  • The future of democracy? With Jon Sopel, Nick Bryant and Rosalind Dixon

    It may be the least worst form of government, but faith in its leaders and its institutions is waning. From the US to the UK to Australia, democracy has also paradoxically delivered representatives who are proudly anti-democratic and openly undermine democratic institutions like electoral systems, the judiciary and a free media. So why do people see the likes of Donald Trump, Nigel Farage, and Pauline Hanson as the answer?

    The Future of Democracy was recorded at the 2026 Sydney Writers Festival in partnership with the Resilient Democracy Lab at the University of New South Wales.

    Speakers:

    Jon SopelCo-host The News AgentsAuthor, Strangeland: How Britain Stopped Making Sense, UnPresidented: Politics, Pandemics and the Race that Trumped All Others and moreFormer editor, BBC North America

  • Can Art, artists and activists save Australia’s famous multicultural experiment?

    The fabric of multicultural Australia is under a kind of pressure it hasn't faced in a long time. Can it be renewed? And what role do artists, activists, and migrants have to shape what comes next? The landmark work The Elgar Companion to the Arts and Global Multiculturalism is asking exactly those questions. It traces multiculturalism from its origins as a political philosophy and as lived cultural practice right through to the complicated present. And it makes a case that the arts have been central to this story all along. 

    Presented at the Greek Australian Writers Festival

    Speakers

    Professor Nikos PapastergiadisDirector of the Research Unit in Public Cultures at the University of Melbourne Co-editor of the book The Elgar Companion to the Arts and Global Multiculturalism

  • Pride or shame? Searching for the story of Australia — with Tony Abbott, Mark McKenna and Sally Warhaft

    Two authors. Two books. Two very different histories of Australia. Tony Abbott's Australia: A history and Mark McKenna's The Shortest History of Australia were released within weeks of each other. They share similar references, but diverge in key areas, especially when it comes to how the country should reconcile with its Indigenous past. So what is the real story of Australia?

    The conversation Australian history's great divide: how writers view our past was recorded at the Sorrento Writers Festival on 23 April 2026.

    Speakers:

  • Zoe Daniel with Thom Woodroofe on winning middle Australia in the climate wars

    Has the Iran War got you thinking about changing to an electric vehicle? Did government subsidies help you go solar or install a home battery? When renewable energy makes good economic sense, and eases cost of living pressures, people want in. As the public's desire for action on climate change is eclipsed by other concerns, and beset by vested interests and mis and dis information, how does climate policy win back ordinary people to galvanise progress once again?

    This event was recorded at Readings bookshop on 20 May 2026.

  • 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.

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

    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

    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?

    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.
