NSW has recorded no new locally acquired coronavirus cases over a designated 24-hour period for the first time in almost three weeks.
In the 24 hours to 8pm Sunday, the state recorded only seven new cases in returned overseas travellers in hotel quarantine.
But two new local cases were recorded after that 24-hour period ended.
The cases are connected to the Berala BWS case, Acting Premier John Barilaro said on Monday.
Despite the better news, Mr Barilaro said testing numbers were still "far too low" and implored residents in western Sydney to attend clinics if they have the slightest of symptoms, even if they have been tested previously.
Some 22,275 people were tested in the 24-hour period ended Snday night, up slightly from 18,923 the previous day.
