Prior to winter each year the City undertakes planned beach renourishment along Quinns Beach, Quinns Rocks. Beach nourishment involves the placement of sand, sourced from a local sand quarry, along the beach. The additional sand creates a buffer against the impacts of winter storm events and limits the damage to coastal assets. The locations for beach renourishment are selected each year based upon the level of erosion experienced at each site prior to winter. Renourishment is generally undertaken at the following Quinns Beach sites each year which experience significant seasonal coastal erosion:
- Quinns Beach, north of groyne 1;
- Quinns Dog Beach, north of groyne 3; and
- Quinns Dog Beach, north of groyne 4.
Renourishment locations are not limited to Quinns Beach however, with renourishment often undertaken at Yanchep Lagoon and other locations along the City’s coastline when necessary.
Planned beach renourishment undertaken at Quinns Beach, north of Groyne 1, in April 2021.
Major erosion events that are caused by winter storms can sometimes result in unsafe beach access and beach use. To improve beach usability and make the beach safe, the City will also undertake reactive beach renourishment when necessary.
May 2023 Planned Renourishment
In May 2023 planned beach renourishment was undertaken at two locations along Quinns Beach. 5,000 tonnes was placed at Quinns Beach, adjacent to Frederick Stubbs Carpark and an additional 4,000 tonnes was placed at Quinns Dog Beach, north of Groyne 3. These works are supported by and were partly funded by the State Government under the Department of Transport’s Coastal Adaptation and Protection Grant Program

September 2022 Reactive Renourishment
In September 2022, beach renourishment works were undertaken at Yanchep Lagoon to improve beach usability, pedestrian access and surf club vehicle access prior to the summer season. These works included the placement of approximately 2,000 tonnes on the upper beach at Yanchep Lagoon and was required due to significant coastal erosion from storm events during the 2022 winter season. These works are supported by and were partly funded by the State Government under the Department of Transport’s Coastal Adaptation and Protection Grant Program.
