A Victorian health official says it's not "exceptionally impossible" for Victorians to drive more than 10 hours through NSW with just two brief stops.
Victorians are being granted permits to return home from the ACT or Queensland through NSW, despite the border closure.
But while road safety guidelines advise stopping for at least 15 minutes every two hours, Victorian testing commander Jeroen Weimar has urged less frequent breaks.
"It is a long way but having done Cameron Corner to Mildura in a day I don't think it's an exceptionally impossible drive to do," he said on Tuesday.
Drivers could stop twice for 15 minutes, wearing a mask and keeping socially distanced from other travellers, he said.
"What we're trying to discourage is people exposing themselves to risk on a long and torturous journey with multiple stops," he said.
Mr Weimar said the health department wouldn't be encouraging people to stop overnight given widening exposure zones in NSW.
Broken Hill in the state's far west and Orange and Nyngan in central NSW have all been listed as exposure sites.
"I appreciate no-one wants to drive in a straight shot across all of NSW. Clearly we'll balance their safety ... but people are going to have some inconvenience I would suspect," he said.
Mr Weimar's comments have attracted plenty of criticism on social media and Victorian Police Minister Lisa Neville moved to clarify what he meant.
"One of the points that Jeroen was trying to make is that this isn't a leisurely drive ... get there quickly, but absolutely, you have to get there safely," Ms Neville told 3AW.
"Road safety has to be one of the priorities ... I think you can do both."
