Sydney's Northern Beaches COVID-19 cluster grows to 17.
The Northern Beaches cluster of COVID-19 has ballooned to 17, with 12 new cases identified on Thursday.
Northern Beaches residents have been told they should work from home and stay home as much as possible for the next three days.
They should avoid aged care facilities and hospitals and other high-risk venues like gyms and places of worship, and avoid leaving the Northern Beaches area.
More cases are likely to be identified, NSW Health warns.
It is absolutely vital that everyone immediately comes forward for testing if they have even the slightest of COVID-19 symptoms, and self-isolates.— NSW Health (@NSWHealth) December 17, 2020
There are more than 300 COVID-19 testing locations across NSW, many of which are open seven days a week.
The source of the cluster remains a mystery, but authorities are investigating a potential super-spreader event at a Northern Beaches RSL.
The cluster has led WA premier Mark McGowan to order any arrivals in his state who were in NSW from December 11 to self-isolate until they test negative.
Tasmania elected on Thursday to ban anyone who had visited the venues on NSW's health alert list from entering the island state. Those in NSW who are set to travel to Tasmania must also reapply for their e-Travel pass.
