On Friday night, the Tasmanian Government released a statement announcing a fifth case of coronavirus had been diagnosed. The person has been admitted to Royal Hobart Hospital.

Earlier, a woman in her 40s was confirmed as the fourth person with coronavirus in Tasmania and the second in the north of the state.

Public Health director Mark Veitch said the woman arrived from the Philippines on March 8, before travelling to Launceston from Melbourne on JQ731 the following day.

Dr Veitch said she returned a positive result on Wednesday afternoon and was in a stable condition.

"This fourth case is unrelated to any of the three preceding cases in Tasmania," he said.

"This infection is not due to local transmission in Tasmania."

He said people seated near the woman on the flight to Launceston would be contacted and asked to self-isolate.

She is currently in isolation in accommodation provided by the University of Tasmania at its Newnham campus in Launceston.

Public Health said the student was well supported and there was no risk to others on campus.

It said campus operations could continue as normal.

"There's no risk to other people on the campus and normal campus activities continue," Dr Veitch said.

"This lady is well and she was provided with a facility at UTAS to stay in while her test was conducted.

"It's a self-contained unit and it poses no risk to the wider community."

Writing to students, the university said that it had "a clear plan when there is local transmission in Tasmania".

"We will move to online delivery of teaching to the greatest extent possible, a model to rotate people to work from home where possible and careful management of those circumstances where people need to work on campus."

It said the current case is not one of local transmission.

The new cases follow the diagnosis of a Hobart-based UTAS student in her 30s, a Nepalese man in his 20s and a 40-year-old who had recently returned to Launceston from Iran.

Dr Veitch said the public health hotline had seen a huge surge in demand, which meant some callers reached the voicemail.

He said voicemail messages were subsequently compiled, but on some occasions it would take more than 24 hours to return calls.

Tasmanian Premier Peter Gutwein said the state was ready.

"We are prepared in terms of our health service, [we are engaged] in terms of our business community and as a government," he said.

"We'll have a further package to announce next week in support of the federal stimulus package.

"The package I believe has landed very well. It will support over 190,000 Tasmanians with direct payments, and the many small businesses we have in Tasmania will benefit as well.

He said one focus was alleviating payroll tax.

"[It's] certainly something that's on our list, and we're working through that," said Mr Gutwein.

"What we want to ensure is that our businesses have cash flow, that they can continue to employ Tasmanians, and importantly that confidence remains across the business sector."

Opposition wants 'verified' advice

Labor health spokeswoman Sarah Lovell called on the Government to provide clearer advice to Tasmanians.

Ms Lovell said Labor MPs had experienced a sharp increase in calls from concerned community members to their electorate offices in recent days.

"There are many members of the community who are feeling very concerned and in some cases very distressed, about the potential impact that coronavirus may have on our community," she said.

"There are questions around what social distancing measures should be put in place right now, [and] whether schools should be looking at closing.

"[There are questions about] whether the university should be looking at closing, whether small events should be canceled, [and] whether Salamanca Market should go ahead as planned.

"These questions need to be answered by verified information through verified channels."

Health Minister Sarah Courtney said on Thursday that Tasmanians should "get on with life".

"To date in Tasmania, we have not had community transmission," she said.

"We want to see life go on for Tasmanians, and that's what we're encouraging Tasmanians to do.

"If that situation changes, if risk profiles change, we will update people accordingly."
