VICTORIAN Nationals leader Peter Walsh has taken aim at the premier's "city-centric" approach to COVID-19, in light of restrictions tightening over the weekend.

Mr Walsh said the government "blindsided" food service businesses when it gave them just over 24 hours warning of the change to restrictions.

"Our local restaurants, cafes, hotels and bars have hired and rostered extra staff, stocked the fridges and worked hard to make sure they are compliant with Victoria's COVID-19 public health guidelines," Mr Walsh said.

"But Daniel Andrews is constantly shifting the goal posts and it's costing local jobs."

Mr Walsh called calling for looser restrictions in rural and regional Victoria.

"Many regional towns have never recorded a single positive coronavirus case, but Daniel Andrews has dragged us back into lockdown because of outbreaks in Melbourne," Mr Walsh said.

"The government now says it's considering a targeted lockdown of high-risk suburbs in Melbourne, but this must go both ways by allowing businesses in low risk regional towns to safely move towards business as normal."

Mildura has not recorded a new active case of COVID-19 since April, with all patients now recovered.
