Welcome to HDSA

The underwater, by the water, for the water experts

HDSA Group (Hope Diving Services Australia Pty Ltd) are at the forefront of the Marine Construction and Commercial Diving Industry.

A Sydney owned and operated Underwater Construction company, HDSA Group work Australia wide. We specialise in the inspection, maintenance and construction of marine structures including wharves, jetties, sea walls and pontoons. This often also involves creating Annual Maintenance Plans for all assets on the wharves and project managing new construction projects.

HDSA is now one of the largest On-Shore Commercial Diving Companies that operates out of the East Coast of Australia. Much of this is attributed to hard work and the innovative approach HDSA Group take when planning or reviewing construction. Time after time, HDSA Group brings a unique and innovative perspective to projects based on experience and knowledge. The result is often savings in time and money.

HDSA has multiple teams comprised of Commercial Divers, Heavy Equipment operators, Labourers and Bridge & Wharf Carpenters. All of HDSA's staff are highly trained in all aspects of Marine Construction and are constantly striving to stay at the top of their respective fields, with up to date skills and practical industry knowledge.

HDSA operates using a wide range of its own equipment including two 5 tonne Crawler Cranes, a Barge with a full Dive Setup and 3 tonne Hiab Crane and Hydraulics.
