Beachgoers should bypass The Boneyard until further notice after Kiama Council issued a warning on Wedneday to avoid the popular swimming and surfing spot due to a suspected marine algal bloom that has washed ashore.

Algal blooms, also known as cyanobacteria, can cause skin irritations and they usually dissipate quickly with changes in wind and tides.

Council has advised that people should avoid swimming or any water-based activities in the area that could bring them into direct contact with the bloom.

The algal bloom at The Boneyard is unlikely to be connected to dead fish found at the area, according to Council, as Fisheries NSW is investigating similar fish deaths along the South Coast.
