Woodman Point Ammo Jetty Dive Closure Continues Through Major Replacement Project

The dive exclusion around Woodman Point Ammo Jetty will continue through a major replacement project scheduled to begin on site in early November 2026.

Transport WA’s October 15 update says the jetty and the waters immediately beside and beneath it will remain unavailable for scuba diving, freediving, snorkeling and swimming until the project is complete. Parts of John Graham Reserve, including the small southern car park, nearby grassed area and the direct pathway to the jetty, are expected to stay closed until late 2027.

The jetty was already closed after storm damage during the WA Day long weekend in June. The new announcement is therefore not a reopening followed by a fresh closure. It supplies the construction timetable and makes clear that divers should expect a long interruption while the deteriorated structure is demolished and replaced.

The restriction is limited to the construction area. Transport WA lists Sue’s Groyne, Woodman Point Groyne and the Omeo Wreck as possible alternative diving, freediving and snorkeling locations when conditions permit. A temporary beach access point will be installed north of the jetty, but that access does not authorize entry into the closed water beneath or immediately beside the work site.

The project retains the original piles installed in 1939 because of their heritage value and established marine growth. The replacement jetty is designed with a wider deck, a dedicated diver and swimmer ramp, low-level platforms, emergency ladders and more separation between divers and fishing lines. Transport WA expects approximately 12 months of construction, while associated reserve closures may continue into late 2027.

After the new jetty opens, the water immediately around it will continue to be closed to motorized vessels. That permanent separation is intended to protect people using the area for diving and snorkeling; kayaks and small unpowered dinghies may still land at the completed jetty.

Divers should not rely on older shore-entry directions or attempt to approach the original piles from the beach, boat or another section of the reserve during construction. Work barges, demolition activity, temporary barriers and altered pedestrian routes can expand the practical hazard beyond the familiar entry point. Clubs and instructors should move planned training to an authorized alternative and confirm parking and access before arrival.

Transport WA has not published a precise completion or reopening date. “Late 2027” applies to parts of the reserve, while the in-water exclusion lasts until completion of the jetty project. A reopening should therefore be reported only after a new official notice confirms that the construction-water restriction has been lifted.
