SOME interstate firefighters helping fight Tasmania's bushfires may be sent home as temperatures rise in their home states.
Dozens of firefighters have been sent to Tasmania from around the country, after the state's worst fires in 45 years destroyed more than 130 homes, concentrated in the town of Dunalley, east of Hobart.
Among them was Victorian man Peter Cramer, 61, who died while working on foot to identify potential containment lines on the southern boundary of the Forcett fire on Sunday.
A fresh contingent of about 68 firefighters from around the country arrived in Tasmania yesterday, and helped local crews battle five major bushfires still burning across the state.
They relieved 67 Victorian firefighters who returned to Melbourne this morning.
Several advice notices remain in place, but no emergency or watch and act warnings were issued.
Tasmania Fire Service spokesman Paul Symington said the fires did not present a major threat, but he said crews would be working hard to strengthen containment lines, especially around the Forcett fire.
"Things have quietened down, but having said that, it will get hotter on Thursday," he told AAP.
Hobart is expected to reach a top of 30C on Thursday, but the Bureau of Meteorology says there is also a strong possibility of rain.
The temperature is predicted to soar across southeastern Australia on Thursday, which Mr Symington said would prompt a review of the use of interstate firefighters.
"We're looking at what resources we need, and if possible we'll start to release some of them, because we know they'll be getting short up there as well," he said.
