There are currently seven identified cases of people with COVID-19 in the Southern Highlands as of March 24.
This has been confirmed by a spokesman for the Southern Highlands Division of General Practice Dr Vince Roche.
Dr Roche told the Southern Highland News all seven cases were well enough to self-isolate at home.
He said he had been advised that all cases were related to overseas travel or cruise ships.
"There have been no cases of community transmission yet," he said.

Dr Roche said all those who had been diagnosed with COVD-19 were subject to a daily medical follow-up to keep track of their health.
He said that despite rumours there had been no situation where people had been transferred out of the region.
Dr Roche had a strict warning to share on behalf of the region's Division of General Practice.
"Keep your children home from school unless they are the child of an essential worker," he said.
"We need to get the kids out of circulation."
Dr Roche urged people not to go directly to a doctor's surgery if they had a fever, a significant cough, shortness of breath or a sore throat.
"Ideally people with flu symptoms should all talk to their GP by telephone before attending their surgery," he said.
"Their GP will organise swabbing for COVID-19 virus if this is required."
According to NSW Health, there are currently 21 to 40 confirmed cases in the South Western Sydney Local Health District.
Locations within the district include the Wingecarribee Shire, Wollondilly Shire, Campbelltown, Camden, Liverpool, Bankstown and Fairfield.
