrecked west of Shoal Cape near Stokes Inlet, about 80 km west of Esperance, and her remains lie roughly 90 m offshore.
Marine Life Network describes a 20 m section of hull showing above the sand, with iron frames, the top of the propeller, and the boiler and engine visible. It also warns that surf breaks continually over the site and that a strong 5-7 knot current running south-east makes it dangerous – a challenging, little-visited site suited only to experienced wreck enthusiasts.
The wreck is in Stokes National Park, a remote area of inlets, dunes and heath reached by 4WD tracks, with no dive services nearby. For most divers it is of historic interest only; the realistic diving options in the Esperance region are the Sanko Harvest, the Recherche Archipelago islands and the town's jetty and bays. Anyone attempting the Dunster Castle should do so only in rare flat conditions, with surface support and emergency planning appropriate to a remote site.

Getting there & entry
Remains of a 62-ton steamship wrecked in 1916 about 90 m offshore west of Shoal Cape near Stokes Inlet, west of Esperance, in a permanent surf zone with strong current.
From Esperance drive west on the South Coast Highway for about 80 km and turn south into Stokes National Park; 4WD tracks lead toward the coast west of Shoal Cape (check DBCA for current track status). The wreck lies about 90 m offshore. This is a remote site with no facilities or phone coverage in places – travel in company and carry recovery gear.
Entry: Beach/surf entry
Weather, swell & tides
Marine Life Network notes that surf breaks continually on the site and that a strong 5-7 knot current running south-east makes it dangerous. It can only be attempted in exceptionally rare flat conditions, typically a period of northerly winds with minimal swell. Even then, rips form along this open coast, the water can be turbid, and weather changes quickly with approaching fronts; the 4WD tracks into Stokes National Park may also be closed after rain.
Best season: Late summer to autumn (February-May) for the calmest seas and clearest water
How the dive is usually run
Only on an exceptionally flat day: enter through the surf with a buddy and surface cover, locate the hull section, boiler and engine, and exit before conditions change. Do not attempt if any surf or current is running.
Marine life
- Surf-zone fish (herring, salmon, whiting)
- weed-covered ironwork
