The region, which has recorded a total of 54 COVID-19 cases since the pandemic began in March, now has just nine active cases.

Murrumbidgee Local Health District acting executive medical director Len Bruce said these patients are no longer infectious.

"We have [nine] patients who are recorded as not recovered, but that's because they've not met the public health definitions," Dr Bruce said.

"So they are not infectious anymore and they've clinically recovered. But the public health definition is stricter and that's why if you go and look on the NSW Health website we still have [nine] active cases."

Dr Bruce said the Wagga family of four who were confirmed to have the virus on August 3 were no longer infectious.

"So they can actually go out and as far as I'm aware, they have been going out and going about their business."

"There's no risk to the community at all. But it's not uncommon for people to have a sort of lagging cough after a viral infection, and it's not unique to COVID," he said.

"But the public health definition is very strict. So you have to be completely back to where you were before.

"You're not infectious [but] you still come up on statistics."

Dr Bruce said the MLHD was keeping a close eye on easing restrictions, such as those on the NSW-Victorian border.

NSW deputy premier John Barilaro announced this week an expansion of the border zone for its residents.

Border residents with permits to enter NSW previously had to stay within a 2.5 kilometre zone, but this has been extended to 50 kilometres, or 100 kilometres for agricultural workers.

Travel restrictions for residents on the NSW-Victoria border will be eased, allowing some agricultural workers to travel 100 kilometres north of the Murray River.

"There is always a concern when restrictions are relaxed," Dr Bruce said.

"As long as we as a community follow the right steps and make sure that ... if you're unwell to go get tested and isolate [while] you're waiting for the result."

Dr Bruce thanked the community for doing an "absolutely great job" in coming forward to be tested for the virus.

"By tomorrow we would reach 50,000 COVID tests, which for us would be one test for every five people that live in the Murrumbidgee which is an absolutely great achievement," he said.

"We need to stay the course. The way to defeat this virus is with early testing isolation, to make sure that, you know, we don't infect our loved ones and vulnerable members of the community."

Nine new cases of COVID-19 were diagnosed in NSW in the 24 hours to 8pm on Wednesday night, all of which were locally acquired.

No new virus cases were confirmed in the Murrumbidgee in the same time period.
