From 11.59pm tonight, anyone trying to enter Victoria from NSW will be required to apply for a permit. The new rule applies to NSW residents, residents of other states who are travelling through NSW and Victorian residents who are returning home from NSW. Anyone trying to enter who has recently visited the northern beaches region of Sydney, or other areas declared "red zones" (areas that have been exposed to the virus), won't be allowed into the state. Permits will be checked at both ends of the journey.

At the time of writing, the NSW Government had just announced a number of other locations in Sydney that have been visited by Covid-19 cases, including cafes in the eastern suburbs, Westfield Bondi Junction and an office building in Eveleigh. Find the full list here.

Greater Sydney has been declared an orange zone, with visitors from that region encouraged to get tested upon arrival and self-quarantine until they have received their results. And travellers from regional NSW are being asked to monitor their symptoms.

Victorian residents, meanwhile, are being asked to cancel any holiday plans to NSW. "The situation up there is expected to get worse over the coming days and the red zone is likely to grow," Victorian premier Dan Andrews wrote in a Tweet. "That means we cannot guarantee you'll be able to come back.

"I know these changes will affect some people's plans for the holidays – and I'm sorry about that. In such a hard year, so many of us have been counting down until we get to see those we've missed so much. But no family gathering is worth more than someone's life."

Victoria currently has eight active coronavirus cases – all of which are returned travellers in hotel quarantine. New South Wales, meanwhile, has reported 28 new community cases over the past couple of days.
