There will not be any changes to the role of Country Fire Authority volunteers under the new enterprise agreement, but its new board will need to help change the culture within the organisation, Victorian Premier Daniel Andrews has said.

The Government moved to sack the CFA's board on Friday after it failed to sign up to a controversial new pay deal for professional firefighters.

There were concerns among some volunteers and local communities that the agreement would give too much power to the United Firefighters Union, and paid firefighters would replace the work of volunteers.

But Mr Andrews said the idea was "nonsense", and there would only be 350 new paid positions under the agreement at brigades that were already integrated.

Of the 1,200 local brigades across the state, 34 of them have a mix of paid firefighters and volunteers.

"Those 34 integrated stations in the growth corridors of Melbourne, in big regional centres, where volunteers and career firefighters, all professional, all committed, they work together to keep their community safe," he told 774 ABC Melbourne.

"Our volunteers are absolute heroes … but this notion that if you're a paid firefighter and you dare be a member of the union, you're a somehow a thug, I won't have that. It's just wrong."

Mr Andrews said there were safeguards in place that would ensure volunteers would not be compromised.

"Who would want to do that [compromise volunteer safety]? Of course we would never do that. I think these changes, more firefighters turning out to dangerous fires, far from compromising safety, that will enhance safety," he said.

New CFA board to address 'cultural challenges'

The Premier said a new board would be appointed by the end of the week and any further action made against the CFA's current management team would be its responsibility, refusing to say whether he backed chief executive Lucinda Nolan.

Mr Andrews said the CFA also needed a culture change.

"We've got a human rights and equal opportunity commission report from last year that is scathing, we've got the fallout from Fiskville and the terribly incompetent way that was handled," he said.

"There are many, many challenges in the CFA and they need to be addressed, and a new board will be appointed and they will be able to address those issues."
