Tasmania Police is appealing for public help to return firefighting equipment stolen from crews in Launceston, in the state's north yesterday.

A total fire ban was in place in Tasmania's northern region yesterday due to very high fire danger conditions.

Crews were attending a grass fire at Dover Street in Mowbray in Launceston when a hose and a standpipe — a device used for connecting to water supplies — were stolen.

A witness has reported three young people running from the scene with the equipment.

Police say the theft hindered firefighters' ability to control the grass fire on a day with challenging conditions, and are appealing for more public information.

Tasmania fire crews attended several campsites in the north yesterday to counsel people breaching the total fire ban.

A total fire ban was in place in the northern region due to very high fire conditions for the entire day.

Fire crews attended at least three incidents at campsites at George Town, Binalong Bay and the Midlands where people had breached the ban.

Conditions have eased about the north today, but there is very high fire danger weather about south-eastern Tasmania and the Midlands.

There is no fire ban in place.
