Big Ideas

Jack Toohey was flying high. Then he crashed. But from despair came renewal, and a rebellious hope. In 2023, when his social media post about housing affordability attracted over 20 million views — he knew he was onto something. He joins BIG IDEAS host Natasha Mitchell at the Make Good Festival at Bundanon, NSW to talk about the big ideas in his new book Better Things Are Possible: How Rebellious Hope Can Change the World. He wants to help you stop doomscrolling and reclaim the possibilities for creating a more just world.

The ocean calms us. It terrifies us. It heals us. Sometimes all at once. We explore the sea's complex hold on your mental health — from the fear of shark attacks and the medicine of a morning swim to how immersive ocean soundscapes work on the nervous system and ocean grief as part of climate change anxiety.

We are seeing seismic shifts in our politics, as more people than ever turn away from the major parties. Could public policy failures be to blame? Former politician Dr Susan Close has spent her career in the engine room of democracy, and she believes this trend has been caused by successive government policies that have left people behind, created winners and losers and segregated our community — especially in the way Australia funds its schools.
The 2026 Hugh Stretton Oration was recorded at the University of Adelaide on 2 June 2026.

Palestinians and Israelis are building common ground for peace where most say there is none. Since October 7 and the war in Gaza, the idea of cross-community dialogue seems impossible. But behind the headlines, more than 550 leaders from both communities, across politics, security, business, media, and civil society have come together to shape a peaceful future - for both peoples.
What does a just and peaceful solution actually require? Who is doing the work to get there? And is there a role for Australia to play?

When writer Hiroko Yoda's mother died, she found herself unmoored. They'd argued a fair bit over the years — as daughters and their mothers can — some things were unresolved. So now what? She found herself setting off an odyssey to understand Japan's surprisingly flexible, practical, pluralistic approach to spirituality, its infinite number of spiritual beings, its affection for angry ghosts, and the curious possibility of embracing belief and non-belief at the same time. She poured it all into a beautiful book called 8 Million Ways to Happiness. Yes, 8 Million! How can that be!? Find out in this poignant conversation she shares with Big Ideas host Natasha Mitchell on peace, grief, meaning, and overcoming the mountains within.
This event was recorded live at the 2026 Melbourne Writers Festival. To explore more of the festival's events and talks, visit mwf.com.au.
