There have been no further cases of coronavirus identified in the Murrumbidgee Local Health District, according to information released just after 9am.
A positive test was confirmed in the border region on Sunday and remains the region's only official case.
NSW's tally rose overnight by 149 to a total of 818 on Tuesday morning.
Charles Sturt University has also confirmed a positive case, but has not yet said which campus is affected.
In response to the pandemic, the MLHD has announced that because it is moving towards doubling intensive care capacity at Griffith and Wagga base hospitals in response to COVID-19, which will involve some non-urgent elective surgery being either postponed or transferred to private facilities.
Len Bruce, the MLHD's executive director of Medical Services, said there would be no change to the hospitals' emergency and trauma theatres or urgent surgery cases.
"Elective surgery cases will be prioritised by clinicians from Wednesday, March 25," said Dr Bruce.
"The changes will apply to non-urgent cases, which include some non-urgent ear nose and throat, general surgery, urology and orthopaedic procedures.
"We are now working closely with our clinicians to prioritise these cases. We are also liaising with private providers to undertake these elective surgeries in their facilities, helping to minimise the impact on those currently waiting for a procedure."
Caesarean-section lists will continue as normal.
Remaining theatres at Griffith and Wagga will be shared amongst all specialities, including general surgery, endoscopy and vascular surgery enabling urgent and emergency cases to be prioritised, Dr Bruce said.
Elective surgery at smaller sites will carry on as normal at this stage, he said.
The MLHD's limit on hospital visitors to a maximum of one at a time remains in force.
"I know these are challenging times but the community can be assured that the District is doing absolutely everything possible to protect and maintain the health of the people of the Murrumbidgee," said Dr Bruce.
"We are in the best position possible to deal with the increased demand and with cases of COVID-19 and we will continue to keep the community updated as information becomes available," he said.
