And two new Bathurst businesses - a menswear shop and a butchery - have been added to NSW Health's venues of concern.

Western NSW Local Health District reported two new cases of COVID-19 in the 24 hours to 8pm on Thursday, including one that was infectious in the community.

Those cases were confirmed as it was revealed the Assumption School at West Bathurst had been closed to all staff and students on Friday after a positive COVID case was detected among the school community.

But about lunchtime on Friday health authorities confirmed five more local cases of COVID detected since the 8pm cut-off on Thursday. The new cases will be included in Saturday's figures.

Health district chief executive Scott McLachlan said the evolving situation was a reminder that COVID-19 was still creeping around communities across the district and he urged Bathurst residents to come forward for testing.

"Case investigations are ongoing, however, we have identified that a number of these new cases were infectious in the community so I'm urging anyone who might have any concerns to get tested immediately," Mr McLachlan said.

"Contact tracing is ongoing but there have been a number of venues of concern already identified. These will be published in the coming hours and we expect more exposure sites to be identified as investigations continue.

"We know The Assumption School has been impacted and we continue to work closely with the NSW Department of Education to complete venue risk assessments and ensure the safety of students, staff and the community.

"We know at least one childcare centre and one sporting club are also impacted, with investigations continuing, so I urge everyone to stay up to date with any venues of concern by visiting the NSW Health website and keeping a close eye on WNSWLHD social media platforms."

Anyone who visited Bent Threads Menswear in William Street between 4.18pm and 4.25pm on Tuesday, October 19 or 4.30pm and 5.30pm on Thursday, October 21; or Steve's Quality Meats at the Westpoint Shopping Centre between 3.45pm and 3.50pm on Wednesday, October 20 or 3.45pm and 3.50pm on Thursday, October 21 should get tested immediately and self-isolate until they get a negative result.

Drive-through COVID testing is available from 8am-4pm each day at the former Clancy Motors site at 252 Howick Street.

"Surveillance testing is also available so anyone who may have concerns can get tested too. But if you are not symptomatic, consider self-isolating until tomorrow to ensure those who are symptomatic or identified as contacts can get tested as a priority," Mr McLachlan said.

"Please be patient when you come to get tested. With more demand we are increasing capacity at the drive-through testing site however there could be queues, so please sit tight, wait your turn and make sure you get your test.

"Also, please make sure you have your smartphone with you when you go to get tested at the Howick Street site. This helps make the registration process a lot quicker so you can get your test done as soon as possible.

"I want to assure the community this is not a reason to panic, but to be cautious and aware, particularly coming into the weekend. Widespread testing is crucial to stopping any spread of COVID-19 and we all have a responsibility to help keep our community safe."
