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

    10/06/2026 | 54 mins.
    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.

    Sperm shortages, shady Facebook groups, and other intimate stories of modern donor conception

    08/06/2026 | 55 mins.
    Donor-sperm conception has become even more difficult in Australia. Would-be parents are now facing a shortage of sperm. That's on top of an already complex end confusing process. For solo parents, queer couples, and people navigating fertility the path to parenthood often begins with long clinic waitlists, overseas donor profiles, shady Facebook groups or delicate conversations with friends.

    How can we design our way out of Australia's housing crisis? With Anthony Burke and Tim Ross

    04/06/2026 | 58 mins.
    From embracing the future of new technologies, materials and innovations, to returning to past times of multigenerational and communal living, architecture and design has plenty to offer when it comes to solving Australia's housing crisis. While debate rages about tax settings, government policy, and urban planning, design solutions are there to create the homes, the communities and the lives we need to make us happier and healthier — but is the will?

    Dark Emu's Bruce Pascoe and astrophysicist Ray Norris — can Aboriginal astronomy unite humanity under one big sky?

    03/06/2026 | 53 mins.
    Join Bruce Pascoe and Professor Ray Norris with Natasha Mitchell to discuss their eye-opening new book Big Sky: When the Emu Left the Earth. Then go outside, look up, and wonder about what connects humans rather than divides us. Humans have always gazed at the night sky, and (when we could) into the far reaches of our galaxy, to make meaning and sense of life here on Earth. The stories we tell about stars, planets, the Sun, the Moon, and more offer powerful lessons for us all — and for our relationships.
    This event was hosted by the Melbourne Writers Festival (find out more at mwf.com.au), Scienceworks, Bunjilaka Aboriginal Cultural Centre on the country of the Bunurong people of the Kulin Nation and the Bunurong Land Council Aboriginal Corporation.
