17 March 2023: NSW Water has reported algae blooms at some swimming sites in the Shellharbour region, which may appear as a brown slick or sawdust like particles at the water surface. As a precaution, direct contact with the algae should be avoided as it can cause skin and eye irritations. It is expected the algae blooms will dissipate with changes in tide and wind conditions.

For information on beach closures please contact relevant authorities such as local councils.
