Warning for backpackers in Sydney's Bondi Beach

An additional 97 cases of COVID-19 have been diagnosed in NSW, bringing the total number of confirmed cases in NSW to 533.

Of the new NSW cases, several are in backpackers staying in the Bondi area. NSW Health says there were two recent parties that some of the cases attended where they may have acquired their infections.

"People who also attended these parties should be on alert for symptoms of COVID-19 and immediately isolate themselves if any symptoms develop," NSW Health said in a statement.

"They should then seek testing via a GP or COVID clinic, and tell the medical service that they had attended one of the parties."

The parties are:

·         Boogie Wonderland party at the Bucket List on March 15 between 4pm - 11pm

·         Club 77, Darlinghurst from midnight on March 15 to 4am March 16

The warning comes after Bondi Beach was cleared after social distancing guidelines were ignored by hundreds of beachgoers.
