Mr Gutwein said commercial fishing can continue, while the recreational scalloping season will not be opening.

Tasmania has 74 confirmed cases of coronavirus in the state and two confirmed deaths.

Earlier this week, Mr Gutwein announced new measures, with gatherings now restricted to two people — under threat of fines or imprisonment.

The police force will receive help from Australian Defence Force (ADF) members, as well as State Emergency Service (SES) and Tasmania Fire Service (TFS) volunteers, to carry out spot checks.

For at least the next four weeks, people are required to stay at home unless they are shopping for essential supplies, exercising, attending a medical appointment or providing support or care to another person.

They are also allowed to leave their residence to attend school or study, for work or volunteering if it cannot be done from home, to seek veterinary services for an animal, perform maintenance on another property they own, or have another "reasonable excuse" accepted by the Public Health director.

Mr Gutwein said two people had been charged under the Public Health Act so far.

A woman, 23, was charged on Wednesday night after a vehicle was allegedly broken into near the Launceston General Hospital.

Police said they were called to the area at 8:45pm and found two men and two women.

A woman was arrested and charged with a number of offences, including unlawfully possessing a dangerous article in a public place and failing to comply with a direction of the Director of Public Health.

Police alleged the woman did not have a reasonable excuse to be away from her residence.

Tasmania Police said a 29-year-old man was charged with failing to comply with the direction from the Director of Public Health after he was arrested in Launceston.

The man allegedly falsely told police officers who pulled his car over on Tuesday night that he was infected with coronavirus.

He was charged with resisting police and will also face charges under the Act.

People who fail to comply with a lawful requirement or direction of an emergency management worker can face fines of up to $16,800 or imprisonment of up to six months, or both.
