The statement was published hours after the national United Firefighters Union of Australia (UFUA) called on Prime Minister Scott Morrison to abandon plans for a royal commission and instead audit and implement the findings of past inquiries.
Secretary of the South Australian United Firefighters Union (USU) Max Adlam, who is a signatory to the letter, acknowledged the difference of opinion.
“We have joined with a number of other states who feel that we need to make these statements and call for a royal commission, which I guess is at odds with the secretary of the UFUA,” Ms Adlam told SBS News.
The SA USU, Queensland USU, United Professional Firefighters Union of Western Australia and the NSW Fire Brigade Employees’ Union have broken away from the federal organisation, led by national secretary Peter Marshall, who is also the head of the Victorian branch.
In addition to the four state-based professional firefighters unions, the letter was also signed by the NSW Volunteer Firefighters Association and the Public Service Association of NSW.
“While there have been investigations and inquiries in the past, they haven't been at a national level in a comprehensive way,” Ms Adlam said.
“We do think that these are unprecedented times and fires of this veracity and heat in such a dry environment is not going to be a one-off. So, it is time for a national position to be developed in relation to matters such as coordination and resourcing.”
Urging Mr Morrison to abandon the idea, UFUA’s national secretary Mr Marshall said a royal commission was unnecessary because previous inquiries had already considered the deployment of defence personnel, the role of the Commonwealth in emergency situations, climate change and prescribed burning.
“Considerable resources are required to undertake a new, federal royal commission, including significant monetary expenditure, potentially hundreds of days of hearings, and cross-examination of witnesses," Mr Marshall said on Wednesday.
"Which is often a gruelling, emotional experience as the witness is forced to relive the trauma of the fire.”
Ms Adlam, however, said the legitimate concern of protecting witnesses from additional trauma needed to be balanced with the concern of “the trauma that is involved if we don’t get together and start organising on a national basis.”
Secretary of the NSW-based Fire Brigade Employees’ Union, Leighton Drury, agreed with Ms Adlam that a “national disaster requires a national response”.
Mr Drury said the royal commission following the 2009 Black Saturday bushfires had led to a “really good system” for managing bushfires being introduced in Victoria.
“In other states, we look to Victoria almost as a role model, they had a royal commission and got all their fire services, resources and budgeting sorted,” he said.
“That’s what we’re after, that sort of oversight and investigation into how we can follow in those footsteps.”
Victoria, along with NSW, has already announced plans for a state-based inquiry into this summer’s unprecedented fire season.
Mr Morrison is preparing to take a proposal for a bushfire royal commission to the federal cabinet. The proposed inquiry would look at the potential for a national state of emergency and how to build resilience to future fires.
