An example of the erosion of the beach at Victor Harbor.
There is constant coming and going of coastlines as quite natural and that this has been going on for decades. It continues today. However, another discernible pattern is being overlaid on this cycle—it is noticeable that the sea is slowly eating into the sand dunes. Some of the low lying coastline where there are holiday houses are vulnerable, and some local councils are starting to take measures to defend, retreat, or block development.
