Shruti Rajagopalan —  On Spotting Talent, And Making Sense of Rising India

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.

How Can Australia Get a Piece of the AI Action? — Danielle Wood

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?

How Australia Actually Selects and Integrates Migrants — Mike Pezzullo [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.
