The NSW outbreak and Victorian border controls have resulted in high testing across multiple clinics.

Douglass Hanly Moir Pathology is operating a drive-through site at the Albury showgrounds, which was originally started by Murrumbidgee Local Health District when there were three cases in Lavington.

"It was the fifth of August that we started, and every three months, we kept saying that we would review," DHM regional manager Pene Jefferies said.

"We're in constant discussions with everyone about what's needed, because accessibility to testing is the thing that everybody wants.

"The showgrounds would dearly love to be able to plan to have big events again - it's quite difficult.

"We're going to just keep going.

"What everyone has now got to realise is COVID is not going away, nothing is going to be a quick fix - not even the vaccine.

"Our 'new normal' is going to be masks, testing, washing your hands, keeping your distance - what's working."

There were hundreds of cars queueing out of the showgrounds' Fallon Street entrance and onto the road during demand around Christmas.

"We went from 25 [daily tests], up to testing of 200," Ms Jefferies said.

"It was busier than the original opening, and we thought that was pretty good.

"It was people from all over the place; so many travellers, because they were hearing it on the news, and NSW Health was contacting people through their tracing.

"A lot of people were coming through and getting tested on the way home."

Murrumbidgee Local Health District's Lavington Hall COVID clinic processed 540 tests in the nine days to Monday.

Despite being closed on January 1 and 2, the service saw a spike in tests following the border closure, with 172 tests undertaken on Sunday compared to just 76 the week before.

MLHD rostered on extra staff and extended the clinic's opening hours to cope with the increased number of people seeking tests.

Albury Wodonga Health's Vermont Street clinic has also seen big demand.

Ms Jefferies said test turn-around for DHM remained at 24 hours or less, with an average of 100 being done daily since the Victorian border closure.

"It's not invasive, it doesn't hurt - it's a bit inconvenient. But most people come in and out, they're stopped for two minutes," she said.

"My team have been absolutely fantastic, when it's been disgustingly hot, they've been out here, when the storms have been on, they've been out here.

"I would far rather see more people come through and get tested, than people ignore it."

The DHM drive-through clinic is operating 8am to 1pm, Monday to Saturday - people don't need appointment to attend but should bring their Medicare card.
