Coastal Adaptation Projects Currently Underway

Sunset Beach Geotextile Sand Container Groynes

Construction of three additional Geotextile Sand Container (GSC) groynes and sand nourishment along Sunset Beach to mitigate coastal erosion will begin in early January 2024.

Three additional 40m long low-crest GSC groynes, spaced 70m apart, will be constructed south of the recently completed groynes located south of Triton Place.

Approximately 7,000m3 of sand will also be imported to nourish the foreshore area. The sand will provide an initial nourishment to the foreshore south of the groyne and allow the littoral drift process to feed the beach to the north of the northern groyne.  Littoral drift is the process by which sand is moved along the coastline by wave action. For Western Australia, this process moves sand along the coast in a northly direction.

The $1.365 million project is joint funded with $615,000 provided by the State Government through the CoastWA Hotspot Coastal Adaptation and Protection (H-CAP) Major Project Fund.

Construction of the groynes will be undertaken by a local contractor with coastal engineers M P Rogers providing technical services.

The estimated date of completion is April 2024.
