Hallett Cove Beach is an exposed beach mostly used for walking, fishing and diving, with the closest built infrastructure approximately 80m behind the foredune. The beach is periodically eroded during storm tides, around the mouth of the Field River and along constructed embankments of Heron Way Reserve. City of Marion uses soft approaches to stabilise the dunes to prevent further erosion. Revegetation, access restriction and sand drift fencing have all been used successfully, with only minor erosion of the dunes seen after storm tide events in 2020-2021. City of Marion delivers an annual coastal monitoring program that assess impacts of annual storm tides and changing sea levels, wind and wave conditions. This includes specialist data capture along with a community citizen science CoastSnap photomonitoring program. The project is funded equally by the local and state governments.
