Sutherland Dock, Maritime engineering structure on Cockatoo Island, Sydney, Australia
Sutherland Dock is a basin carved into sandstone on the southwestern side of Cockatoo Island, stretching about 210 meters in length with a water depth of roughly 10 meters. The structure features a sophisticated lock system that allowed ships to safely enter and exit the dock.
The dock was completed in 1893 and served during both World Wars as a major facility for the Royal Australian Navy to build and repair warships. It became central to the navy's operations when ships needed urgent maintenance or damage repair.
The dock shows how Australians built up their maritime industry, representing the growth of shipbuilding knowledge from the Victorian era onward.
To visit the dock, take the regular ferry to Cockatoo Island where it is open and easy to access. Wear sturdy shoes and bring water, as you will walk on historic stone surfaces and be exposed to the sun on open ground.
The dock kept its original steam-powered lock mechanism, but was converted to electrical operation in 1918, showing a rare blend of old and new technology. This conversion reflects the technological shifts that happened during World War I.
