New South Wales has recorded 35 new cases of coronavirus, with 24 in isolation.
Shoppers who visited a busy Woolworths where a staff member was unknowingly infected with Covid have been ordered to isolate.
The alert concerns Hillsdale Woolworths, 6km south-east of Sydney's CBD, with hundreds of shoppers now plunged into 14-day isolation, regardless of any Covid test results.
Woolworths confirmed to Daily Mail Australia that an infected staff member worked on June 30 between 9.30am and 6.30pm, as well as on July 1 between 9am and 6pm.
Anyone who attended the Maroubra Coles on Monday, June 28 from 7.10am to 8.20am and also on Tuesday June 29 11pm to 11:45pm, is also considered a close contact, but none of its workers are infected.
The stores were among a list of new venues announced by NSW Health late on Sunday night, after the state recorded 16 new Covid cases.
The long list of venues and public transport routes flagged by NSW Health is spread right across the Harbour City from the Covid-ravaged eastern suburbs, to the inner west, outer west and the Lower North Shore.
Bondi's cluster has shot up to 222 cases, with dozens of other mystery infections which have not yet been linked.

'We're making contact with our Hillsdale store team members and will provide our full support to those self-isolating in line with the advice from the NSW Health Department,' Woolworths told Daily Mail Australia in a statement.
'The safety and wellbeing of the local community is our priority, and as a food retailer, we have very high standards of cleaning and hygiene in place. The store has undergone an additional deep clean overnight.'
Other venues causing concern for state health officials includes Dan Murphy's in Gladesville on Sydney's Lower North Shore.
Anyone who visited the liquor store on Saturday June 26, from 3pm to 3.25pm is considered a casual contact and must immediately get tested and self isolate until they receive a negative result.
