Around 100,000 cubic metres of seagrass has been removed from Port Geographe and the beach is now ready for summer.

The City of Busselton and the Department of Transport worked together to remove the seagrass along the 1.5 kilometre stretch of coastline since July 2021.

From late July earthmoving equipment was used to breakdown compact accumulations of wrack and push it to the water line prior to westerly winds and storms encouraging dispersal by waves and currents and assisting the natural flow.

Transport minister Rita Saffioti said the success on Western Beach follows the pumping of 20,000 cubic metres of sand from an offshore disposal area back in March 2021.

The pumping of sand allowed nearby Wonnerup to replenish the beach before erosion events during winter.

"These outstanding results reinforce the value of the nine-month technical investigation that was undertaken last year and demonstrate the commitment to providing a useable beach at Port Geographe east and west of the breakwater," Ms Saffioti said.

"In less than a year there has been a significant change and the early results are encouraging."

Both measures were key recommendations of the Port Geographe Technical Working Group, formed to assess the performance of the reconfigured coastline and improve performance.


The department will continue to work closely with the City and the community to manage the coastline at Port Geographe and Wonnerup delivering benefits for property owners and users.

South West MLC Jackie Jarvis said the seawrack at Port Geographe was well known and would virtually turn the beautiful beach unusable.

"Well done to the Department of Transport and the City of Busselton for working with the community on this important project," she said.
