Ms PLIBERSEK (Sydney) (15:08): My question is to the Prime Minister. I refer to the reported sexual assault of Brittany Higgins. This morning in response to a Senate order the government has confirmed the review by the Prime Minister's former chief of staff into what his office knew is a cabinet process. Why is the Prime Minister continuing his cover-up using cabinet-in-confidence? Don't the parliament, the public and, most of all, Brittany Higgins deserve the truth?
