City of Onkaparinga will begin repair works on the storm-damaged Port Noarlunga Jetty early this week, with the aim of reopening it to the public as soon as possible.

The jetty sustained significant damage during recent storm events, prompting an immediate closure to ensure public safety.

The council says an engineering assessment has since confirmed the need to replace several structural elements, including girders, cross beams, decking and kickboards.

To minimise delays, it fast-tracked procurement of the necessary hardwood materials, which have a lead time of approximately four weeks.

It also engaged a specialist marine contractor to confirm availability and work through construction methodology, given the risks associated with marine infrastructure repairs.

The council is aiming for completion of priority works by the end of August, weather permitting.

Built in 1921, the Port Noarlunga jetty is a state government asset leased to the council.

Under the lease agreement, the Department of Infrastructure and Transport covers the cost of major storm repairs, with the council contributing the first $18,000.

Additional repairs identified in the engineering report will be scoped as part of the council’s 2025–26 Project and Capital Works program.

These include repair of several jetty pylons – a project already in early planning stages before the recent storms.

The council says this future work is currently being designed for delivery in early 2026, outside the peak summer period, to minimise disruption.
