NSW Deputy Premier John Barilaro has issued a blunt warning that the much-needed tourism recovery in the bush following the drought and bushfires has to be shelved to save lives.

He has pleaded with Sydneysiders to stay away from regional NSW until the end of the year amid fears that offers of cheap accommodation will encourage people to escape the city.

"If you live in the regions you must make the tough call to tell any friends and family in the city you’ll see them at Christmas, no sooner," Mr Barilaro said.

He said his about-turn was critical in stopping the spread of COVID-19 to the regions, which have so far not been significantly impacted by the virus.
