NSW Health on Sunday afternoon revealed stores across Sydney's west and south west were exposed to the virus.

They include Big W in Carnes Hill on October 4, Aldi in Edmondson Park on October 4, Chemist Warehouse in Casula on October 6 and Bunnings in Crossroads on October 7. 

Anyone who attended the venues at the listed times are defined as a casual contact and aren't required to self-isolate. 

Shoppers are advised to monitor for symptoms and get tested immediately.    

NSW Health earlier on Sunday said anyone who attended Lakemba Radiology in Sydney's south-west between 12.00pm and 2.30pm on October 1 is also considered a casual contact. 

One of the new coronavirus cases in the 24 hours to 8pm on Saturday is a social contact of a previously confirmed case from an unknown source in Sydney, NSW Health said on Sunday.

Another is linked to the Liverpool private clinic cluster and a third locally acquired case is under investigation, with people who were at Lakemba Radiology on October 1 told they are now casual contacts of a known case.

The two other cases were diagnosed in overseas travellers who are in hotel quarantine.

It comes after a nurse working at St Vincent's Hospital in Sydney tested positive to the virus.

NSW Health's Dr Michael Douglas said the nurse is believed to have acquired coronavirus outside hospital.

'The nurse provided specialised care to a single patient, and had limited contact with a very small number of colleagues,' NSW Health said in a statement on Sunday.

A second case recorded on Saturday is believed to be linked to the nurse.

There were 12,823 COVID-19 tests reported in the 24 hours to 8pm on Saturday, compared with 15,439 in the previous 24 hours.
