Tighter restrictions imposed by the NSW Government forced the hospital to cease using doctors from Melbourne and other COVID hotspot regions in Victoria leaving AWH saying it would scramble to maintain critical services.

AWH chief executive Michael Kalimnios flagged the possibility of having to divert urgent cases, particularly via ambulance, to other centres such as Wagga.

On Wednesday he confirmed AWH was working in partnership with NSW Health in an attempt to ensure Albury Hospital could continue to offer those critical services.

"We're working collaboratively with NSW Health and are making progress in securing specialised locum staff from other locations to support Emergency Department and acute operations at Albury Hospital," Mr Kalimnios said in a statement.

The immediate impact of the staff shortage is expected to be felt in the emergency department from Thursday and in the intensive care unit in two to three weeks.

Mr Kalimnios has previously said two-thirds of the medical workforce were locums, representing up to 65 shifts a week, and these were essential to the running of the hospital.

The Border Mail has since clarified that figure is specific to the emergency department and visiting Melbourne locums will continue to work at Wodonga Hospital.

NSW's chief health officer Kerry Chant has confirmed the department had provided details to NSW locum agencies and assured locums they did not have to self-isolate to do shifts at Albury,

Dr Chant said they also had contingencies in place, but did not detail these.

"We do want to maintain services to the border communities and can I express my gratitude to the border communities," she said on Wednesday.

Meanwhile AWH also continues to make assurances to the community that it has a "comprehensive Pandemic Response Plan in place" that includes scenario planning and risk mitigation in the case of COVID-19 outbreaks for staff and patients.

The AWH plan "sits alongside larger regional and state-wide response plans that outline how health services would work collaboratively to ensure the safe continuation of critical health care services".

AWH did not respond to further questions from The Border Mail about the isolation and testing procedures in place for Melbourne locums who continue to work at Wodonga Hospital.

Nor did it respond to questions about whether these locums often only stayed for a few days at a time after Mr Kalimnios told a press conference on Tuesday they "generally have a six-week stint with AWH".
