The Murrumbidgee Local Health District reported 30 new cases of the virus were found across the region in the 24 hours to 8pm on Wednesday.

Six of those cases are located in the Wagga local government area, the MLHD confirmed, with three more in the Federation LGA, two in the Murray River region and the remaining 19 being residents of Albury.

Two Wagga schools closed on Thursday after confirmation that members of their communities had been diagnosed with the virus.

Holy Trinity and Henschke primary schools will undergo deep cleaning before reopening. The MLHD is working with the Catholic Diocese of Wagga Wagga to help the schools manage the exposure.

"The school is working to identify close and casual contacts and will communicate directly with those impacted regarding testing and isolation requirements," MLHD said.

Meanwhile, fragments of the virus that causes COVID-19 continue to be found in sewage surveillance across the region.

Testing at treatment plants have returned positive results at Albury, Temora and West Wyalong in the last 24 hours.

They have also been found at Cobar, in the state's west, where there are no known cases.

The COVID-19 outbreak at Ivanhoe, located in the Far West Local Health District but closely connected to the MLHD communities of Hay and Griffith, has grown by one to 16 cases.

The interstate situation

The first-dose vaccination rate for those over 16 in the MLHD has passed 95 per cent, and 90.5 per cent of the eligible population in that age group is fully vaccinated.

More than 81 per cent of the region's youth aged between 12 and 15 have had one jab, and 62.9 per cent are fully vaccinated.

Booster doses are also now being offered to those over 18 in state-run clinics, the MLHD said.

"NSW Health state-run clinics are now offering a booster dose, using the Pfizer COVID-19 vaccine, to individuals aged 18 and over," it said.

"This booster shot will help people maintain a high level of protection against the COVID-19 virus, including the Delta variant.

"People aged 18 years and older may receive a booster at least six months after receiving their second dose of any of the COVID-19 vaccines registered for use in Australia."

Vaccinations can be booked at more than 100 providers across the Riverina by using healthdirect.gov.au.
