Four major bushfires burned more than 1,000 hectares of bushland on Thursday and Friday.

All of them were downgraded to advice level last night.

State fire controller Shane Batt said even though there were now no fire bans in place, people should remain on high alert.

"With the fires burning in very dry vegetation and difficult terrain, it has been challenging to contain them and they could still pose a problem in moderate conditions," he said.

"The bushfire season is here, and we need people to prepare their properties and review their bushfire survival plans so we are all prepared for the next run of fire weather."

Tasmania Fire Service (TFS) incident controller Mark Dobson said better conditions were forecast for Saturday and Sunday.

"We've got a cool front coming in from the west … we are expecting some rain with that, not a great deal but hopefully up to about 5 millimetres, so that should have some impact over those firegrounds," he said.

"We will still have elevated fire danger in some areas [on Saturday], so it will still be in the high range, but the wind speeds should be fairly moderate, so we should be able to get around those fires that are currently being patrolled and strengthen those containment lines further."

Volunteer firefighters feeling the pinch

Mr Dobson said bushfires in spring were now "the new normal".

"It's not unusual to have fires in October, but to have campaign fires which go for days and days is quite unusual, so it means realistically that we're looking at a five- to six-month bushfire season when it's normally about six to eight weeks."

That has put a strain on volunteer resources, with many people committed to taking care of children and doing paid work.

Peter Felmingham, a volunteer firefighter in Lachlan in the Derwent Valley, said not everyone was in a position to help so early in the season.

"It's tough. Some are able to get leave really easily, others give their time and some will lose money," he said.

He said for those who could, it was "like family".

"We're a happy bunch … some people go through problems with their marriages and things, and we bond with them over that, so a fire season is just an extension of that," Mr Felmingham said.

Austin Hawkins, 23, juggles university and a casual job with volunteer firefighting, but he said a lot of young people struggled to find the time.

"Thankfully, I have a very understanding and compassionate boss, and we have a big enough pool of staff that if I need to go away to something, there can usually be someone there pretty quickly to replace me," he said.

"But I have friends that work at much smaller businesses, and for them it's much more difficult to drop everything at the drop of a hat."

Calls for volunteer legislation

The stretch on resources has prompted calls to ensure volunteer firefighters can be released from paid work to help out on the fire front.

"We've had to bring resources down from the north-west to assist … and part of the reason for that is that other volunteers can't be released from employment," United Firefighters Union state secretary Leigh Hills said.

"The Government should be looking at, first and foremost, some sort of legislation to assist volunteers and employers of volunteers to be released from the workplace, particularly when our fire seasons will be longer in duration," he said.

He said a scheme for businesses could be established to cover workers who get called out unexpectedly with either casual staff or compensation, like in the case of Army Reserve soldiers.

"The extension of the fire season puts added pressure on the volunteers, the employers out there that employ those volunteers and their ability to get time off work to assist the fire service," he said.

Mr Hills said legislative change would also help businesses, which are used to making staffing plans around a shorter bushfire season.

Treasurer Peter Gutwein made no commitments regarding such a scheme.

"I'm aware of a range of suggestions that have been made and obviously the Government always takes these matters on notice and will consider ways we can support our volunteers into the future."
