Faecal pollution likely at dozens of Sydney beaches

Some of Sydney's most popular beaches and bays could contain faecal pollution today with poor water quality likely in several areas.

Beaches in Cronulla, Botany and some in north Sydney have pollution warnings, with the beaches potentially susceptible to human faecal matter.

A number of beaches and bays along the coast have also been issued the same warning, including but not limited to, the Carrs Park Baths, Frenchmans Bay, Gunnamatta Bay Baths, Gymea Bay, Malabar Beach, Monterey Baths and at least a dozen more.

"Caution advised for swimming. Water quality usually suitable for swimming, but young children, elderly or those with compromised health may be at increased risk," the NSW Government Beachwater website says."

Bronte and Coogee beaches have been declared safe today after testing yesterday revealed possible faecal pollution in the water.

The NSW Beachwater website provides live updates on the water quality across Sydney.

"Our beaches almost always have high water quality – but after rain the quality can be impacted," NSW Environment Minister Penny Sharpe said.

"The BOM is predicting a wet summer, so check before you swim as the weather warms up."
