NEW South Wales local government areas of cross-border communities have been been declared orange zones by the Victorian Government from 6am on Friday.
But free movement for residents in the "border bubble" will remain in effect.
The Department of Health and Human Services (DHHS) made the announcement on Thursday afternoon, claiming the decision was made "out of an abundance of caution".
"To cross the border without a permit, cross-border community members just need to carry proof of address (such as a driver's licence)," DHHS said.
"If you do not live in the cross-border community, orange zones on the border are the same as any other orange zone in Australia, and you need to obtain an orange zone permit to re-enter Victoria (or a red zone permit if you have been in a red zone)."
