How Melbourne Became One of the World's Most Diverse Cities, and Why That Story Is Getting Complicated

More than 40 per cent of Melbourne's 5.3 million residents were born overseas. That single statistic, drawn from the Australian Bureau of Statistics' 2021 census data and updated by state government projections through 2025, explains more about this city than almost any other number. It explains the dim sum restaurants running three sittings on a Sunday morning in Box Hill. It explains the Vietnamese legal aid clinics operating out of community halls in Footscray. It explains why the Victorian Curriculum and Assessment Authority now lists 55 languages taught in state schools. Melbourne did not arrive at this point by accident.

The timing matters. Federal immigration settings have shifted sharply in the past 18 months, with the Albanese government's post-pandemic migration review, finalised in late 2024, cutting the permanent migration program cap from 195,000 to 185,000 places annually. Temporary visa processing backlogs, which peaked at over 1 million outstanding applications nationally in mid-2024, have only partially cleared. For Melbourne's established migrant communities, many of whom sponsor family members and anchor settlement networks, that administrative gridlock has real human consequences sitting in waiting rooms and community legal centres right now.

A History Built in Waves

Melbourne's multicultural character did not emerge from a single policy decision but from a series of them, each responding to a different crisis or political moment. The first wave came after World War II. The Chifley government's mass migration scheme, launched in 1947 under immigration minister Arthur Calwell, brought tens of thousands of displaced Europeans, Greeks, Italians, Poles, Latvians, to a city that had barely 1.3 million people. The docks at Station Pier in Port Melbourne were the entry point for most of them. Entire neighbourhoods reshaped within a decade: Brunswick filled with Lebanese and Turkish families through the 1970s; Richmond's Victoria Street became a Vietnamese commercial strip after the fall of Saigon in 1975 brought refugee resettlement programs into effect.

The formal dismantling of the White Australia Policy, completed through the Whitlam government's Racial Discrimination Act of 1975, opened the door to a broader transformation. Through the 1980s and 1990s, skilled migration from China, India, the Philippines and Southeast Asia accelerated under both Labor and Coalition governments. The Howard-era points-tested skilled migration system, introduced in the late 1990s, prioritised education credentials and English proficiency, reshaping who arrived and where they settled. Dandenong, in Melbourne's southeast, absorbed a substantial Cambodian, Afghan and Sudanese population through the refugee and humanitarian streams that ran alongside the skilled programs. The Australian Multicultural Foundation, headquartered in Carlton, has documented these settlement shifts in longitudinal research spanning more than two decades.

What the Numbers Show Now

The City of Greater Dandenong remains the most ethnically diverse local government area in Australia by some measures, with residents speaking more than 150 languages. The City of Melbourne itself recorded 43 per cent of residents born overseas in the 2021 census, with India overtaking China as the largest source country for the first time. Across Victoria, the Department of Home Affairs data shows the state received approximately 87,000 new permanent migrants in the 2024-25 financial year, down from a post-pandemic peak of 112,000 in 2022-23.

Those numbers have direct implications for housing, which sits at the centre of the Allan government's current density reform debate. Settlement services providers, including the Refugee Legal centre on Lonsdale Street and the Multicultural Communities Council of Victoria based in Footscray, have flagged that newly arrived families on temporary visas are increasingly priced out of inner and middle-ring suburbs where established community networks, the cultural grocery stores, the language schools, the faith communities, actually exist.

For Melburnians watching these pressures build, the practical picture is this: the settlement infrastructure, legal services, English-language programs under the Adult Migrant English Program, community health centres, was designed for a slower, more predictable intake. The organisations running those services are now operating with funding formulas set in 2021, against a cost base that has risen sharply since. State budget submissions from several peak multicultural bodies are sitting with the Victorian Department of Premier and Cabinet ahead of the mid-year review expected in August. What comes out of that process will determine, in very practical terms, how well the next wave of arrivals lands.
