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.)
