It comes as the Morrison government continues to grapple with mounting allegations - from rapes to misconduct - from within the walls of Parliament House.

Prime Minister Scott Morrison and his government have been under increasing pressure to take action after former Liberal staffer Brittany Higgins spoke out about allegedly being raped by a former colleague in Parliament House in 2019.

It has triggered a wave of revelations from women about harassment, assault and sexism in workplaces and the community and sparked a national protest movement calling for more action.

While most allegations involving parliament have involved coalition MPs and their staff, workplace sexual harassment allegations have also been raised from within the Labor Party.

Further allegations surrounding Parliament House were aired on Channel 10 on Monday night. The broadcaster aired a story after receiving lewd images and videos filmed inside Parliament House involving four coalition staff members.

One, who filmed himself performing a sex act on a federal Liberal MP's desk, was dismissed on Monday night.

Federal Labor MP Catherine King, the member for Ballarat, said the allegations pointed to disrespect of women and the need for cultural change within the nation's Parliament.

Asked about the behaviour aired on Channel 10 - which also included allegations politicians had brought sex workers into the building- Ms King said it was completely "unacceptable"

"None of it is acceptable behaviour within any workplace let alone the nation's Parliament.

"It is clear from the alleged rapes to the incidences aired on Channel 10 last night to many of the stories that are coming forward from women that this has not been a place where women have been as respected as they should be," Ms King said.

"I think it's incredibly important that every person is safe in their workplace, including in this place."

Ms King, who has been a member of parliament for 20 years, has recently made headlines for repeatedly pressing Mr Morrison for answers about whether his office backgrounded against Brittany Higgins's family and friends. With the question asked 12 times to date, she is yet to receive an answer.

Ms King said the new allegations about coalition staff members, including that of the staff member who has been dismissed, were "disgusting".

"Speaking for many of the people here who know who that person was, they are shocked and feel really violated in some way that this was a work colleague who believed that this was okay.

"It shows an absolute contempt of women and absolute disrespect for women and their boss. It is in and of itself appalling but also speaks to a broader problem.

"These things don't happen in an environment where women are respected and treated as equals".

Ms King said the mounting allegations about conduct within the walls of Parliament House highlighted a need for a cultural shift.

"I think that speaks again to that if that is the culture that allows something like that to occur, then what else has been happening that we don't know about?

"I think it's really about culture and about power."

Ms King said there was a lot of work to be done to better protect and support women at work, but there was also "really significant work to do to change the culture".

In a media conference on Tuesday, Prime Minister Scott Morrison pledged to "get our house in order" after weeks of pressure.

One week after refusing to meet thousands of women protesting outside Parliament House, the Prime Minister admitted some of his responses had fallen short.

"I acknowledge that there have been people who haven't been happy with how I have responded in every single way over the course of this last month," Mr Morrison said.

He admitted his responses to the furore around the treatment of women in Australia had fallen short.

"These events have triggered, right across this building and indeed right across the country, women who have put up with this rubbish and this crap for their entire lives, as their mothers did, as their grandmothers did," he said.

"We must get our house in order," Mr Morrison said.

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