Mariners are advised that maintenance dredging works at Jurien Bay Boat Harbour will commence Mid-November 2025 and will proceed until approximately Mid-April 2026.

Dredging operations will occur Monday to Saturday between the hours of 0700 and 1900hrs and on Sundays and public holidays between 0900 and 1900 hours.

The works are being carried out by the cutter suction dredge “Kingston”, equipped with 1.2km of floating & submerged pipeline marked with yellow buoys, displaying rhythmic flashing lights. The dredge has no self-propulsion and uses anchors and spuds to move. Dredged material will be disposed offshore and the pipeline will terminate at a yellow pontoon, marked with yellow flashing light. Mariners are recommended to keep clear of the disposal point.

The dredge and connected pipeline will remain unmanned in the area of operation after normal operating hours for the duration of the works.

The dredge will exhibit shapes and lights in accordance with the Prevention of collisions at Sea Regulations 1983.

If mariners are unsure of where to safely pass the dredge vessel, they are requested to contact the operators who will be monitoring the following radio frequencies:

VHF Channel 16 & 74

Mariners are advised to use caution when transiting the area and keep well clear of the above operations.

Mariners are advised that deployment operations will take place on the 28th of October 2025. 

The objects being deployed will consist of a 1m3 subsea component coupled with a yellow surface buoy with flashing light (FL Y 2s). the objects will lie 4.5m below the surface at LAT. 

Operations will be undertaken from a research vessel ‘Pelagic’ equipped with a davit and slip line used to lower objects to the seafloor.  

All vessels taking part in these works will display lights and shapes in accordance with the Prevention of Collisions in State Waters Regulations 1983 at all times.

Operators will monitor Marine VHF Channel 16.

Mariners are advised to maintain a proper lookout at all times and proceed with caution when navigating in this area.

Mariners are advised that there will be 5x various metocean data collection objects deployed around Lancelin on the 2nd of October 2026, with a retrieval date of October 2026. The shallowest object will lie 3.5m below the surface at LAT. 

Operations will be undertaken from a research vessel and objects will be positioned by divers.

The international code flag “A” will be exhibited whilst diving operations are in progress.

All vessels taking part in these works will display lights and shapes in accordance with the Prevention of Collisions in State Waters Regulations 1983 at all times.

Objects will be positioned at the following locations:
(-31;0.7913 S, 115;18.5696 E)
(-31;0.5898 S, 115;19.4139 E)

The above DWR’s are yellow in colour, approx. 0.42m in diameter and equipped with flashing yellow light attached to a small orange float about 10m apart attached to bottom anchor.

Flash rate: Fl Y (2.5s)

No vessel is to moor to, or interfere with, the above DWR’s.

Mariners are advised to navigate with caution when transiting the area and keep well clear of the above DWR’s.

A directional wave buoy (DWRB) has been deployed approximately 7 nautical miles west of Jurien Bay, at the location below. The DWRB is yellow in colour, approximately 700mm in diameter, and equipped with a 2m whip antenna and flashing yellow light.

Flash rate: Fl (5) Y 20s

Mariners are requested to maintain a minimum distance of 100 meters from the DWRB, including any associated fishing equipment at all times so as to not interfere with or damage the DWRB.
