The government has commissioned the Garvan Institute of Medical Research to carry out Tasmania-specific modelling, similar to that released by Victoria this week, which predicted Victoria's daily COVID numbers could approach 3000 by late-October.

Premier Peter Gutwein said the Tasmanian modelling and opening plan were likely to be publicly released by mid-October, within three weeks.

"We're well advanced in terms of working through what our reopening plans might be," he said.

"Releasing that modelling will provide Tasmanians with an opportunity both to consider the reopening plan, but also be fully cognisant of what the risks are going to be ... and how we attempt to manage them.

"We won't open up to the high risk areas until we are confident that all eligible Tasmanians over the age of 12 have had the opportunity to be vaccinated."

Last Friday, Mr Gutwein set a target of having 90 per cent of eligible Tasmanians to be double-dose vaccinated by December 1, and that 100 per cent of Tasmanians have had the opportunity to be vaccinated.

Director of Public Health Mark Veitch reminded Tasmanians that COVID will inevitably re-enter the state, heightening the need to be fully vaccinated.

While few other states or territories were likely to reach 90 per cent double-dose vaccinations for those eligible by December 1, the Tasmanian government is maintaining the target.

Health Department secretary Kathrine Morgan-Wicks said the state remained on track to meet it.

"If we keep booking in for vaccination at the same rates as the last six weeks, and showing up for our appointments, we will hit our 90 per cent vaccination goals," she said.

"We now want to go even bigger and better."

The six-week Delta Shield plan came to an end on Friday, in which the government ramped up vaccination centre capacity and expanded the rollout to other age groups, including high schools.

As of Thursday, 321,000 Tasmanians had received their first dose and 240,000 their second dose.

A target of 90 per cent of eligible Tasmanians comes in at 73 per cent of the total population, as children and those with medical exemptions are excluded from the figure.

The 90 per cent first dose target has been reached in those aged over 70 - at 93 per cent - with 78 per cent fully vaccinated.

For over-50s, 86 per cent have had the first dose, and 70 per cent are fully vaccinated.

In the 30-49 age bracked, 72 per cent have had the first dose, and 60 per cent of 20-29-year-olds.

The trial of a home quarantine system begins in Tasmania today, and includes those moving to Tasmania permanently from NSW provided they meet the criteria, including having their own premises to isolate in.

To be eligible, people must not have spent time time in excluded areas of NSW - about 25 local government areas, mostly in Sydney - have evidence of a negative COVID test 72 hours before travelling, have no people other than their travelling party at their premises and must be the only people in the vehicle used to travel to their premises.

That excludes taxis, Ubers and airport buses.

The waiting list for people in NSW wanting to come to Tasmania is 117, with the "vast majority" in motor homes or caravans planning to travel via the Spirit of Tasmania.

A further 100 rooms at the Ibis hotel were added for domestic quarantine on Thursday, and 108 rooms will be added at the TravelLodge next week.
