Work is underway on an important project to help restore the natural sand dunes of Great Mackerel Beach.

The dunes are susceptible to coastal erosion, particularly when Great Mackerel Beach is exposed to swells.

During the month-long project, teams will relocate sand to enhance dunes and install matting and native coastal plants to help stabilise the natural dunes.

Mayor Sue Heins said it’s part of a longer-term project to protect the dunes.

“Great Mackerel Beach is much-loved by Northern Beaches residents and visitors alike, as an ideal location for swimming, fishing and family picnics,” she said.

“This important work will nourish the natural sand dunes, build the natural resilience of the public beach and ensure the community can continue to enjoy this beautiful location.”

“In recent months, Council teams have worked closely with residents to identify and remove boats from the sand dunes as a way of further protecting the area.

“We encourage residents and visitors to Great Mackerel Beach to stay out of the dunes and avoid leaving boats and other vessels on the sand dunes.”  

The work will be completed in 2 sections, starting in the area north of the public wharf and then continuing south of the wharf on Council reserves. 

Over the next month, a selection of 18 species of native coastal plants, such as warrigal greens, beach spinifex and beach fan-flower will be planted in the dunes on the Council reserve.

The work on the sand dunes will typically take place between 7am and 6pm weekdays and may also occur on Saturdays between 8am-1pm. 
Beach and dune access will be temporarily restricted while the project is underway.

Where possible, Council will minimise the impact of the temporary construction work.
