Mariners should continue to maintain a proper lookout and navigate with caution in this area until the bridge works are complete.

Mariners are advised a vessel is currently semi submerged on its mooring within the Mosman Bay mooring zone, Swan River.

Mariners are advised to exercise caution when transitioning this area and be aware for potential floating debris.

Mariners are advised that JoJo's jetty in Nedlands has collapsed. 

Please navigate with caution and keep a wide berth of the jetty.

Mariners are advised that the jetty protruding from the Dome Cafe in East Fremantle has collapsed and is partly lying below the water level. 

Mariners are advised to navigate with caution, and keep a wide berth of the jetty, there could be possible debris in the water.

Mariners are advised that due to scaffold installations on the Fremantle Rail Bridge, the clearance height of navigable spans upstream and downstream reduced from 7.4m to 6.9m at Highest Astronomical Tide.

All other Fremantle Rail Bridge spans have a reduced clearance height of 6.75m at High Astronomical Tide.

This restriction will be in effect from Friday, 28 November 2025, to Friday, 5 December 2026.

Mariners should maintain a proper lookout at all times and proceed with caution when navigating under the bridge.

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.
