Ms Higgins also took aim at Prime Minister Scott Morrison and singled out senior parliamentary staffers in her statement.
"The continued victim-blaming rhetoric by the Prime Minister is personally very distressing to me and countless other survivors," she wrote.
"A current senior staffer to the Prime Minister and my former Chief-of-Staff refused to provide me with access to the CCTV footage from that evening and continually made me feel as if my ongoing employment would be jeopardised if I proceeded any further with the matter.
"The Government has questions to answer for their own conduct."

Mr Morrison said yesterday two reviews would be undertaken into how parliamentary staff could be better protected.
He said he would be working with Cabinet Deputy Secretary Stephanie Foster to review the processes for workplace allegations and establish an automatic reporting process for department officials.
Mr Morrison said his office was not told about the allegations until a few weeks ago because of the alleged victim's privacy.
"I understand that there was a judgement made about the balance of protecting Brittany's privacy at the time," he said.
"That judgement can certainly be commentated on and be judged, but that was my understanding of what occurred at that time.
