Residents in Orange, Cabonne and Blayney LGAs were told on Tuesday night there would be stay-at-home orders in place for seven-days, with residents from other areas such as Dubbo who visited those towns also subject to the orders. Five venues of concern were also highlighted.

Western NSW Local Health District chief executive, Scott McLachlan, said the QR codes and check in process has become their "best friend" in contact tracing.

"Contact tracing has been underway for the last 24 hours with the list of people who were at those five venues," Mr McLachlan said.

"All of those people have now been contacted via text message and requested to both isolate and come in for a COVID test immediately.

"From the QR code check-in process that the confirmed case has identified for us ... we're confident from all of the check-ins that he did with the QR codes that that's the extent of the locations."

He did add that through further contact tracing and testing, they will continue determine whether there are any other places that might need to be identified.

"I don't want us to see any further spread in Western NSW and the steps we have taken have been the right ones."

He added that should it be necessary, the ability to scale up further testing clinics is possible.

While stay at home orders are in force for the three LGAs, and anyone who visited the area since Saturday, Police have also launched an operation to ensure compliance.

Regional NSW field operations Deputy Commissioner Mick Willing said police were there to support the region during this time of uncertainty, and are used to working with communities to ensure compliance.

"Our officers do not want to issue fines - they want to see everyone abiding by the public health orders, as they were introduced for the health and safety of everyone.
