Dr McGirr signed a joint letter with five other MPs that called on Prime Minister Scott Morrison to help end the "ad-hoc state government border closures".

The letter was also sent to NSW Premier Gladys Berejiklian and her Victorian counterpart Daniel Andrews.

"Our offices have been inundated with thousands of constituents confused about rapidly changing state border regulations," the letter stated.

"A consistent, federal government-led national approach to state border management would help ease anxieties and allow communities to plan for future border closures."

Dr McGirr described Victoria's decision to shut the border with NSW at short notice as "frankly, a shambles".

The MPs' letter called for a federal minister to set guidelines on border closures and the definitions of COVID-19 'hotspot' and 'border bubbles', and ensure information was provided to the community.

Junee woman Kate Hinds, who this month encountered great difficulty getting her 88-year-old father Charlie home to Tasmania after he was denied transit via Melbourne, said she would welcome better communication.

"COVID has been around now for a year but it seems like no-one has any of their contingencies in place, particularly in Victoria," she said.

Mr Morrison told 2GB radio this week that premiers were responsible for public health in their own states but he would encourage them "to get some greater transparency and predictability" around border closures.

Business NSW Murray-Riverina regional manager Anthony McFarlane said better guidelines and clarity could help reduce damage to the region's economy if there were new border closures.

"I met with businesses [on Tuesday] in Moama and Deniliquin and the most recent border closure on New Year's Eve caused significant disruption to the visitor economy...they were given very short notice," he said.

The letter was also signed by state-level independent and minor party MPs on both sides of the NSW-Victorian border, including Shooters, Fishers and Farmers Party Murray MP Helen Dalton.

Mrs Dalton said NSW Border towns would "not survive another year of random, rushed state border closures" and called for "some rules and protections" from the federal government.
