While mainland states and territories have jumped in and out of lockdowns during the pandemic, Tasmania hasn't imposed such restrictions since a deadly cluster in the northwest early last year.

The state has recorded just one COVID-19 case in 2021, a NSW traveller who recorded a positive test in early August while in quarantine.

Premier Peter Gutwein said the state would aim to act "short and sharp" in the event of a lockdown.

"We are doing everything we possibly can to make sure we don't go into lockdown," he said on Friday.

"The plan is to provide information, so people can prepare themselves should we unfortunately need to do that."

The state government has outlined proposed restrictions and face mask wearing guidelines after calls from the business community for greater information.

"Since the beginning of last year when we had the northwest outbreak, we are the only jurisdiction in the country that has not had to go into lockdown," Mr Gutwein said.

"That has raised questions in minds about what it might look like if we need to go there again."

Mr Gutwein indicated Tasmania had learnt from outbreaks of the Delta virus strain on the mainland.

Tasmania is closed to New South Wales, Victoria, the ACT, Darwin and Katherine, New Zealand and people who've visited high-risk premises in Queensland.

Tasmania's peak tourism body has called for a system where only vaccinated people can visit the state.

Tasmania is part of a working group with Victoria and the NT which is examining the potential for vaccine passport channels.

"Every person needs to have had the opportunity to be vaccinated before we start thinking about what exemptions might be," Mr Gutwein said.

"Once we pass that threshold, I think there should be some benefits from being fully vaccinated."

Nearly 55 per cent of Tasmanians have had their first COVID-19 vaccine dose and almost 34 per cent are fully vaccinated.
