Fire crews at the ready in Tasmania

Fire fighting crews are on standby in parts of Tasmania with mild temperatures, low humidity and winds sparking a very high fire danger alert.

"Fires under these conditions can be difficult to control and only well prepared and actively defended houses can offer safety during an out of control fire," Tasmania Fire Service officer Andrew Emery said on Tuesday.

Parts of the state's east coast and southeast are at greatest risk and incident management teams are in place to deal quickly with any outbreaks.
