Duty to warn — when challenging power becomes personal, and why journalists Cheng Lei and Charlotte Grieve didn't give up

What's the toll when your story becomes the story? What these journalists endured for their work beggars belief, but it hasn't stopped them believing in the role of journalism to hold power to account. Locked in a Chinese jail under 24/7 surveillance for more than 3 years — Cheng Lei is now determined to speak out about freedom and the long tendrils of Chinese state control because others can't or won't. Charlotte Grieve's investigation of a superstar surgeon and his patients' horrifying experiences was subject to one of the longest defamation trials in Australian history — a major test case for the public interest defence. Hear their extraordinary stories. They join Big Ideas host Natasha Mitchell at this Sorrento Writers Festival event. Speakers Cheng Lei Author, Cheng Lei: A Memoir of Freedom Journalist and Sky News presenter Charlotte Grieve Investigative journalist, ABC Investigations Unit.
