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

Mariners are advised that construction works for the Fremantle Traffic Bridge Project will impact navigation under the bridge from October 2025 to November 2026.

The project involves the construction of the new traffic bridge and the removal of the existing Fremantle Traffic Bridge. During this period, large concrete segments and associated materials will be lifted over each navigation channel, at times, using cranes, resulting in intermittent interruptions to river traffic.

Impacts on navigation:
•    Intermittent closures of one navigation channel (north or south) will occur during lifting operations.
•    Closure durations may range from 15 minutes to over two hours depending on specific lifting requirements.
•    Contraflow vessel management will be in place during these intermittent closures.

Work vessels and safety measures:
•    Spotter vessels will assist in managing vessel traffic and alerting approaching river users.
•    Spotter vessels will be stationed at strategic points and will communicate through Marine VHF Channel 71 (and monitor VHF Channel 16).
•    All vessels involved will display lights and shapes as required by the Prevention of Collisions in State Waters Regulations 1983.
•    Signage will be displayed at local boat ramps along the river and at coastal locations to inform all river users of the potential navigation impacts.

Mariners are advised to maintain a proper lookout at all times, navigate at a slow speed to reduce wake and wash, and adhere to any instructions issued by signage and spotter vessels.

Warning - Leeuwin Cadet Jetty - Swan River East Fremantle

Description: Mariners are advised that the current condition of the Leeuwin Cadet Jetty is condemned and not safe to moor alongside.

Location: 32° 1.565'S, 115° 46.100'E Chart reference: Department of Transport chart WA898 - Swan and Canning Rivers

Non buoyant long lines of up to 200m will be deployed parallel to the river bank for approximately two hours at a time. Where possible, the lines will be deployed outside of navigational channels and to the outer limits or the river however sharks and river conditions could mean the equipment is dragged on to channels. The end of the lines will be fitted with a vertical riser with a white float and reflective tape at the water surface. During the deployment, the equipment will be monitored by vessel at all times.

Mariners and divers are reminded to exercise caution and not interfere with fishing equipment.

A submerged hazard has been reported close to the shore, approx. 30m west of the Coode Street Boat Ramp.

Perth Water, Swan River
Mariners are advised of daylight sea plane operations, including landing and take-off activities, in Perth Water.

Chart reference: DoT Chart WA - 898'Swan and Canning River'. Mariners are advised to navigate with caution when transiting the above area and be aware of sea plane activity in this location.

Swan River, Fremantle traffic bridge
Mariners are advised that large vessels may at times navigate downstream through the southern span of the Fremantle Traffic Bridge against the flow of traffic. This may occur whilst access through the Central and Northern navigable spans are restricted due to tidal influences or closures due to ongoing works.

Mariners are advised to keep a safe speed and lookout, and navigate with caution when transiting upstream through the southern span of the Fremantle Traffic Bridge.
