It comes as a record number of coronavirus tests were recorded across NSW. In the 24 hours to 8pm on Sunday, more than 38,000 people were tested.

There were another 15 COVID-19 cases reported on Monday. It brings the number of known cases in NSW to 83, all linked to the Avalon outbreak in Sydney's northern beaches.

On Monday there was a line-up of cars as people waited to be tested at the Dubbo Laverty Pathology Drive-Through Clinic. The Dubbo RSL - where the drive-through clinic is located - posted they had opened the rear gates for car park entry due to the "excessive line-up for COVID-19 testing".

The Western Health District reported that as of Monday, December 21 - 5,494 tests had been completed in the last four weeks with zero cases recorded.

"If you've got any symptoms, please get tested, change your travel plans and maybe not visit regional NSW right now until we get on top of this issue."

While encouraging everyone to take responsibility, he added that while regional health systems are handling the situation well, the last thing anyone wanted was to be overwhelmed and that's why everyone must take responsibility.

"The message is for personal responsibility- if you're not feeling well, get checked before you travel through the region."

Western NSW Health are still encouraging anyone experiencing symptoms to get themselves tested quickly and self isolate until results are known.

Symptoms may include a cough, sore or 'scratchy' throat, shortness of breath and fever

There are a variety of places to get tested including visiting your local hospital, calling a Respiratory Clinic to make an appointment, visiting a local COVID-19 testing clinic or calling your GP to see if they can perform a test, or you can visit a mobile testing service when it is in your town.

Times and locations of venues available for COVID testing are available on the NSW Health website.
