Almost 50 fires continue to burn across Tasmania as the Bureau of Meteorology forecasts hot temperatures and dry thunderstorms for Friday.
Tasmanians are being told they must be physically and mentally prepared if they choose to defend their homes against potentially devastating wildfires.
Some 55,0000 hectares of wilderness and bushland across the state has been ravaged by scores of fires, at least one of which has been burning since late December.One house near Miena in central Tasmania, has been lost, and conditions across the state are forecast to worsen over coming days, increasing the threat to property and life.
"The house lost in Miena is probably a property that we thought would be defendable, but was lost due to ember attack," State Fire Controller Bruce Byatt told reporters on Wednesday.
"We had fire crews in place on that fire and when it became untenable, the residents and the fire crews all needed to withdraw."
The property was surrounded by cleared land, untouched by fire, and the house had roof sprinklers. But falling embers meant the residents, even with the help of firefighters, had to flee to safety.
No one was injured.
Almost 50 fires continue to burn, many in central parts of the state and some prompting repeated emergency warnings for nearby residents of townships including Miena, Barren Tier, Tods Corner, Penstock Lagoon, Liawenee and Shannon.
"If you decide to stay and defend your property, make sure that you both physically and mentally are prepared to do it," Mr Byatt said.
"It is not a simple task and you need to consider it very carefully."
A major fire still burns near Gell River, northwest of Hobart, scorching more than 20,000 hectares of wilderness since it started on December 28. Another blaze burns near Lake Fergus in the state's centre.
Police will join the fire battle on Friday, stepping up patrols of high-risk sites including camping and recreation areas and have asked for the public to report any suspicious behaviour.
"Timely information, including descriptions of people and vehicle registrations in the area concerned, is invaluable in the investigation of deliberately-lit fires," Tasmania Police Assistant Commissioner Richard Cowling said.
A total fire ban is in place for all of Tasmania, starting Thursday until Monday.
The Bureau of Meteorology is forecasting temperatures of up to the high-30s on Friday, together with dry thunderstorms.
"Strong and gusty northwesterly winds are expected to develop on Friday which, combined with the hot temperatures, will see very high to severe fire dangers develop about southern, central and eastern parts of Tasmania," the bureau said in a statement.

The Tourism Council of Tasmania urged visitors they may need to change plans because of the fires.
"If the decision is made to close further National Parks, tracks and camp grounds, there will obviously be a lot of campers and walkers who will need alternative accommodation arrangements," Tourism Council chief executive Luke Martin said.
