Excavators were used to place rock for Western Australia’s new Bunbury breakwater
WA Limestone Contracting and Italia Stone Group have completed rock work on the new 460-metre northern breakwater at Bunbury’s Casuarina Boat Harbour in Western Australia.
Completion of the breakwater rock structure followed the dredging of its seabed footprint in late 2024 and the relocation of more than 120,000 cubic metres of material.
It took almost a year to place 290,000 tonnes of core rock and 65,000 tonnes of armour sourced from quarries at Roelands, Byford, Shenton Ridge, and Jarrahdale to build the breakwater.
The $69.2 million joint-venture breakwater contract which also includes works to upgrade the Koombana groyne, is the centrepiece of Stage 3 of the Transforming Bunbury’s Waterfront project.
It is focused on rejuvenating the harbour by creating a regional hub for the marine industry and delivering quality infrastructure for the local community.
With the breakwater now in place, work will start in 2026 on the roads and services that will be required to improve public access to the breakwater and support further development of the area.
It will also make way for the delivery of a new $4 million universally accessible fishing platform on the breakwater’s northern side.
“Bunbury has long had an outstanding waterfront, and this project builds on that strength to enhance community use and create new opportunities,” acting WA South West minister Reece Whitby says.
“With key structures now in place, Bunbury is ready to unlock the next phase of development.”
