In a statement, acting director of public health Scott McKeown said each person's case would be assessed individually to determine their level of risk.

"Their circumstances are being managed individually depending on their movements within NSW before arriving here," he said.

Public Health is "regularly contacting" all people in Tasmania who have been in NSW since December 6 to ensure they are monitoring the risk locations.

From Sunday, anyone who enters Tasmania having spent time in the Greater Sydney region in the past 14 days is required to isolate for 14 days, barring those who have visited the northern beaches, who cannot enter Tasmania unless deemed essential travellers.

Those in the same residence would not be required to quarantine, but must ensure social distancing is carried out.

Those without a suitable residence must enter government accommodation for 14 days at their own expense.

The family-of-four diagnosed with COVID after arriving in Hobart on a repatriation flight earlier this month have recovered, Public Health has confirmed.

They were released from Fountainside Hotel on Sunday after meeting all national criteria for release and no longer being considered infectious.

It means there are no longer any confirmed cases of coronavirus in Tasmania.

Other passengers who arrived on the flight from India fly out of Hobart on Sunday, apart from one, who has a non-COVID-related medical condition.

The next mercy flight is due to arrive in Tasmania next month.

All arrivals at Tasmanian airports must complete a Tas e-travel pass if coming from anywhere other than medium or high-risk areas, which require an application under the G2G system.

Premier Peter Gutwein went through the process last week, and he said it "functions very well".

"That pass asks you a series of questions in terms of whether or not you have any symptoms, and when you arrive in Tasmania you go to a health check, you're asked if you have symptoms and you have a temperature check," he said.

In a statement, Public Health said these measures ensured Tasmania remained secure.

"There are further measures implemented at the borders to ensure compliance as well as undertake health screening," the statement reads.

"These measures have been implemented and further enhanced throughout the State's COVID response and have been proved as an important measure to help protect the Tasmanian community."
