Why Great Powers Sleepwalk to War — A Masterclass with Prof. Hugh White Nov 25, 2025

Show notes

2,500 years of strategic history, 11 books, one afternoon.

Hugh White is Australia's foremost strategic thinker: former senior adviser to Defence Minister Kim Beazley and Prime Minister Bob Hawke, Deputy Secretary for Strategy and Intelligence in Defence, inaugural Director of ASPI, and principal author of the 2000 Defence White Paper. He is now Emeritus Professor of Strategic Studies at the Australian National University.

Before this conversation, I asked Hugh for the eleven books that most shaped his thinking on strategy, international relations and defence policy. We work through them one by one — what each book argues, what it gets right and wrong, how it shaped his worldview — and use them to tackle the big questions: why great powers start disastrous wars, how international orders collapse, and how Australia and America should respond to the rise of China.

Australia's last great act of economic courage — Peter Costello Nov 02, 2025

Show notes

Peter Costello is the longest-serving Treasurer of Australia (1996–2007).

He led the most complex overhaul of Australia's tax system in the postwar era: introducing the Goods and Services Tax (GST) — a value-added consumption tax — while abolishing a range of indirect taxes (notably wholesale sales tax) and cutting income-tax rates.

I wanted to learn from Peter what it actually takes to achieve a reform at that scale — and why we haven’t managed anything like it since.

In this conversation, we discuss:

GST implementation war stories;
lessons on how to get big things done in government;
why major reform became so much harder after 2000;
why Peter would sometimes hide revenue estimates even from the prime minister; and
the baby bonus (introduced in 2004), which led to an uptick in Australia's total fertility rate — making Australia one of the only western countries to increase (albeit temporarily) its TFR since the demographic transition began.

The Discovery of The Bacterium Behind 5% of All Cancers — Barry Marshall Aug 26, 2025

Show notes

One bacterium causes roughly 1 in 20 cancer cases worldwide. It’s the most cancer-causing pathogen we’ve found—and the main cause of peptic ulcers. Its discovery overturned an ironclad medical dogma that the stomach was sterile.

Despite infecting about half of humanity, Helicobacter pylori wasn't discovered until 1979 and shown to cause gastritis and peptic ulcer disease in the early 1980s. Why did it evade detection for so long—and what finally broke through the consensus?

I went to Perth, Australia—where H. pylori was first discovered—to chat with Barry Marshall, gastroenterologist and co-recipient (with Robin Warren) of the 2005 Nobel Prize in Physiology or Medicine for discovering H. pylori and proving that it causes gastritis and peptic ulcer disease. Marshall famously infected himself with the bacterium to demonstrate causality and later helped develop clinical diagnostics like the urea breath test, which we demo live in the episode.

We discuss:

the rise and fall of stomach cancer in the West;
whether Darwin’s dyspepsia and Napoleon's stomach cancer trace to H. pylori;
the ulcer–cancer paradox;
Correa’s cascade: what H. pylori eradication reverses—and what it doesn’t;
the “H. pylori enigmas” (Africa, India, Costa Rica);
eradication prospects and an oral vaccine timeline;
how the field missed the discovery;
how the primitive internet enabled the discovery;
what the H. pylori discovery teaches us about how knowledge diffuses;
lessons from manufacturing millions of tests in Perth;
and much, much more.

Australia’s ‘Great Stagnation’: Everything You Need to Know About The Productivity Crisis — Greg Kaplan & Michael Brennan Aug 14, 2025

Show notes

Stagnation! The 2010s witnessed Australia’s weakest productivity growth in six decades.

How much of the slowdown is homegrown? How much reflects the broader “great stagnation” plaguing the West?

How much is simply an artefact of the way “productivity” is measured?

And what would a credible new growth model for Australia—with its distinctive reliance on mining over manufacturing—actually look like?

To answer these questions and more, I’m joined by two of Australia’s smartest economists.

Greg Kaplan is the Alvin H. Baum Professor of Economics at the University of Chicago. He is also the cofounder and chairman of e61, a non-partisan economic economic research institute in Australia.

Michael Brennan is the CEO of e61. He was previously chair of Australia's Productivity Commission and a Deputy Secretary of the Australian Treasury.

We discuss the forces behind falling construction productivity; how to think about “Australia’s most productive company”; where to find quality gains in the services sector; what we can learn from the stunning innovativeness of Australia’s agricultural industry; why we need new economic engines beyond the Sydney–Melbourne duopoly; and much, much more.

Francis Fukuyama — AGI and the Recommencement of History Jul 31, 2025

Show notes

Francis Fukuyama is a Stanford political scientist and the author of (among many other works) The End of History and the Last Man—arguably the most influential work in political science of the past half-century.

If “History” is driven by technology, how does Fukuyama now view biotech and AI—and their potential to usher in a new, post-human history?

These are difficult questions, but I wanted to ask Frank about topics that are both important and (at least for AI) on which he has spoken little until now.

We also get a sneak peek at his forthcoming book and discuss his ideas on bureaucracies, delegation, and state capacity.

Laura Deming — On Pausing Biological Time & Preserving the Continuous Self May 20, 2025

Show notes

Laura Deming is a technologist and venture capitalist focused on anti-ageing and life extension. At 17, she founded The Longevity Fund (followed by age1), the first VC firm dedicated to longevity biotech, after being selected in the initial cohort of Thiel fellows (2011). Today she is also CEO and co-founder of Cradle, a startup pursuing human whole-body reversible cryopreservation.

I speak with Laura at Cradle’s San Francisco office. We start with the philosophical question of personal identity, and ask a deceptively simple question: what, exactly, do we want to preserve? From there we explore what a “more humane transhumanism” might look like, the game-theory of 200-year lives, scientific awe as a research tool, embodied thought-experiments to see inside the cell, how the FDA could shave years off longevity-drug timelines, the anti-memetic qualities of reversible cryopreservation, and why it might be the most leveraged problem in longevity.

Show notes

This episode is the seventh instalment of my Australian policy series, recorded live in Sydney on April 29, 2025.

We discuss how AGI could reshape the public service, intergenerational unfairness in the tax system, the collapse in business investment, how to build a new Australian city, and the roots of Australia's long-standing policy complacency.

Sam Roggeveen — Why the US Won't Fight China for Dominance (and What it Means for Australia) [Aus. Policy Series - LIVE] Apr 02, 2025

Show notes

This episode is the sixth instalment of my Australian policy series, recorded live in Sydney on February 26, 2025.

I speak with Sam Roggeveen—Director of the Lowy Institute’s International Security Program, and a former senior analyst at the Office of National Assessments—about why the United States won’t fight China for dominance in Asia, and what that means for an Australia long reliant on American protection.

We explore the limits of America’s resolve in Asia, why an alliance with Indonesia should be the top priority of Australian statecraft, whether new technologies like drones are reversing the long-held advantage of the defender, the possibility that Australia might one day acquire nuclear weapons, and how Sam’s “echidna strategy” could let us defend ourselves from a major Asian power without substantially boosting defence spending.

Peter Tulip — What Will It Actually Take to Solve the Housing Crisis? [Aus. Policy Series - LIVE] Mar 25, 2025

Show notes

This episode is the fifth instalment of my Australian policy series, recorded live in Sydney on February 12, 2025.

I speak with Peter Tulip—Chief Economist at the Centre for Independent Studies, and a former senior researcher at both the Reserve Bank of Australia and the US Federal Reserve.

We go deep into what's driving Australia's housing crisis, the problems with heritage rules and height restrictions, critiques of both NIMBY and YIMBY thinking, the sobering 10–20-year timeframe that even an “extremely ambitious” supply plan might require, and the cultural shift needed to reach a new equilibrium where housing is truly abundant.
