Testing numbers in Dubbo have risen since Friday's introduction of surveillance testing, while there's been a "huge boom" in the number of vaccinations.
There were six cases in Dubbo up to 8pm on Sunday, and 10 across the Western NSW Local Health District.
None of Dubbo's six cases were infectious while in the community - they were either household contacts or in isolation.
The city's total number of cases has reached 767, with 1073 in the Western region health district. There are eight people in hospital in Dubbo, five in ICU and three who have been ventilated.
The local health chief Scott McLachlan said although there were some positive signs, he was still feeling "very cautious".
"We know that in the last...10 days there's been quite a few people infectious in the community," Mr McLachlan said. "It was good to see testing numbers right up at the weekend...I think that was a good rise with the surveillance testing available."
There were 2,680 tests conducted in Dubbo at the weekend.
"Part of the answer has definitely been surveillance testing, we saw a bit of a bump in the last few days," Member for Dubbo Dugald Saunders said.
The weekend saw the final days of the ADF second-dose vaccination clinic in Dubbo, which also offered first doses to those who missed out the first time around.
The ADF have so far administered 37,000 jabs across the region, and will remain here until the end of October.
"It's fair to say we've seen a huge boom in the number of people getting vaccinated in the last week...across the region we'd be pushing well over 80 per cent as an average, some communities up around 85 - 90 per cent of first doses," Mr Mclachlan said.
Vaccination figures are expected to be released on Tuesday.
One of the four local police officers who contracted COVID returned to work on Monday, and Western Region Commander, Assistant Commissioner Geoff McKechnie said they were able to contain the outbreak to those original four officers.
"Our workforce hasn't been impacted significantly...we just need to be careful into the future about how we protect our officers," he said.
There have been no additional cases at Holy Spirit or St Mary's Villa aged care facilities.
