Erosion on Adelaide Northern beaches

The breakwater at Semaphore South was built to collect sand to mitigate the erosion at Semaphore Park.

However in recent years the sand collected at this breakwater has been entirely redirected to West Beach, leaving Semaphore Park more vulnerable to the increasing frequency of storms. With the added impact of sea level rise this combination of factors has led to severe erosion along the beach at Semaphore Park and neighbouring Tennyson Dunes.
This is impacting houses and the planned future coastal path.
