A Victorian Country Fire Authority captain suspended for allegedly brutalising a 17-year-old girl in an apparent hazing ritual has claimed there are "two sides to every story".

Shocking CCTV footage of the attack seen by the ABC shows one of the volunteer brigade firefighters grabbing the teenage volunteer by her hair and shoving her headfirst to the ground, while half-a-dozen others look on.

Another firefighter kicks the girl while she is pinned down, before she is dragged under a parked fire truck and sprayed in water from its sprinklers at Eaglehawk station in Bendigo.

Brigade captain Hayden Allen is one of four men who have been stood down as a result of the attack on November 27.

"As you are aware my name has been tarnished throughout the media today," he wrote in a public Facebook post.

"Please understand that I cannot make comment on the allegations that have been accused. But like all things there is 2 (sic) sides to every story and unfortunately we just have to ride the wave."

It appears the post has since been taken down.

Three days before the attack, Mr Allen posted a Facebook profile picture of himself in his CFA uniform declaring "I will stand up, speak out and act to prevent men's violence against women" for White Ribbon Day.

CFA chief executive Frances Diver said she was sickened by the footage.

"I am horrified that a young girl has been brutalised in that way," she told Melbourne radio station 3AW.

"She's a young girl, she lives in a small town, it would be humiliating."

The CFA has ordered an independent investigation into the alleged assault and the cultural problems in the brigade, despite the girl and her family's reluctance to pursue the matter.

The CFA also referred the matter to police, but no charges will be laid as a result of their investigation.

Other members of the brigade are being questioned by the CFA.

"One of the most disturbing parts of the footage is that not only did one or two individuals engage in that behaviour, but a group of people stood by and watched the behaviour," Ms Diver said.

"There is a cultural problem that we need to address."

Treatment of 17-year-old 'appalling'

A report released in October exposed a toxic "boys club" in the ranks of the CFA, with women reporting being heckled, sexually harassed and bullied.

Victorian Emergency Services Minister James Merlino said the Andrews Government's fire services restructure was designed to improve workplace culture and diversity in the CFA.

"This behaviour is appalling and is clearly not in line with community expectations," he said.

"As Minister for Emergency Services and as a parent, I am disgusted that a 17-year-old girl has been treated in this way."

A Victorian Equal Opportunity and Human Rights Commission (VEOHRC) report into sexism and bullying in the fire services is yet to be publicly released because of a Supreme Court challenge by the United Firefighters Union (UFU).

A court decision could be made on the matter next week.

Opposition pushes Government to act

The Opposition's spokesman for Emergency Services Brad Battin did not explicitly condemn the CFA volunteers' behaviour, and instead questioned why the State Government had not intervened to force the report's release.

"A royal commission is now vital and urgent as [Daniel Andrews continues to allow bullying and harassment in our fire services to go unresolved," he said.

"Daniel Andrews needs to answer why he is failing firefighters by allowing the UFU to block a human rights report on bullying and harassment."

Volunteer Fire Brigades Victoria condemned the alleged actions of the four volunteers, and backed the Opposition's push for the VEOHRC report to be released.

"Such action is inconsistent with the professional standards of CFA members we and the public expect," a spokesman said.

"We believe that CFA and the Government should do as much as possible to expedite the release of the VEOHRC report … and pursue appropriate standards of behaviour and culture within the CFA."

The Government's controversial legislation to split the CFA volunteers and paid firefighters into separate agencies stalled in the Parliament's Upper House because Labor could not win crossbench support.
