Southern NSW Local Health District is working with Southern Meats Goulburn to identify close and casual contacts following confirmation of a COVID-19 case linked to the abattoir on Tuesday.
It is the second case linked to the abattoir in three months.
The new case will be included in Wednesday’s numbers.
In Canberra, Chief Minister Andrew Barr confirmed on Tuesday, lockdown has been extended by four weeks in the ACT until October 15.
The extension comes as the territory recorded 22 new COVID-19 cases.
Meanwhile, two new cases were recorded in the Shoalhaven on Tuesday, two cases in Karabar (Queanbeyan), one in Yass and one new case in the Eurobodalla.
All cases are isolating at home.
There are no venues of concern for the Karabar or Batemans Bay cases at this stage.
NSW Deputy Premier John Barilaro confirmed the new positive case has been detected in Batemans Bay and said it is linked to an existing case.
"What I've been told, there are, at this stage, no exposures from these two cases in Queanbeyan and that will be the same in Batemans Bay," the Deputy Premier said.
"What I've been told is it's a close contact of a previous case," he continued.
"Is there more to be said? Possibly but at this stage on the information we've been given, we sort of, leave it."
Southern NSW Health District confirmed via a press release, the Batemans Bay case is linked to previous cases in Batemans Bay.
This brings the total number of active COVID cases in Batemans Bay to four with two cases in Cooma and two in Merimbula.
When asked about the possibility of false positive cases in Merimbula, Mr Barilaro said there was a small chance the cases in Merimbula were a false positive, and a further round of tests are being conducted.
