Australia has marked some positive coronavirus milestones as restrictions continue to ease across the country.

People from NSW will be able to travel to Tasmania from Friday for the first time in seven months.

The island state is now open to all other parts of Australia except for Victoria, with plans to lift that restriction on December 1.

While Western Australia’s border is due to open for visitors bar NSW and Victoria from November 14, the High Court is set to announce its decision on Clive Palmer’s battle against the closure.

The High Court is on Friday also set to hear another constitutional case related to coronavirus restrictions.

Victoria is defending a challenge to Melbourne’s coronavirus lockdown on the ground a right to freedom of movement doesn’t exist in the constitution.

Melbourne’s lockdown lifted last week, with Victoria since recording six consecutive days of no new cases or deaths from the virus.

The state has also confirmed there are no more active cases in its aged care system, marking a significant achievement after the sector bore the brunt of Victoria’s second virus outbreak.

The last active case was cleared on Wednesday afternoon, making it the first time since June 15 the sector was virus free.

Of Victoria’s 819 coronavirus deaths, more than 650 are related to aged care.

On Thursday, the national incident centre confirmed Australia had again recorded a zero community transmission day.

Health Minister Greg Hunt said the milestone came at time when the world had recorded its second highest daily global case numbers, and the highest daily death toll.

Public health agencies reported 8001 new deaths and 489,944 new cases worldwide.

Australia now has four vaccine agreements, with manufacturing of the first medicine to start in Melbourne next week.
