A huge uncontrolled blaze raging on multiple fronts in central Tasmania is among scores of fires continuing to burn across the state as mainland reinforcements arrive in dribs and drabs to help put them out.
A watch and act alert remains in place for an uncontrolled fire at Miena and Central Plateau being pushed by winds and embers, Tasmania Fire Service warns.
Smoke and ash falling could threaten homes before the main fire.
Deputy Incident Controller Brett Fazackerley said the fire had been burning since Monday when lightning struck before it moved west towards the town of Miena.
"This is a very large fire now. It can almost be considered three or four fires due to the distance between different heads of the fires" Mr Fazackerley told reporters on Saturday, noting 10 people were left in Miena, about four kilometres away, ready to defend.
"The difficulty in a lot of this landscape is it is very remote. There are no existing roads or tracks. We either have to build a track to gain access into the fire or we helicopter remote teams in."
The blaze started west of Lake Fergus before it moved east and split in both southeast and northeasterly directions with about 75 firefighters working on the fire alone, he said.
More back-up is still days away with the rest of the additional 78 interstate personnel yet to join about 160 people already working to put out the scores of fires across the state.
Two major fires are still burning, with one scorching more than 20,000 hectares of wilderness near Gell River northwest of Hobart since it started on December 28 and another near Lake Fergus in the state's centre.
Both remain on advice alert levels along with another fire in the southwest.
"We are doing the best we can with our limited resources. We already have some interstate remote teams at the Gell River fire," Mr Fazackerley said.
"Until we get significant rain, these fires are going to continue to burn."
