NSW Water has reported algae blooms at some swimming sites, which may appear as a brown slick or saw-dust 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.
