Senator WATERS (Queensland—Leader of the Australian Greens in the Senate) (14:25): This building is a high-risk workplace. Ms Brittany Higgins said, of the sight of the Prime Minister standing next to Young Australian of the Year Grace Tame, herself a survivor of sexual assault: He's standing next to a woman who has campaigned for 'Let Her Speak' and yet in my mind his government was complicit in silencing me. It was a betrayal. It was a lie. Would you support requesting the Sex Discrimination Commissioner to undertake a culture review of Parliament House to recommend ways of keeping staff safe?
