The listings came just hours after Western NSW Local Health District chief executive Scott McLachlan was questioned by regional journalists about the long delay between venues of concern being identified.

Mr McLachlan said venues of concern would not be announced if contact tracers were confident everyone at a certain location had been notified.

"One of the first things we do is contact all of the people that have been in a location of concern that we know about," he said.

"If we are sure we can contact all those people, then there's no use in portraying that information publicly and concerning everyone.

"If we are also sure that someone has come into a venue and there was no chance that there was anyone else in there - say it was a service station late at night and there was no one in there - then that information is not put out publicly."

Mr McLachlan said it can be harder to contact everyone in a venue such as a supermarket or hardware store but there were still measures in place contact tracers could use to determine if someone was a close or casual contact.

"This can come from CCTV footage and a range of other things including the layout, who was in the facility and what the potential risk was," he said.

Mr McLachlan urged people to check the Western NSW Health District Facebook page and website for updates.
