Senator BIRMINGHAM (South Australia—Leader of the Opposition in the Senate) (14:00): My question is to the Minister representing the Prime Minister, Senator Wong. I refer the minister to the column written by former Labor state secretary and former Labor chief of staff Cameron Milner in the Australian today marking the anniversary of the tragic death of our former colleague Kimberley Kitching. Is Mr Milner correct that there still has not been an investigation into allegations of workplace bullying? Honourable senators interjecting— The PRESIDENT: I'm going to ask for order and I expect there to be order.
