The Murrumbidgee Local Health District (MLHD) remained at zero cases as of 8pm on Tuesday as a result of 33,559 tests over the past four weeks, but virus fragments have again been detected in Temora's sewage.

NSW Health has also listed four locations in West Wyalong, Hay and Tooleybuc as potential exposure sites after an infected essential worker visited the area.

Alliance chairman John Fernando said Aboriginal people across the Riverina and Murray regions should look up their nearest clinic and get vaccinated.

"There's over 100 sites that you can attend, especially for young kids as well now that 12 years and older are eligible," he said.

"Please get out there and do that, it's about vaccinating our community, making sure that we can get together again and to do that we need to be vaccinated."

Mr Fernando said there was some hesitancy to get vaccinated in Aboriginal communities.

"We need to vaccinate our people because we can see what is happening out west; it's a serious incident."

Mr Fernando said the Riverina Medical and Dental Aboriginal Corporation was now running a vaccination clinic on Saturdays.

"All you need to do ring RivMed reception on 6923 5200, book in and please come along," he said.

Mr Fernando said anyone without the ability to make an online booking should contact their Aboriginal Medical Service, GP or vaccination clinic directly.

MLHD COVID-19 coordinator Emma Field said mobile testing clinics had been set up at West Wyalong, Hay and Tooleybuc in response to the infected person visiting those areas between August 26 and 29.

"We are encouraging anyone with the mildest of respiratory symptoms to come forward and get tested," she said.

Ms Field said the continued detection of coronavirus fragments in Temora's sewage was a great concern to the MLHD.

"This is the second detection we have had, which tells us that something is going on in that Temora area so we are really encouraging people in the town to come forward for testing."

Sewage testing is also currently undertaken weekly at Wagga, Albury, Griffith, West Wyalong, Lake Cargelligo, Gundagai and Moama. There have been no detections in these areas.

Testing is available daily at the Temora Hospital from 10am to 2pm. Please call ahead on 6980 0200.

Ms Field said the health group was "very happy" with the overall level of vaccination in the region.

"We have now delivered over 34,500 vaccines...we are seeing very big vaccination clinics and they are at capacity," she said.

"We are looking to ensure those priority populations, those people who need to be vaccinated like our health workers before the 30th of September, are coming forward for that as well."

As of last week, 60.6 per cent of Wagga's local government area population aged over 15 years had received at least one vaccine dose and 37.2 per cent had received two doses.

Ms Field said the MLHD did not have an estimate for when 70 or 80 per cent of Wagga would be fully vaccinated with two doses.
