A high visibility operation is in effect to catch wrongdoers and keep the community safe, Oxley Police District Superintendent Kylie Endemi said.

"The message is clear, we are out, all of our resources are out patrolling to keep the community safe at this particular time - we will continue to do that and we won't hesitate to take action if people are non-compliant with these public health orders," she said.

"We will be relentless, we have all the resources that we need, we are highly visible visiting any location where we think there may be gatherings of people, or potentially people in contravention of the public health order.

"We are being proactive."

Police responded to a noise complaint at a house party on Edward Street, Gunnedah, in the early hours of Saturday morning and handed out 11 infringement notices.

No more than five visitors are allowed in a home across the state; a restriction that has been in place for at least three weeks.

At an RBT in Willow Tree, officers pulled over two separate drivers who had left the Greater Sydney area.

On Saturday afternoon a male driver was identified as having been in the Greater Sydney area without a reasonable excuse or essential reason to travel; he was fined and sent home.

Another male driver was identified on the Sunday afternoon, who told police he had the intention to work outside the region but had not had a COVID-19 test in the seven days before leaving.

The aim is to keep the community safe, Superintendent Endemi said, but cops won't hesitate to hand out infringements to people who break the rules.

"We have over the course of the last week or so also issued five infringement notices for people who have failed to wear a mask without a reasonable excuse to do so," she said.

"There is absolutely a risk, we are not immune in regional NSW and we have to remember that.

"Work with us, don't give us a reason to have to interact with you because you are being non-compliant."

Police urge the public to report incidents of non-compliance with the public health orders to keep the community safe.
