At least one coalition staffer involved in a group which shared images of themselves performing sex acts in Parliament House has been sacked.
Ten News reported on Monday a small group of staffers had set up a Facebook Messenger group which enabled them to share images and video of sex acts.
An unidentified whistleblower said at times the acts had been performed on the desks of female MPs.
SBS News understands one of the staffers has been sacked, with others possibly to follow.
It comes after Finance Minister Simon Birmingham called for the immediate sacking of coalition staffers alleged to have shared the images.
Senator Birmingham told an estimates hearing on Monday, after the story went to air, that he was "disgusted and appalled".
"It shows a complete disregard for all our parliamentary democracy stands for," he said.
"It also demonstrates an enormous disrespect for the employing member or senator in relation to those staff and those officers.
"It equally shows a complete contempt for the Australian taxpayers who have paid the wages for such staff and, in my opinion, any individuals who engaged in such activity ought to prepare to pack their bags and leave the building for good."
Senator Birmingham said the staffers should also apologise to their employer and the Australian public.
He said it further demonstrated the need for the inquiry by Sex Discrimination Commissioner Kate Jenkins into parliament's workplace culture.
"I want to see this sort of behaviour stamped out," he said.
Labor senator Tim Ayres responded: "It does beggar belief."
