    The secrets of Sydney Harbour revealed

    Shifting sands, sunken ships and submerged cars. Port Authority’s hydrographic survey team reveal some of the stranger secrets resting on Sydney Harbour’s seafloor.

    The major shipping channels and berths of Sydney Harbour mapped out by the Port Authority hydrographic survey team — images like this help develop marine pilot plans to navigate large ships safely into the harbour.

     

    Underwater flyby
    An underwater bathymetric ‘flyby’ created by the hydrographic survey team at Port Authority of NSW reveals what lies beneath the water of Sydney Harbour. Note the wreck of the TSS Currajong lying just off Bradley’s Head.

    The Port Authority of New South Wales hydrographic survey team ensure the waters of Sydney Harbour, Port Botany, Port Kembla, Yamba and Eden are safe for shipping at all times. They measure and map the depths and features of the seabed so ships of all sizes can navigate safely through port.

    The survey team are part of Port Authority’s marine operations team that works 24/7 to keep the ports of NSW safe, secure and open to the world.
