Two teenagers will be dealt with under the Youth Justice Act over a deliberately lit fire next to the Snug Beach Caravan Park.
Emergency services were called to the toilet block at the Snug foreshore, about 25 kilometres south of Hobart, at around 6pm on Thursday.
Tasmania Fire Service crews extinguished the blaze and determined it had been deliberately lit.
Tasmania Police said two youths would be proceeded against under the provisions of the Youth Justice Act.

Kingborough Council said the Snug Foreshore Public Toilets had been closed following the fire while the damage was assessed.
“The cause of the fire is being investigated and Council is assessing the damage,” the council said.

The council apologised for the inconvenience and thanked the community for its understanding.
The extent of the damage and how long the toilets will remain closed is not yet known.
