Advice: Dredging Works - Point Peron Boat Harbour - 'Swan V'
Mariners are advised that maintenance dredging works at Point Peron Boat Harbour will commence early-May 2023 and will proceed until approximately late-July 2023.
Dredging will mainly occur Monday to Friday between the hours of 0600 and 1800hrs, with provision to take place over the weekends, if required.
There will be staggered, partial closures of boat ramps and pontoons within the boat harbour throughout these works. Closed boat ramps will be marked by a yellow buoy equipped with a flashing yellow light at the end of the ramp.
The works are being carried out by the 20m cutter suction dredge 'Swan V', equipped with 400m of floating & submerged pipeline. The floating pipeline will be marked with yellow buoys, equipped with flashing yellow lights. The dredge has no self-propulsion and uses anchors and spuds to move. Dredged material will be pumped onshore on the north-western side of the boat harbour, with the pipeline laid over the inner harbour rockwall, inside the northern breakwater. Mariners are recommended to keep well clear of this disposal point.
Pipeline disposal point location: 32: 16.211S, 115: 41.865E
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 & 72.
Chart reference: WA913 – Cape Peron to Dawesville
Mariners are advised to use caution when transiting the area and keep well clear of the above operations. Alternative boat launching facilities are located at Bent St, Palm Beach (East and West) and Port Kennedy boat ramp facilities, located along Rockingham’s coastline.

LIDAR buoy location 2: 31° 52.594'S, 115° 43.121'E
LIDAR buoy location 3: 31° 52.532'S, 115° 43.318E
LIDAR buoys are circular buoys with side mounted solar panels and wind generators extended on top. They are yellow and black in colour, approximately 4.5m in diameter and 4m in height, and equipped with flashing yellow light.
Flash rate: Q(5) Y 20s
LIDAR buoys will be deployed periodically at the above locations until around 31 December 2023.
No vessel is to moor to or interfere with the above buoys at any time.
Mariners are advised to navigate with caution when transiting the area and keep well clear of the above buoys.

Advice: Breakwater construction and reclamation works, Ocean Reef Marina
Mariners are advised that works to construct two new breakwater groynes at Ocean Reef Marina commenced in mid-April 2021 and are expected to be completed around June 2023. Three lit lateral groyne beacons (1 starboard, 2 Port) have been permanently installed to mark the entrance into the Marina.
Access to the marina’s boat ramp and jetties will be maintained at all times.
Works on the reclamation areas commenced in September 2022 and is expected to be completed around June 2023.
Works will take place Monday to Saturday, between 7am to 6pm as required, using land based heavy machinery, including long reach excavators (approximately 30m reach), front end loaders, dump trucks and dozers.
Construction works for the reclamation areas will be within a silt curtain located in an alignment from the northern end of the boat ramp to the head of the northern breakwater. The silt curtain will be marked by red flashing lights spaced at approximately 100m intervals.
Land based operators will monitor Marine Radio VHF Channel 16 during operating hours.
Pursuant to section 66 of the Western Australian Marine Act 1982, I vary the previous notice relating to the closure of waters published on the Departments Temporary Notice to Mariners website on 26 March 2021 and close the waters to all vessels within 20m of construction works occurring on the Ocean Reef Marina Southern breakwater.
In addition, mariners are advised to use caution when transiting the area and keep well clear of the above operations at all times and note;
All waters of the Ocean Reef Marina are closed to windsurfing, Kitesurfing and winging activities
All waters within the silt curtain are closed to all vessels other than vessels associated with construction of the marina and swimming is prohibited.
This notice is valid from 12/09/2022.
