Populate or Perish: How Post-War Migration Remade the Nation
🎯 Today's mission briefing
We are learning how the post-1945 immigration program transformed Australian society, economy and identity — including the assimilation policy, the resistance the program met at the time, and the contested road from assimilation to multiculturalism.
You'll know you've got it when:
- I can explain the strategic and economic drivers of the post-war immigration program and sequence its phases with dates, from 1945 to the 1970s and beyond
- I can analyse the shift from assimilation to integration to multiculturalism as a policy sequence, naming the legislation and reports that mark each turn
- I can evaluate evidence of resistance to the program — at reception centres, in workplaces and in public debate — and hold both truths: a nation genuinely remade, and a change contested at every stage
Seven and a half million people, and a very short deadline

In 1945 Australia had roughly seven and a half million people, a continent-sized coastline, and a government that had just spent four years watching how quickly the region could turn dangerous. The new Minister for Immigration, Arthur Calwell, put the case in two words that stuck to the whole era: populate or perish. What followed was one of the largest per-capita migration programs any nation has ever run — millions of arrivals across three decades, from Britain, then Europe's displaced-persons camps, then southern Europe, then, after 1975, Asia. Here is the senior-level question, and it is not a comfortable one: a program of that size does not happen without a policy telling arrivals what they must become. What did Australia demand of the people it recruited, who objected, and how did the demand change? Today you audit a national transformation — the achievement and the friction, with dates attached to both.
