Prime Minister Scott Morrison has conceded there is unlikely to be a breakthrough in the state border wars heading into 2021.

Mr Morrison conceded he is all but powerless to make states change their mind on border policy, dismissing the need for a National Cabinet meeting to be held.

“Their views on borders will be the same if they met this afternoon as they were a month ago,” he said.

Meanwhile New South Wales Police Minister David Elliot wants a breakthrough, critical of some states blocking entry to all residents.

“We need to make sure that we put it all into proportion, we are a nation, we’re not a collection of nation states,” Mr Elliot said.
