The Tasmania Fire Service has issued a bushfire warning for Rokeby, with large orange flames visible across the area.
The fire on Kotona Street is travelling towards Mount Rumney.
There is no immediate threat, but conditions are expected to be changeable.
“Well prepared homes are expected to be defendable in these conditions,” the fire service said.
Residents with a bushfire plan are urged to check it now.
Those who are not well prepared should plan to leave for a safer place if conditions deteriorate.
The fire service is advising residents to monitor conditions closely.
The alert follows recent deliberate lighting of three bushfires in bushland between Clarendon Vale and Acton Park.
Those fires required significant firefighting resources including three waterbombing helicopters and ground crews from six brigades.
Sergeant Jake Sansom from Clarence Plains police station confirmed the blazes were deliberately lit.
“The incidents occurred on a high fire danger day and required significant firefighting resources, including multiple aerial assets, to bring the fires under control,” he said.
“This behaviour posed a serious risk to the community and is completely unacceptable.”
