Wagga MP Joe McGirr said it was not the right time to consider banning travel to regional areas from Greater Sydney, but added it was essential that Riverina residents remain alert.

"We have been very lucky in regional NSW so far," he said. "We have to remain vigilant. We have to keep the virus out of the regions for a long as we can."

Dr McGirr said anyone with the slightest symptoms or concerns they have been infected should stay away from regional areas.

During Tuesday's press conference, Acting Premier John Barilaro said an 18-year-old man with COVID-19 travelled to Orange, Nyngan to Broken Hill for a camping trip.

Mr Barilaro said this was an important reminder not to travel, especially to regional areas, if you have any symptoms of COVID-19.

Health Minister Brad Hazzard thanked the man for getting tested and urged anyone with any symptoms to get tested.

He also warned that areas outside of the state's capital were not immune to the threat.

"Now, the Deputy Premier has highlighted the importance of regional person to be on alert," Mr Hazzard said.

"We have this 18-year-old gentleman who came forward to tell us about his travels. This reinforces a message this is an issue for the whole of NSW.

"You can't assume just because you're in regional NSW you either don't have the virus or you're safe from the virus being transmitted to you. Any symptoms at all, go and get tested."

The Daily Advertiser put questions to NSW Health around whether it had considered banning travel to regional areas from Greater Sydney to stem the spread, but the department only issued a short statement via a spokesperson.

"NSW Health is continuing to closely monitor the evolving situation with community transmission of COVID-19 and will update our advice to the NSW Government accordingly, as we have done throughout the pandemic," the spokesperson said.

"Our priority remains protecting the health and safety of the people of NSW.

"We urge all residents and visitors across NSW, including in the regions, to practise COVID-safe behaviours and get tested even with mild symptoms."
