On Tuesday Kooringal's Sacred Heart Primary School closed its premises to undergo deep cleaning and contact tracing after a member of the school community tested positive to COVID-19.

The Murrumbidgee Local Health District's COVID-19 coordinator Emma Field confirmed that 61 close contacts have been identified from this exposure.

A further two schools in Wagga had to close on Thursday - Holy Trinity Primary School and Henschke Primary School - and Ms Field said these venues are still under investigation to determine how many close contacts there are, and when the schools were visited by COVID-positive people.

"We're working very closely with the schools and the schools are currently under investigation with [NSW Health] and they've sent out advice," she added.

Ms Field encouraged any families part of the three school communities to follow the advice of the schools.

"They will send out letters to each and every student who is currently affected," she said.

Ms Field said that it doesn't appear that the cases at each three schools are linked to each other.

"We know that we've got siblings and there are some linkages within the schools, that's for sure, but at this point in time we wouldn't want to speculate," she said.

"At this point they're not high numbers but ... a positive is a positive."

With children under 12 currently not able to be vaccinated against the virus, Ms Field is encouraging those aged between 12 and 16 to roll up their sleeves for the jab, saying there is a "protective factor" for younger siblings in the household.

The ongoing COVID outbreak in Albury has skewed noticeably younger, with many school-aged children becoming infected. Ms Field said that cases in Wagga appear more varied, with younger children and adults included in the cases.

'We're not seeing a cluster ... with the small numbers that we've got," she said, with Albury's case numbers significantly higher than Wagga's.

Meanwhile, there have been no further cases of the virus stemming from a funeral in Tolland reported earlier in the week.

Ms Field said that two cases in Wagga are linked to the individual who attended the funeral, but the cases were not in attendance themselves.

In response to growing cases in Wagga, with six new cases reported on Thursday, the MLHD is reopening its drive-through testing clinic at the Wagga Showgrounds.

The Equex Centre drive-through clinic was closed last Friday, with local health officials stating that testing capacity could be met at the testing clinic on Murray Street.

The new drive-through clinic opened around 3pm on Thursday and will be open until 6pm at the Showgrounds, operating 10am-6pm thereafter.

Ms Field said the reason it wasn't reopened at the Equex Centre like before is because community sport has returned, following the recent lockdown and easing of restrictions roadmap.

"The Equex model was only ever for that lockdown period and that was only available for that time," she said.

"We knew the date that we had to work with, so the drive-through was then taken from that location for that reason."

Ms Field said that vaccination against COVID-19 is "the key" moving forward, and said if we were experiencing the current outbreak 12 months ago, before vaccination, "we would have seen a very different outcome".

"This time last year if we had the current outbreak, our hospitalisations would be much bigger," she said.
