Finance Minister Simon Birmingham, whose department manages much of Parliament House, said the conduct was revolting.

Channel 10 has obtained images and videos filmed inside parliament involving four coalition staff members.

"Amongst a small number, there is clearly a disgusting and unacceptable culture, and we have to weed it out," Senator Birmingham told the ABC on Tuesday.

"One employee was dismissed last night, and if others are identified as being engaged in similar activity, they will be dismissed as well."

Prime Minister Scott Morrison has described the actions as "disgusting and sickening".

He has urged anybody with more information to come forward.

"The people who come to work in this building are better than this," Mr Morrison said.

"The actions of these individuals show a staggering disrespect for the people who work in parliament, and for the ideals the parliament is supposed to represent.

"I will have more to say on this and the cultural issues we confront as a parliament in coming days."

Senator Birmingham has contacted the journalist who reported the story and requested the whistleblower help the government identify the three other staffers allegedly involved.

"They've shown a complete disrespect for the member of parliament," he said.

"The disrespect I'm talking about is not just a disrespect to the member of parliament, it's a disrespect to the Australian public, it's a disrespect to every other person they work with in this building."

Minister for Women Marise Payne said the allegations highlighted the need for the independent inquiry into the workplace culture of Parliament House, headed by Sex Discrimination Commissioner Kate Jenkins.

"As a senator for NSW, as a minister in this government, and a human being, it's appalling," she said.

"The degrading nature of those actions, which were shown in the media, is beyond disappointing and reinforces the imperative of the review that the sex discrimination commissioner will carry out."
