Victoria has gone a sixth consecutive day with no new cases of coronavirus, as the state tightens its border with New Zealand due to a growing outbreak in Auckland.
The Health Department on Thursday confirmed Victoria has recorded no local or overseas acquired cases of the virus, following 18,282 tests.
There remain 16 active cases of COVID-19 in the state, four fewer than Wednesday.
It comes as authorities late on Wednesday night declared Auckland a 'red zone'.
Anyone arriving in Victoria from Auckland from Thursday will be required to enter mandatory hotel quarantine for 14 days.
Those who landed on Tuesday have been asked to get a COVID-19 test immediately and quarantine until they receive a negative test result.
At least eight cases have been linked to a cluster at a high school in Auckland, triggering a three-day lockdown.
