Sky News host Peta Credlin says gay "orgies" were happening in Parliament House offices during her time as former prime minister Tony Abbott's chief of staff.
It is the latest in a long line of inappropriate behaviour and sexual abuse claims that have rocked Canberra in recent weeks after former cabinet staffer Brittany Higgins went public saying she was raped inside Parliament House in 2019.
Speaking on her Sky News show on Wednesday, she said the historical orgies, which involved Liberal and Labor staffers, took place while MPs were in Question Time.
She also said the man sacked for his involvement in a series of lewd sex acts documented in images and video leaked to Channel 10 this week was previously dismissed under her instruction.
"He was someone I sacked many years earlier [and] he never forgave me for it," she said.
Credlin said he had branded her a "bitch" for the move where she vowed he would never return to Parliament House while she was there.
However, as Malcolm Turnbull became prime minister, she said the man returned.
Credlin said she also knew the three other men involved in the scandal.
"I see you," she said, as she pointed to her eyes and then to the camera.
Finance Minister Simon Birmingham declared earlier this week that if the others involved were identified, they would likely be fired.
"As a woman, boy I made some enemies. I have never publicly spoken about my side before," Credlin continued.
“But I am not going to stay silent anymore."
Prime Minister Scott Morrison on Tuesday slammed the behaviour as "absolutely shameful".
He also vowed to do more to improve working conditions for women in Canberra and nationwide.
"I want women to have at least the same opportunities and the same voice and the same safety as men in this country," he declared.
"We must get this house in order."
However he caused controversy for levelling a false sexual assault allegation in a News Corp office, which he later apologised for.
"I was wrong to raise it," he said in an address late on Tuesday.
NSW Nationals MP accused of rape
Women across Australia continue to raise reports of inappropriate behaviour with links to politics.
By Thursday morning, parliaments in NSW, Queensland, Tasmania and Canberra had each been told of allegations of rape, groping, harassment and slut shaming.
A woman sex worker was allegedly raped by a male MP in the Blue Mountains, NSW Labor MP Trish Doyle told state parliament in shock revelations late on Wednesday.
"It is all the worse that this man who raped her is a government member of this chamber," she said, speaking under the protection of parliamentary privilege.
Hours later Nationals MP Michael Johnsen announced himself as the accused and strongly denied the claims. He resigned from his role as parliamentary secretary and advised he was taking immediate leave from parliament.
"I have voluntarily spoken with NSW Police and I have and will continue to fully cooperate with their inquiries," he said in a statement.
"I am confident any investigation will conclude that I am an innocent party."
More allegations arise from Tasmania and Queensland
Earlier in the day Tasmania's lower house heard from Speaker Sue Hickey, who accused Liberal Senator Eric Abetz of slut shaming former federal staffer Brittany Higgins by saying she was "so disgustingly drunk" she "would sleep with anybody".
Senator Abetz denies the allegation.
Ms Higgins has reported to police that she was raped in federal parliament house by another Liberal staffer in 2019.
In Queensland parliament on Wednesday, Health Minister Yvette D'Ath said that when she was attorney-general two years ago she was groped by a visiting dignitary during a meeting at parliament.
Her revelation follows recent accounts from fellow Queensland Labor MP Jonty Bush of having been subject to sexual abuse and harassment, spanning years.
