In 1945 Australia and New Zealand still saw themselves as outposts of Britain — mostly white, mostly British in ancestry, and proud of it. By 2020 both were visibly multicultural nations.
That change is one of the biggest stories of continuity and change in this whole regional study.
The trigger was fear. World War II showed Australia how small and exposed it was — Japan had bombed Darwin in 1942, and Britain could not protect it. Immigration Minister Arthur Calwell's slogan afterward was blunt: 'populate or perish.' Australia needed many more people, fast, to build its economy and defend itself.
The White Australia Policy: Since 1901, Australia's White Australia Policy used a dictation test to keep out non-European migrants. After 1945, 'populate or perish' first meant recruiting British migrants, then — when Britain alone couldn't supply enough people — displaced persons and migrants from Italy, Greece, and the Netherlands. The door opened wider, but still stayed shut to Asian and Pacific migrants.
Over the next three decades the policy eroded piece by piece rather than vanishing overnight. Migrants from southern Europe, then the Middle East, arrived through the 1950s–60s. The dictation test was scrapped in 1958. By the early 1970s, both major parties quietly accepted that a whites-only immigration rule was an embarrassment Australia could no longer defend to the world, especially as Asian trading partners and neighbours grew more important.
- 1973 — formal end of White Australia — the Whitlam Labor government removed race as a factor in immigration selection, applying the same rules to all applicants regardless of origin.
- Aftermath: Indochinese refugees — after the Vietnam War ended in 1975, Australia accepted tens of thousands of Vietnamese 'boat people' refugees through the late 1970s and 1980s, the first large wave of Asian immigration under the new non-discriminatory rules.
- Multiculturalism replaces assimilation — from the mid-1970s, government policy shifted from expecting migrants to blend in ('assimilation') to actively supporting communities keeping their languages, food, and customs while sharing a common Australian citizenship.
Debate: was 1973 a turning point or the final step of a slow decline?: Both views use good evidence. A strong essay picks a side and defends it.
**Change**: 1973 was a turning point
- 1973 is a clean, symbolic break
- A law-based whites-only policy formally ended
- It redefined who could belong
**Continuity**: the last domino
- Informal barriers remained: English-language tests, cultural bias, uneven refugee intake
- Real inclusion was gradual and partial for decades afterward
- So 1973 was really just the last domino of a process running since the 1950s

While white Australia was opening its doors to migrants, its own Indigenous peoples were still fighting for basic legal recognition. The 1967 referendum is the single most famous moment in this story, so know it precisely.
The 1967 referendum: On 27 May 1967, Australians voted on changing the constitution. Two changes passed with over 90% support, the highest 'Yes' vote in Australian referendum history.
The two changes
- Aboriginal people would now be counted in the national census
- The federal government gained the power to make laws for Aboriginal people. This was previously left to individual states, which varied hugely in how they treated Aboriginal people.
It's a common misconception that 1967 gave Aboriginal Australians the vote or citizenship — they already had both in federal law by then. What 1967 actually did was let the federal government override poor state-level treatment and count Aboriginal people properly. It mattered symbolically as a huge national vote of support, even though the practical legal change was narrower than the popular memory suggests.
Land rights followed a separate, harder legal battle. In 1966 Gurindji stockmen at Wave Hill in the Northern Territory walked off the job, demanding fair wages and the return of their traditional land — a strike that ran for eight years and became a symbol of the whole land rights movement. In 1975, Prime Minister Gough Whitlam poured a handful of soil into the hand of Gurindji leader Vincent Lingiari, symbolically returning some land. In 1992, the High Court's Mabo decision overturned the old legal idea of terra nullius, recognising that Aboriginal peoples had native title to land before Europeans arrived.
Argument: real progress on Indigenous rights
- 1967 referendum passed overwhelmingly, ending state-by-state neglect
- Mabo (1992) legally destroyed terra nullius and enabled native title claims
- Reconciliation movement built public awareness (marches, Sorry Day)
Argument: progress was slow and incomplete
- 1967 gave no new land rights — that took another 25 years to Mabo
- Native title claims are hard to prove and often contested in court
- Aboriginal Australians still face large gaps in health, education, and life expectancy today
New Zealand followed a different path because it started from a different founding document. The Treaty of Waitangi (1840) had promised Māori rights over their land, but for over a century the Crown routinely broke it. The Waitangi Tribunal, created in 1975, gave Māori a legal forum to bring claims about land and resources taken in breach of the Treaty. Its powers were extended in 1985 to investigate breaches going all the way back to 1840, unlocking decades of historic grievances for hearing.
Compare Australia and New Zealand directly: A strong essay contrasts the two paths. Naming this difference shows real comparative understanding, not just a list of dates.
Australia
- No treaty at all with Aboriginal peoples
- So its Indigenous rights story is about the constitution and the courts (1967, Mabo)
New Zealand
- A treaty from the start
- So its story is about enforcing and reinterpreting an existing promise (the Waitangi Tribunal)

Foreign policy tells the same story of change as immigration: a slow but decisive shift from Britain to the United States as the region's protector.
For over a century, Australia and New Zealand had leaned on Britain's Royal Navy for defence and Britain's markets for trade. World War II shattered that confidence — when Singapore fell to Japan in 1942, Britain proved unable to defend its own Asian empire, let alone Australia. Prime Minister John Curtin controversially declared that Australia now looked to America, 'free of any pangs', as its principal protector.
1951 — ANZUS Treaty
Australia, New Zealand, and the United States signed a mutual-defence pact, promising to consult and act together if any signatory was attacked in the Pacific. It was pushed partly because Australia and NZ wanted a security guarantee before agreeing to a lenient peace treaty with Japan, which restored Japan's independence that same year.
1954 — SEATO
The SEATO added Australia, NZ, the US, Britain, France, and Asian members (Thailand, Philippines, Pakistan) into a wider Cold War alliance aimed at containing communism's spread in Southeast Asia after France's defeat in Vietnam in 1954.
Consequence — following the US into Asian wars
Both treaties committed Australia and NZ to fight alongside the US in the region's Cold War conflicts, most significantly the Vietnam War (Australia sent combat troops from 1965; NZ from 1964), reinforcing the identity shift from British to American ally.
Fear of Japan (WWII) drove ANZUS in 1951; fear of communism (Korea) drove SEATO in 1954.
| Feature | ANZUS (1951) | SEATO (1954) |
|---|---|---|
| Members | Australia, New Zealand, USA | AUS, NZ, USA, UK, France, Thailand, Philippines, Pakistan |
| Trigger | Fear of a revived Japan + wanting a US guarantee | Cold War containment after communist gains in Indochina |
| Nature of promise | Consult and act if attacked in the Pacific | Collective defence against communist aggression/subversion |
| Later significance | Still active in 2020; strained in 1985 by NZ's anti-nuclear stance | Formally dissolved in 1977, seen as largely ineffective |
Debate: how far did Cold War conflicts serve Australia and New Zealand's own interests?: Historians disagree about why both countries joined the Korean War (1950-53) and the Vietnam War.
A genuine strategic choice
- Australia's own region (Malaya, Indonesia, Indochina) really was threatened by communist expansion
- 'Forward defence' meant fighting threats far from home before they arrived
Wars of **alliance obligation**
- Fought mainly to keep the US security guarantee sweet
- Governments exaggerated the domestic communist threat to justify sending troops the US wanted
Vietnam is the sharpest test case: By the late 1960s it produced large anti-war protests in both countries. This showed many citizens rejected the government's justification.
New Zealand's alliance path had one more twist worth knowing: in 1984-85 its government refused to allow US nuclear-armed or nuclear-powered ships to dock, a stance so firm that the US suspended its ANZUS defence obligations to New Zealand in 1986. It's a reminder that 'shift to America' was never simple or unconditional — smaller allies could and did push back.
