Mayor Katrina Humphries said the "dreadful infection rates" had forced council to ask residents to voluntarily stay at home, work from home, close shops and get off the streets.

"We need to take the pressure off our medical teams and try to take the sting out of this awful situation we are in," she said in a letter signed off on by most shire councillors on Thursday evening.

"I call for this voluntary 'get off the streets' to start as quickly as possible tonight for review on Monday."

"The harvest is underway and really needs to continue."

She said the virus was running rampant in the community and Moree needed a chance to beat it, particularly as the vaccination rates in the local government area lag behind at just under 80 per cent double dose.
