Federal police have in the last three months received 40 reports about 19 allegations of sexual misconduct linked to federal politicians and staff.
Australian Federal Police Commissioner Reece Kershaw wrote to MPs and senators in February about the need to report crimes after former Liberal staffer Brittany Higgins went public with rape allegations.
At a Senate estimates hearing in Canberra on Tuesday, Mr Kershaw said the letter resulted in 40 reports about sexual misconduct linked to politics.
A dozen of the reports have been marked as sensitive investigations, while a further 10 have been referred to state or territory police.
The AFP has finalised its investigation into one matter, while another is the subject of ongoing inquiries.
Mr Kershaw said seven did not relate to electorate officers, ministerial staff or official establishments.
Officers were unable to say how many were about incidents that happened within Parliament House.
Ms Higgins says she was raped by a colleague in a minister's office while employed as a staffer in March 2019.
After investigating the allegations, ACT police are expected to refer a brief of evidence to prosecutors within weeks.
