Western NSW Police Commander, Assistant Commissioner Geoff McKechnie said all affected were being supported by NSW Police and the Western NSW Local Health District.

"We've taken the step of standing down one of our general duties teams that may have been working with those three officers, or in contact with them," he said.

"There's probably eight or nine [police officers] that we're looking after at the moment, and making sure they get tested."

However Assistant Commissioner McKechnie reassured the community the exposure would have no impact on policing and emergency response in the Orana Mid-Western Police District.

"But we've got 15 additional police working in Dubbo at the moment and our ADF colleagues as well," he said.

"We have more than got that covered."

On Thursday, the Assistant Commissioner said the message still wasn't getting across, with a large number of people not complying with the stay at home orders, particularly young people and those moving between Local Government Areas.

Police issued 110 infringements across the western region on Wednesday, with 35 issued in Dubbo alone.

It's believed police also apprehended a number of young people who "thought it was a good idea" to host a party in Dubbo.

"We've come to a point where we seem to be dealing with a small group of people who, no matter what the message, no matter what the urgency, don't seem to care about their actions and the implications of that for the community," he said.

In Brewarrina in the last 24-hours police also issued 12 infringements to people not abiding by the stay at home orders.

Assistant Commissioner McKechnie has pleaded with "anyone who has influence" around the actions of some of these people and communities in Dubbo and the west, to talk to them and get them to understand the dangers COVID.

"We're chasing people who are moving between our towns, COVID-19 positive cases who think it's a good idea to go to the next town and associate with people there. Again putting that whole community at risk," he said.

"When dealing with these people there seems to be a lack of care for their actions and what implications that may have for the community.

"We can write those notices all day long. But at the end of it, it needs to be people taking responsibility for their actions, and trying to protect their community, rather than put it at risk.

"I'm urging people who have any influence at all in these communities, around the actions of some of these people, to try and please talk to them and get them to understand the dangers they're placing you, themselves, and families whose communities they're in," he said.
