A bushfire emergency has been declared in a seaside town on Tasmania's east coast.
A hazard reduction burn on the outskirts of St Helens, two hours east of Launceston, has broken containment lines and firefighters are struggling to bring it back under control.
Those living in the area have been told to put bushfire emergency plans into action, with the Tasmania Fire Service saying homes are at risk from falling embers.
TFS has also warned smoke and ash will make it difficult to see and breathe.
An evacuation centre has been set up at the St Helens Football Club.
