Works are underway on a $1.5 million project to upgrade the groyne at Point Peron.
The spur groyne, originally built in the 1970s, is being refurbished and extended by 20 metres using around 10,000 tonnes of rock from the existing structure and an extra 5,000 tonnes of rock trucked to site.
The extended groyne will trap a greater amount of sand and ease erosion on surrounding beaches.
The adjoining boat ramp will also benefit from greater protection from waves and a reduction in sand entering the facility, limiting the need to dredge each year.
"We have some beautiful beaches in Rockingham, enjoyed by both swimmers and boaties," Rockingham MLA and Premier Mark McGowan said.
"This project will make a big difference by providing improved year-round boat launching conditions for skippers."
Identified as a high priority coastal erosion project as part of the State Government's $5.5 billion WA Recovery Plan, the City of Rockingham received $650,000 to undertake the work.
The City of Rockingham has awarded Perth-based company WA Limestone the contract for the project, which will create seven full-time and a further four part-time positions.
Works are due for completion by the end of May.
