Hundreds of residents in the Highlands have decided to get tested, following a number of outbreaks in the South Western Sydney Local Health District.
That includes a staff member at Woolworths in Bowral who's now in self isolation.
Other cases are now linked to the Crossroads hotel at Casula, with some of those confirmed to be Tahmoor, Picton and Narellan.
The opening hours of the Bowral Hospital testing clinic have been extended from 8am to 6pm.
A pop up testing clinic will also be available at the Moss Vale Showground from 10am to 4pm from Friday to Sunday.
