Murrumbidgee Local Health District's Tracey Oakman says there is a risk people in the Border community could have COVID-19.
Asked if she was expecting positive COVID cases to be detected in the community, Ms Oakman said "there's always that risk."
"I'm not particularly expecting it or not expecting it," she said.
"It just depends on how much contact they managed to have with the case."
Ms Oakman said at the time the removalists were in the Hay Shell, no other customers were inside, and only a few people were inside the Jindera service station when the removalists were.
The Gundagai exposure site was busier.

"There wasn't lots and lots of people going through but there's always the potential," Ms Oakman said.
"And then what if those people do become positive, how fast have they been tested before they spread it to other people?"
Ms Oakman said the exposures showed the importance of being COVID-safe even in areas which haven't had a positive case in months.
"This information goes to show our area, although we haven't had a positive case in our region, it can't be assume there are no cases in our area," she said.
"We just need to be really vigilant both with our mask wearing and our social distancing and we encourage everyone to get tested particularly if you have symptoms but if you're unsure - get tested."
Asked what her reaction was to the news the removalists had been in the region, Ms Oakman said she was disappointed.
"But we know that happens, people who don't know they've got COVID go about their business and it was a business trip for these people," she said.
"That's a risk we have. We were expecting it even though it's disappointing."
Ms Oakman said she had no idea why the removalists had been so uncooperative or why they were in Jindera.
"The more people can tell us the faster we can get that information out," she said.
"The more delay [we have] the higher the potential is for having cases in our community."
Ms Oakman encouraged anyone who had been at the exposure sites who had not been identified by MLHD to come forward and get tested.
She praised the residents who had taken the initiative to get tested.
"Hats off to them," she said.
"They're community minded, they're absolutely doing the right thing.
"We want people to protect everyone else in the community as well.
"Those people going forward and doing that are protecting their families, they're protecting their friends and their colleagues by getting tested - because if they are positive we can track it down really fast, and if they are negative, they'll know they're negative."
Ms Oakman said QR codes were the one tool NSW Health had to rapidly contact people who might have been exposed to COVID so it was vital people checked-in.
She advised residents and community groups to follow the NSW Public Health requirements.
"Follow the rules and we'll stay as safe as we can," she said.
