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.

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.

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.

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.
