Residents in the Riverina towns of Gundagai, Hay and Jindera have been put on alert as COVID-19 exposure sites there are listed.
The Shell Coles Express in South Gundagai and the Shell petrol station in Jindera, north of Albury, have now been added to the NSW Health's growing exposure sites list.
Anyone who visited the two locations is now considered close contacts, must immediately get tested and isolate for 14 days, regardless of the result.
In Hay the Shell Service station is listed as a 'casual contact' site.
Constuction companies in Greenacre in Sydney's southwest have also been added to the list.
The neighbouring concreting company and an excavation company on Bellfrog Street have been shut down as a staff member was positive across the sites from Thursday, July 1, until Tuesday, July 13.
