When former coalition staffer Brittany Higgins came forward to allege that she had been raped in a ministerial office in Parliament House, it horrified the country. Her account of effectively being silenced for political reasons sparked outrage and condemnation of the culture of Canberra. Four Corners investigates how and why Brittany Higgins’ story was kept quiet for almost two years. The program examines the key questions of who knew what, and when, and whether there’s been a cover up.
