Coastal Monitoring
The City monitors the seasonal and long-term changes along our coastline, to better understand how we can manage and protect our coastal environment for the future.
How do we monitor?
- Photographs captured twice a year at 51 beach sites.
- Five beach monitoring cameras, capturing a photo every hour.
- Land surveys of the City's coastline in April and October each year.
- Aerial imagery of the coastline.
- Wave date captured from three wave buoys moored off the City's coastline. This can be viewed by visiting: wawaves.org/wanneroo.
- Water level and wind data supplied by the Department of Transport and the Bureau of Meteorology.
What did we find?
Between April 2023 and April 2024 there was an increase in beach volume along the Mindarie and Two Rocks coastlines however there was an overall decrease in beach volume along the Quinns Rocks and Yanchep coastlines.
How do we help?
In September 2022 we placed sand at Yanchep Lagoon Beach in response to major erosion caused by winter storms. Beach renourishment was undertaken to improve beach usability and pedestrian access ready for the summer.
Our Beach Renourishment Program ensures safer and improved beach access, while also protecting the dunes and coastal environment.
In April 2023 we undertook beach renourishment at two locations along Quinns Beach which created a buffer against winter storms.
How can you help?
- Stay off the dunes.
- No 4WDing on the beach.
- Report any major erosion or beach safety issues to us - wanneroo.wa.gov.au/contactus.
Coastal Monitoring Report
Every six months a Coastal Monitoring Report is produced that outlines the methodology of the program and details any coastal changes that were observed over the last 12 months.
