About us

The Port Authority of New South Wales Survey Services team ensures the waters of Sydney Harbour, Port Botany, Yamba and Eden are safe for shipping at all times.

Depths of channels and berths can change over time and hazards, like a 12 metre long pole found stuck upright in the Harbour bottom to cars dumped from shore, can appear anywhere without warning.

Survey Services regularly completes hydrographic and bathymetric surveys of Sydney Harbour, Botany Bay, Yamba and Eden to search for hazards and monitor changes to berth and channel depths.
