JINDERA'S only service station is a COVID-19 exposure site after infected Sydney removalists stopped at the Shell outlet last Saturday.
NSW Health is urging those who were at the site between 11.15am and 11.45am to immediately get tested for the virus and isolate for 14 days regardless of the result because they are considered close contacts.
Those living or working at Jindera should be particularly vigilant for even the mildest of cold-like symptoms and get COVID tested
Alerts have also been issued for a Shell Roadhouse at Hay and a Coles Express at Gundagai.
Greater Hume Shire mayor Heather Wilton said news of Riverina exposure sites confirmed her suspicions.
"I really had started thinking that these people must have come through here somewhere and I didn't know where but there would have been a number of people thinking of that," Cr Wilton said.
"There are not many ways you can get from Sydney to Melbourne."
Cr Wilton urged those at the service station to get tested.
"I just hope we don't get any outbreaks because it could seriously affect us," Cr Wilton said.
Jindera-based Greater Hume Shire councillor Jenny O'Neill said she was "horrified" to learn about the exposure.
She said it would have been a busy morning in town because Jindera's football-netball club was hosting Culcairn in the Hume league last Saturday.
"I'm sure we have no reason for concern but I do hope that people are traced who called in there," Cr O'Neill said.
Cr Wilton said: "It would have been a fairly busy time for Jindera so I'm very concerned but I don't want to scare the horses."
The Jindera station and other sites had Service NSW QR code check-ins and COVID safety plans.
Those needing tests are urged to attend swab centres at Lavington Hall or the Albury Showground.
Customers at the Jindera station at the relevant time should also call 1800 943 553 unless they have already been contacted by NSW Health.
The Hay petrol station was closed for deep cleaning yesterday, calling it a "precautionary measure" in an all caps Facebook post.
"We are asking the people of Hay not to panic," it read.
"Our site is closed only as a precaution as instructed.
We are very low risk of exposure due to the processes we have in place as advised by NSW government.
"We are not immune to this disease and our processes are in place to keep the people of Hay as safe as possible."
Gundagai mayor Abb McAllister called on residents with any links to the Coles Express to be tested.
He said the situation was part of being a highway town.
"They've done a deep clean at the service station and the three staff members have all been tested and we're waiting on those result," he said.
