Several beaches in Sydney have been closed by officials as red algae turned the water a deep red.
The unusual phenomenon can happen when certain weather conditions result in a more widespread bloom of algae than is usually seen in the region. Due to concerns over the risk to swimmers, authorities took the decision to close the beaches and conduct tests on the water.
"There are some possible risks to human health from red algae including skin rashes and eye irritation, and for this reason the beach will remain closed until the algae dissipates," said a spokesman. "Signage has been installed at Clovelly Beach, and council lifeguards are advising people not to swim."
"Patches of the red algae, a natural phenomenon that can be exacerbated by certain weather conditions, were sighted between Bondi Beach and Maroubra Beach this morning."
