Metro (the largest bus service in Tas) are offering free bus travel statewide on Christmas Day for everyone. A good way to get around the cities and suburbs if you're visiting from the mainland or a local.
Certainly a better way of getting home than an expensive Uber/taxi or Beam scooter if you find yourself intoxicated on the day.
Hobart, Launceston and Burnie network timetables can be found here.
Has anyone got a map of Tassie?
