Big Ideas

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.

Stories help us to understand what is happening in the world and how it impacts us. Stories help us to relate to the experience of 'the Other' and their suffering building an emotional understanding. Journalist and academic Helen Vatiskopoulos describes the power of stories to share information to the masses and the problems that arise when the narrative is distorted. What is the responsibility of the media? How does media and social media impact on whose stories are being told and whose are being left out?

For 85 years, Meanjin has published the essays of Australian writers.

It's water and fireproof, versatile, warm and tough wearing. Wool not only expanded the British Empire, and created prosperity in the colonies, it also changed the nature of war and warfare. But wool's fortunes didn't last forever. This is the story of the rise and fall of wool.

Has your doctor ever told you to go on a diet? Does that conversation put you off going to them in the first place, even if you need treatment for something not related to your weight? Has being in a larger body ever meant you can't access surgery or IVF? Some are pushing for a weight-inclusive approach to healthcare, which de-centres obesity, and focuses on 'health-at-every-size'. But what does that really mean, and why does it matter?

This event was held at the 11th Annual Weight Stigma Conference at Griffith University.

Meet two men on a lifelong mission. They've ruffled a lot of feathers along the way. Some revere them, others revile them. John Wamsley set up Australia's first wildlife sanctuary, but he's perhaps best known as the "cat-hat-man" (sorry, cat lovers!). World renowned forest ecologist David Lindenmeyer has copped heat from Australia's forestry industry for his science. But these two trailblazing environmentalists aren't afraid of their critics - to them it's a case of life-or-death for Australia's extraordinary species. Join them with oral historian Greg Borschmann as part of his Heartlands Conversations series presented at the Blue Mountains Music Festival.
