NSW has reported three new cases of Covid-19 community transmission, all linked to western Sydney, while mystery sources have now been tied to the northern beaches cluster.
Two cases – a man in his 40s and a man in his 20s – are under investigation after 32,000 people came forward for testing in the 24 hours to 8pm on Thursday.
The third case, a man in his 20s, is a close household contact of one of the other two men.
None of the three new cases are linked to the northern beaches hotspot which now totals 146 after two previously recorded infections were linked.
The state government is urging western Sydney residents from Greystanes, Auburn, Berala and Lidcombe with even the mildest of symptoms to get tested.
Patrons who dined at the Swallowed Anchor restaurant in Wollongong on December 19 have been urgently called after one case from Croydon and another from the local area both attended on that date.
"There may have been a transmission event at that venue," NSW Chief Health Officer Kerry Chant said.
Several other venues have been added to the Covid alert list after an update from NSW Health at 1pm on Friday.

‘Covid still hasn't gone away’
Prime Minister Scott Morrison said the recent low numbers recorded in NSW were encouraging and thanked the community for listening to health advice and coming forward for testing.
"Covid still hasn't gone away, it hasn't taken a holiday, it won't be going anywhere, and as a result, we continue to deal with the very serious challenges," Mr Morrison said.
Meanwhile, the mystery source that sparked the Croydon cluster and two cases in Wollongong has now been linked to the Avalon cluster, with the connection between the cases revealed by genetic testing.
At the southern NSW border, Victorians are facing lengthy queues to cross into their home state after it imposed travel restrictions from midnight on Friday, with anyone arriving after that time having to spend a fortnight in quarantine.
Premier Gladys Berejiklian said the border closure was not the best use of resources.
"I think we're better off asking the community to come forward to get tested, cutting off those chains of transmission, making sure everybody has enough information about venues and about COVID safe activities," Ms Berejiklian said.
