Three Shocks: Who We Are Becoming in the 21st Century

by George Megalogenis

For decades our politics has failed to keep up with a changing Australia. The federal elections of 2022 and 2025 were an overdue wake-up call to three shocks that have reshaped our national

– For the first time since federation, we have a population that’s majority migrants and their children
– Professional women are now the largest segment of the workforce, replacing blue-collar men
– On the world stage, both our allies and our key trade partners have proven unreliable

Together, these shocks have changed the electoral maths for our politicians. For too long both major parties operated on outdated assumptions about Australia that go back to the Howard era.

With original interviews and research, Three Shocks tells the inside story of how our politicians caught up to the times or were left behind. Labor learned how to win again by embracing our new diversity; the Liberals suffered back-to-back landslide defeats that have threatened their very existence.

These three shocks will define our national politics in the future, but they should change how we all think about Australia and who we are becoming in the twenty-first century.

Reviews

[Elijah Freeman]

This is the third in Megalogenis' trilogy of Australian political histories. I read the first two as a high school student and then as a political science student and really appreciated the way that they take a macro view of Australian politics to tell a broad story of Australian politics. This third book is a really welcome analysis of the Abbott-Turnbull-Morrison and Albanese governments. There have been so many small developments in Aussie politics in the last decade that felt huge at the time but are now largely forgotten. The strength of the book is that it picks up those moments and shows how they were actually illustrative of broader demographic changes. It also treats the Howard and Rudd-Gillard governments as part of the same story as our more recent ones, tracing the origins of today's politics to the late 90s and early 00s.

The two framing devices - the tree of Australian demographics and the idea of three shocks that inform Australian politics today - are simple. I've heard them critiqued (generally validly) in the media the last few weeks, but that doesn't mean that they aren't useful ways to think about Australia today. I also wish that Queensland got a bit more attention, but that would go against Megalogenis' central point that the locus of political power in Australia has moved away from my home state to the southern capitals.

I've been avoiding reading non-fiction this year, but I was happy to make the exception for this one. 4/5

This was a great book until it got to the Covid section where the info is straight up either wrong, misremembered or polished poo.
