Crews in Tasmania's south-east are still trying to rein in several fire fronts fanned by increasing winds.

Firefighters made the most of calm conditions earlier, downgrading fires at Curries River and Mathinna to no alert level.

Fire service spokesman Phil Douglas says the peninsula fires are still the greatest threat.

There has been a flare up on the fire's north-east front, towards Kellevie, Bream Creek and Marion Bay.

"We're also asking the residents south of Eaglehawk Neck along Blowhole Road and Doo Town to also watch what's going on," he said.

"There's no immediate threat to communities, but we are getting a little heightened activity inside those boundaries."

The fire service is reassuring residents who have just returned to their homes and are anxious about smoke in the area.

Mr Douglas says some residents are calling triple 0.

"A lot of those plumes of smoke are from back-burning and the consolidation of fire boundaries and we don't want to be receiving unnecessary triple 0 calls, and if they do have a concern in the first instance talk to those crews.

The blaze which began at Forcett last week is still at the watch and act level, while advice warnings remain in place for six fires.

Two major fires are also still burning at Lake Repulse and Montumana. They are at the advice level.

Bushfire information:

Burn-offs questioned

The Tasmania Fire Service has again been questioned about the adequacy of fuel reduction burn-offs in the lead-up to last week's bushfire emergency.

Community meetings in fire-ravaged areas are turning from information sessions to inquisitions, with a growing chorus of criticism about a perceived lack of burn-offs during cooler months.

2011 and 2010 were the wettest years Tasmania has experienced in the past two decades, increasing fuel loads which dried off at the end of 2012.

Chief fire officer Mike Brown says now is not the time to discuss fuel-reduction, but he stressed individual property owners also have a responsibility.

"I would think that there's less fuel-reduction done now that there would have been 20 or 30 years ago," he said.

"But I think we've got to understand that large areas of these fires were on private property and if you own the land, you own the fuel and you own the risk."

He says Tasmania will still be in a critical fire danger period for the next eight to 12 weeks.

"We can not afford to relax, in fact we need to increase out vigilance and step up our preparations."

Tasmania's Emergency Management Minister says strategic fuel reduction is done in collaboration with the fire service.

David O'Byrne says most of the area burnt by the two most destructive fires was private property.

"Fuel-reduction is a shared responsibility," he said.

"What we saw in the two major incidents at Dunalley and the Forcett fire and also at Lake Repulse, 80 per cent of that land was privately-owned.

"So it is a shared responsibility between the tiers of Government and also private land-owners as well."

About 170 properties more than 100,000 hectares have been destroyed in the past week.

Residents of Dunalley which was the hardest hit town raised the issue earlier this week.
