Police on both sides of the border have been working through Monday's announcement of border closures to determine how the measures will be enforced.
NSW officers and the army will prevent people entering the state from Victoria without a permit, but NSW premier Gladys Berejiklian said it would take two or three days for a permit system to be created.
Drones will monitor crossing points with the closure enforced on the NSW side from 11.59pm on Tuesday.
Albury officers held meetings on Monday to determine how the shutdown would operate.
Police in the Wodonga region, and surrounding Victorian border towns, were awaiting details from NSW.
Victorian Acting Superintendent Pauline Williams said it was a developing situation.
"We're certainly working with NSW Police on what the border crossing will look like," she said.
"We're getting information coming through.
"We're working with the information we have at hand and as it unfolds."
Albury police could not be contacted.
Ms Berejiklian said border communities would be particularly impacted by the closures in coming days, while NSW Police Commissioner Mick Fuller said crossing the river would be difficult, but not impossible.
Commissioner Fuller said police would take a "sensible but pragmatic approach" when assessing if people could cross and said a wide range of resources would be used to monitor the closures.
"We want people to take this seriously," he said.
"Do not underestimate the pain all Victorians are going through, we don't want that in NSW."
Most crossing points will be manned.
"Now clearly, it's a very long border," Commissioner Fuller said.
"Someone could choose to swim across the river, walk through the bush.
"There are dirt tracks, we'll be using drones and other aerial surveillance at the same time.
"We'll be focusing no doubt on the primary arterial roads because we know that's where most of the vehicle traffic comes from but nevertheless there will be police, defence and other emergency service workers across a majority of those crossings and there will be aerial and other surveillance 24/7 right across that border."
He said police were seeking additional powers to turn people around at the border and fine those who were misled police when seeking exemptions.
Police also want to have the power to issue fines to those who enter NSW from high risk COVID-19 areas in Victoria.
