Port Adelaide completes Berth 25 extension as dredging continues

Construction work on the extension of Berth 25 at Port Adelaide’s Inner Harbor in South Australia has been completed, with the existing berth lengthened by approximately 74 metres.

According to Notice to Mariners No. 93 of 2026, issued by South Australia’s Department for Infrastructure and Transport, the project included the installation of a new sheet pile wall along the waterfront. The completed works have changed the berth’s alignment, with revised corner coordinates now published for navigational purposes.

The notice, published on November 9, confirms the completion of the structural extension but indicates that dredging operations remain underway. A new berth box depth will be published once those works have been completed, meaning the final updated depth has not yet been formally announced.

Mariners navigating near Berth 25 have been advised to exercise caution and account for the revised berth alignment while dredging continues. The changes affect Australian nautical charts AUS130 and AUS781, several electronic navigational charts and Australian Pilot Volume 1.

The completion of the extension represents a physical expansion of the Inner Harbor’s waterfront infrastructure. However, the notice does not specify any revised vessel size limits, additional cargo-handling capacity or timetable for the completion of dredging.

Further navigational information is expected once the remaining seabed works are finished and the updated berth depth is formally published.
