Big Ideas

If a stiff dose of medical misinformation is what you're after, look no further than the White House right now. And, on social media and in online forums, countless conspiracy theories reign supreme. In this "post-truth" era, has science lost its authority, or have we lost sight of what scientific proof actually involves? From debates over the origins of our species to conspiracies surrounding the origins of COVID19, Dr Elizabeth Finkel goes where others fear to tread to lift the lid on how science works. Join her with Big Ideas' host Natasha Mitchell at this event hosted by the Royal Society of Victoria and Black Inc Books.

The Beatles shook the world to its core in the 1960's and, to this day, new generations continue to fall in love with their songs and their story. At the heart of this phenomenon lies the dynamic between John Lennon and Paul McCartney. Few other musical partnerships have been rooted in such a deep, intense and complicated personal relationship. Ian Leslie uses the songs they wrote to trace the shared journey of these two compelling men before, during, and after The Beatles.

This talk is provided by the York Festival of Ideas. The Festival is led by the University of York, UK

The world feels more dangerous and unpredictable, but with Australia wedged between our traditional ally, America, and our biggest trading partner, China, does our most expensive ever defence project make us more secure, or less?

A frank and impassioned plea for peace by Gareth Evans. As Australia's former Foreign Minister and former president of the International Crisis Group, he's spent most of his career forging real paths to peace globally. From Sudan to Gaza, Myanmar to Ukraine - who can we rely on to stop "forever" wars and genocides? Does Australia have a unique role to play? And what about the UN in its 80th year? It was created after the horror of World War 2 to keep the peace. Has it lost its way? The 2025 Brisbane Peace Lecture is presented by the United Nations Association of Australia, Brisbane - and includes responses by two key leaders from the Sudanese and Palestinian communities.

Primatologist Jane Goodall once said: "It actually doesn't take much to be a difficult woman. That's why there are so many of us." She spoke up. For all the species who go unheard, or unnoticed by humans. She was a giant in the global environmental movement. She first walked into the wild forests of Tanzania as a young woman with no science training and embarked on what is now the longest-running study of chimpanzees in their natural habitat. Her trailblazing fieldwork changed our understanding of other primates and the threat we pose to their continuing existence. It changed her. And it changed the world. At 91, she was still travelling the world right up until her last breath, to help give all other species theirs. She was deeply compassionate, and her campaigns deeply connected with people. Dr Jane Goodall joined Big Ideas host Natasha Mitchell to discuss hope in action the 2022 WOMADelaide Festival. This conversation was originally broadcast on ABC Radio National's Science Friction in May 2022.

AI is an incredible tool, but is AI also a new coloniser? Is there actually anything new or artificial about artificial intelligence?

Is AI the new coloniser? How to create more life-centred AI before it's too late

Former US secretary of state Condoleezza Rice assesses the break-up of globalisation and the world order. The way in which countries such as the United States or Germany focus on sovereign goals is part of the problem. And that's likely not to stop any time soon. But she also comes up with practical ideas for creating a common economic and security future to address the issues that are too big for any single nation to tackle alone.

Australian Indigenous art is celebrated around the world – but how much is understood about its pivotal role in Indigenous culture, country, politics and law? 

For the Yolngu people of north-east Arnhem Land, art is more than just aesthetic, it is a means of cultural diplomacy, and a respectful assertion of power in its diverse forms, from sovereignty to influence, authority and control, to energy, strength and pride.

This episode brings together two significant exhibitions of Indigenous art on now, Yolngu Power: the art of Yirrkala, and 65,000 Years: A Short History of Australian Art.

This conversation was recorded at the Art Gallery of New South Wales on 30 July 2025.

A freckle-faced kid from Bondi, Pauline Menczer fought the entrenched sexism of the pro-surfing scene to became women's world surfing champion and pave the way...er, waves..for girl grommets today. But all the while she was also fighting another battle inside her own body’s cells. Ironwoman and surf lifesaving champion Bonnie Hancock became the fastest and youngest person, and the first Australian woman, to circumnavigate Australia on a small surf ski, solo. What possessed her to paddle 12,700 kilometres through crocodile and shark-populated waters, mega-waves, and worse? Pauline and Bonnie join Big Ideas' host Natasha Mitchell for a conversation that might inspire you to chase your dreams, big or small.

This event was organised and hosted by the Queenscliffe Literary Festival.
