MLHD Chief executive Jill Ludford said in line with advice from NSW Health, MLHD residential aged care facilities would be closed to all visitors.

"That situation will be reconsidered at midnight on Wednesday for Christmas," she said.

"Our heart goes out to families and residents who live in aged care facilities who have done it really tough during this COVID situation during the last nine months, but it is all about keeping our elderly population safe."

The new policy applies to all residential aged care run by the service including that at Berrigan Multipurpose Service, Corowa Health Service, Culcairn Multipurpose Service, Deniliquin Community Health, Deniliquin Community Health Service, Finley Hospital, Henty Multipurpose Service, Holbrook Multipurpose Service and Jerilderie Multipurpose Service.

Ms Ludford said the wider hospitals were on amber alert and all visitors must wear masks.

Ms Ludford said the disruption to the border communities over the past nine months had been traumatic and welcomed news residents could travel with just their driver's licence.

She did not think NSW needed to implement a ring of steel to separate metropolitan and regional areas like Victoria did during their second wave.

"I'm very confident in Dr Kerry Chant," she said.

"I will absolutely go by the decisions that she recommends through to government."

Ms Ludford called on residents to remain vigilant this Christmas and avoid physical contact.

"We have become a bit complacent," she said.

"Social distancing is what is going to keep us safe, please do not hug, kiss, shake hands."
