GUN owners with unwanted or unregistered firearms are being encouraged to hand them over to police this weekend.
A mobile police station will be set up in the state's South to accept unwanted firearms, but acting Detective Inspector Craig Joel said any police station statewide would accept unwanted guns at any time.
The permanent amnesty for unwanted firearms in Tasmania was introduced after the Port Arthur Massacre in 1996.
Last year police accepted 126 firearms under the amnesty, which were later destroyed.
Unregistered or stolen guns have been used in shooting incidents across the state and seized by police as part of organised crime raids.
The maximum penalty for possessing an unregistered firearm, if it is not surrendered under amnesty, is a fine of up to $6500 or up to two years' jail.
Acting Detective Inspector Joel said the mobile police station was a trial run, and it could move North.
"Definitely, next stop will be Northern Tasmania," he said.
The police command bus will be at Granton Park between 9am and 5pm today and tomorrow to accept unwanted firearms.
