The future of democracy? With Jon Sopel, Nick Bryant and Rosalind Dixon
1w ago00:58:28Tap to summarizeIt 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 AmericaNick Bryant (co-host)Host, Saturday Extra, ABC Radio NationalAuthor, The Forever War: America's Unending Conflict with Itself and moreFormer BBC Washington CorrespondentRosalind DixonProfessor of Law, University of New South WalesFounder, Resilient Democracy LabAuthor, A People's Guide to the Australian Constitution

1w ago00:54:40Tap to summarizeThe 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 FestivalSpeakersProfessor 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 MulticulturalismDr Alexandra DelliosSenior Lecturer, Centre for Heritage & Museum Studies, Australian National UniversityAndrew JakubowiczEmeritus Professor of Sociology at the University of Technology SydneyDr Helen Vatsikopoulos (host)Journalist, academic and Director of the Greek Australian Writers Festival

1w ago00:54:33Tap to summarizeTwo 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:Tony AbbottAuthor Australia: A history and moreAustralian Prime Minister 2013 to 2015President, Australian Liberal PartyMark McKennaAuthor, The Shortest History of Australia and moreProfessor of History at the University of New South WalesSally Warhaft (host)Anthropologist, writer and broadcasterEditor, Well May We Say…The Speeches That Made AustraliaFurther information:The Australian Wars with Rachel Perkins and Henry Reynolds — a watershed event at the Australia War MemorialBig Ideas, ABC Radio National, 4 February 2026Who can we become?

Zoe Daniel with Thom Woodroofe on winning middle Australia in the climate wars
2w ago00:53:57Tap to summarizeHas 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.Speakers:Thom WoodroofeSenior International Fellow, Smart Energy CouncilAuthor, Power, Prosperity & Planet: Climate & Energy Policy for All (In the National Interest, Monash University Publishing)Principal Advisor to Kevin Rudd during his tenure as Australian Ambassador to the United States, and Chief of Staff during his tenure as the Asia Society's President in New YorkDiplomatic adviser to the Marshall Islands in the negotiations of the 2015 Paris Agreement on climate changeZoe DanielFormer Independent Member for GoldsteinFormer ABC journalist and foreign correspondentIndependent chair, Mental Health Victoria

2w ago00:54:34Tap to summarizeWhat'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.SpeakersCheng LeiAuthor, Cheng Lei: A Memoir of FreedomJournalist and Sky News presenterCharlotte GrieveInvestigative journalist, ABC Investigations Unit.Former journalist with Nine mediaAuthor, Duty to Warn: Dr Munjed Al Muderis promised hope.

2w ago00:55:16Tap to summarizeDonor-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.Presented by Sydney Opera House at the All About Women Festival 2026SpeakersAlisha BurnsFounder of Solo Mum Society, host of the No Need for Prince Charming podcast, author of the children's book My Perfect FamilyMaeve MarsdenWriter, Creative Director of Varuna, the National Writers' House, and the Blue Mountains Writers' FestivalDr Melanie SawardBigambul and Wakka Wakka woman, writer, editor and lecturer of Australian Studies, University of QueenslandEdwina Storie (host)Journalist and the lead for The Feed, SBS's youth media brand

3w ago00:53:30Tap to summarizeJoin 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.SpeakersBruce PascoeAuthor, poet, Aboriginal farmer based on Yuin CountryAuthor of Dark Emu and coauthor, Big Sky: When the Emu Left the Earth (Magabala Books, 2006)Professor Ray NorrisAstrophysicist and honorary fellow at CSIROCoauthor, Big Sky: When the Emu Left the Earth (Magabala Books, 2006)Thanks to Dr Tanya Hill, Senior Curator of Astronomy at the Scienceworks, and Veronica Sullivan, CEO and Director of the Melbourne Writers Festival.
