Victoria has introduced a strict new border entry permit system for NSW residents to begin from 12.01am on Saturday.

Premier Daniel Andrews also declared Sydney’s northern beaches a coronavirus hotpot on Friday meaning anyone who has visited the area on or since December 11 will not be welcomed into the state and forced into quarantine.

Everyone else in NSW wanting to enter Victoria from 12.01am Saturday will be required to fill out a border entry permit.

Many people have expressed confusion at the new process on social media but Victorian health officials said the application would be identical to the recent form used to process travellers from Adelaide during its recent outbreak.

The form is available on the Department of Health and Human Services site here, but the form won’t go live until 12.01am on Saturday.

According to health authorities, the form will take five minutes to complete and is essentially a declaration the traveller hasn’t been compromised by the northern beaches outbreak.

“Regardless of your place of residence, from midnight tonight, anyone travelling from NSW into Victoria will need a permit,” the DHHS said.

The form breaks down travellers into three categories — red zone, orange zone and green zone.

The red zone applies to areas who have visited the northern beaches as well as other sites in Sydney that have been declared a close contact to a known case.

Orange zone is anyone who has been in greater Sydney. They are being told to isolate when they enter Victoria and remain isolated until a negative coronavirus test is returned.

The green zone applies to the rest of NSW, with those told to get a test only if they have coronavirus symptoms.

South Australia will also reintroduce its cross-border travel application process for anyone entering the state.

The application process includes a question on whether or not the traveller has visited a NSW hotspot since Friday December 11.

Premier Steven Marshall told reporters SA’s health authorities would continue to monitor the Sydney outbreak.

“We are watching very carefully, but we are also getting excellent (contact tracing) information flowing through from NSW Health,” he said.

SA officials urge prospective travellers to monitor the NSW Health website for updates.
