Lecture 5: Challengers

2025 ABC Boyer Lecture Series: Australia: A Radical Experiment in Democracy

Curated and hosted by respected journalist, author and broadcaster, Dr Julia Baird, this year's Boyer Lecture Series explores the theme Australia: A Radical Experiment in Democracy, through five distinct orations examining the strengths and challenges of our democracy as we navigate unprecedented global changes in politics, society and technology.

The speakers—drawn from academia, literature, and policy— reflect on the paradox of Australians' declining trust in politicians alongside their continued faith in the integrity of electoral processes.

This year's keynote is Justin Wolfers, Professor of Economics and Public Policy from the University of Michigan and visiting professor at the University of NSW, whose lecture "Australia is Freaking Amazing", is enthusiastic about our strong institutions and asks whether Australia needs a form of conservative radicalism?

The second lecturer is the Hon John Anderson, AO, farmer, grazier and former deputy prime minister, whose talk, 'Our Civilisational Moment' argues that Australia lacks the spirit, not the machinery of democracy.

Our third lecturer is Larissa Behrendt, a Euahleyai/Gamillaroi woman, Distinguished Professor of Law at the University of Technology, Sydney, and host of the ABC Radio National's Speaking Out program. Her lecture, 'Justice, Ideas and Inclusion' outlines the strengths and pitfalls of our country's legal system, and how our democracy might be enriched by our First Nations' peoples' wisdom of interdependence.

Amelia Lester, a deputy editor at Foreign Policy magazine, our fourth lecturer, examines how Artificial Intelligence could potentially undermine democracy here, in her lecture entitled 'AI, On Australia's Terms'.

And in the final lecture, James Curran, author and professor of modern history at the University of Sydney, will argue that the US Presidency holds advantages for Australia, if we are brave enough to take them, and to confront possible changes in our historic alliance, in his speech, 'Trump's Gift'.

The keynote lecture will be broadcast on October 18 on ABC-TV and on consecutive Sundays starting October 19 on ABC Radio National's Sunday Extra program, at 8.05am.
