Transport and Main Roads – Rosslyn Bay Dredging

Keppel Bay

Rosslyn Bay is situated just east of Rockhampton adjacent to Yeppoon in Northern Queensland. The central feature of the town is its busy harbour, used by both commercial and recreational vessels.

The works involved maintenance dredging to the Boat Harbour to improve navigational access comprising a total dredge volume of just over 85,000m3. The materials were a combination of silt and sand and, as some areas had not been dredged for over 20 years, consolidated material which was subsequently harder.  Dredged materials were transported by underwater pipeline to an offshore disposal area 1.1km North East of the harbour entrance.  The works were carried out by Birdon’s Cutter Suction Dredge “Darwin”.
