    What Transformative AI Could Mean for Australia — Danielle Wood

    Danielle Wood is an Australian economist and the current chair of the Australian Productivity Commission. Had a lot of fun chatting with Dani about how she's making sense of AI and its implications for policy. We discuss: whether AI will be more like the internet or the Industrial Revolution, where in the AI stack the profits will ultimately flow (and why it might not be the model layer), why diffusion is the "main game" for Australian policymakers, whether there's a case for government support of data centres, why the AI jobpocalypse story is too crude (and why humans may still have jobs even under transformative AI), whether AI will turn out to be a normal or abnormal technology, or both, and why in either case Australia shouldn't follow the EU in legislating an AI Act.

  2. How Australia Actually Selects and Integrates Migrants — Mike Pezzullo [Immigration Series]

    How Australia Actually Selects and Integrates Migrants — Mike Pezzullo [Immigration Series]

    Part 3 of a three-part immigration series this week. Martin Parkinson (economics) available here; Mark Cully (history) available here. Mike Pezzullo ran the Australian Customs and Border Protection Service (2013-2014), then the Department of Immigration and Border Protection (2014-2017), then the Department of Home Affairs (2017-2023). For more than a decade across those three roles, he was responsible for how Australia selects migrants, screens for risk, and thinks about social cohesion under stress. We discuss the central but underappreciated fact about how Australia selects migrants: the diversity of our intake is a happy accident of global migration flows, not engineered policy. We also walk through how the visa system actually screens for security and character, why Pezzullo doubts the Bondi terrorist's father would have been refused a student visa in 1998 even with today's tools, what a 2027 China-Taiwan blockade would mean for the Australian migration system in real time, and a never-aired proposal for fixing Australia's "permanent temporaries" problem — a constitutional amendment Pezzullo calls "the Pezzullo special." We finish with: should "populate or perish" return as defence policy?  (Episode recorded on 16 March 2026.)

    "Bigger and Different": The Six Decades That Remade Australia — Mark Cully [Immigration Series]

    Part 2 of a three-part immigration series this week. Martin Parkinson (economics) available here; Mike Pezzullo (acculturation, social cohesion, security) drops Friday. Mark Cully was the inaugural chief economist at the Australian Department of Immigration (2009-2012). His forthcoming book, Waves of Plenty (September 2026), is (to my knowledge) the first truly general history of immigration to Australia. It will fill a remarkable gap in our literature, given the centrality of immigration to the Australian story. We discuss Australian exceptionalism in migration policy. The only country to have run assisted passage at scale (around 3.5 million people whose fares were subsidised). The first country in the world to have a dedicated Department of Immigration. The first country to offer migrants English-language training. Per capita, the world's largest receiver of international students for decades. Today, one of only three countries – alongside Switzerland and Singapore – with an overseas-born share above 30%. On current trends that share is projected to approach 40% by mid-century, a level likely not seen since the 1880s. We walk through six decades that built the nation – the 1830s, 1850s, 1890s, 1950s, 1970s, and 2000s. We discuss why Australia eschewed slavery, why the 1850s might be the most important decade in the making of modern Australia, and what the White Australia policy was really about. We also explore what made the post-war migration program the most epic policy experiment in our history, whether migration has increased Australian living standards, and what history can teach us about the rise of One Nation.

  4. "We've built an economy that requires 2 million temporary migrants" — Martin Parkinson [Immigration Series]

    "We've built an economy that requires 2 million temporary migrants" — Martin Parkinson [Immigration Series]

    Part 1 of a three-part immigration series this week. Mark Cully (history) drops Thursday; Mike Pezzullo (acculturation, social cohesion, security) drops Friday.  Martin Parkinson ran the Australian Treasury (2011-2014), then the Department of Prime Minister & Cabinet (2015-2019). He's also thought deeply about the economics of migration policy, not just in those roles, but also in his past academic life and as chair of the Australian government's 2023 Migration Review (the most significant review of our migration system in more than three decades). We discuss the central but underappreciated issue with Australian migration policy today: we've drifted into a quasi-guest-worker system without anyone voting for it. About 2.3 million people in Australia now go to sleep here every night with work rights, but without being citizens or permanent residents. We also work through how migration affects living standards, the "Soviet-style" occupation list that governs our skilled program, how to attract true global talent, how international student fees came to subsidise roughly half of Australian university research, and what should be the upper and lower bounds for net migration. We end up in an unexpected place: how much more geopolitical weight would a larger population actually buy us? (Episode recorded on 27 February 2026.)

  6. Cabinet is Australia's Operating System — Here's How It Works (Glyn Davis & Terry Moran)

    12/22/2025

    Cabinet is Australia's Operating System — Here's How It Works (Glyn Davis & Terry Moran)

    Glyn Davis and Terry Moran are two of the very small number of Australians who have literally sat in the Cabinet Room, week after week, watching the machinery of government operate from the inside. Both served as Secretary of the Department of the Prime Minister and Cabinet (PM&C) — the most senior public servant in Australia. Terry held the role from 2008 to 2011 (including during the Global Financial Crisis). Glyn held it from 2022 to 2025. Both have also held equivalent roles at the state level: Glyn as Director-General of the Office of the Cabinet in Queensland (1995–96), and Terry as Secretary of the Victorian Department of Premier and Cabinet (2000–08). Before PM&C, Glyn was Vice-Chancellor of the University of Melbourne for thirteen years, and later ran the Paul Ramsay Foundation (Australia’s largest philanthropic foundation). Terry’s career spanned senior roles across the Commonwealth and Victorian public services, including as CEO of Victoria’s Office of the State Training Board, inaugural CEO of the Australian National Training Authority, and Queensland’s Director-General of Education. He later served as Chancellor of Federation University. In this episode, we trace the routines, conventions, and systems that shape power in Canberra. Where, exactly, does a prime minister’s power come from? What separates a good Cabinet submission from a bad one? What actually happens in the Cabinet room once the doors close? How does Australia’s Westminster model differ from the UK and Canada? And why is Australia so unusually good at bureaucracy? (Episode recorded on 8 December 2025.)

  7. Why Great Powers Sleepwalk to War — A Masterclass with Prof. Hugh White

    Why Great Powers Sleepwalk to War — A Masterclass with Prof. Hugh White

    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.

  8. Australia's last great act of economic courage — Peter Costello

    11/02/2025

    Australia's last great act of economic courage — Peter Costello

    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.   Episode sponsor: Vanta: helps businesses automate security and compliance needs.
