A four-step national cabinet plan in July committed to easing of restrictions once vaccination rates reached between 70 and 80 per cent of the country's adult population.

Some COVID-free states have recently started to express different positions on the vaccination rate that would lead them to reopen borders given severe spreads of the virus in NSW in particular.

Acting-Premier Jeremy Rockliff said Tasmania continued to follow the national plan.

"But we want to ensure that every single person has had the opportunity to be vaccinated in Tasmania," he said.

"While we support the national plan, we will also be very much guided by public health advice in terms of reopening borders.

"We've had 13 deaths here in Tasmania and we don't want anyone else to die from COVID-19."

Public Health director Mark Veitch said all efforts should be made to keep COVID-19 out of Tasmanian for the time being.

He said he would ideally like to see vaccination rates in the state reach close to 90 per cent before borders reopened to the entire country.

"We should try and make sure that if a COVID case occurs in Tasmania, we don't let it spread into the community," he said.

"We know it can easily spread like wildfire. It's really hard to deal with spreading Delta strain.

"We need to try and suppress it, and if possible, eliminate it."

Dr Veitch said when vaccinations were as high as possible, health authorities would be able to provide assurances that Tasmanians could live with COVID without dire social or clinical consequences.

Meanwhile, preparations are underway for a repatriation flight from the UK of 165 returning Australians into Hobart on Sunday.
