# Australia's Population Density Is Higher Than Beijing's. Here's the Maths.

*By Yan Zhu, Co-Founder & Chief Data Officer at PremiumRea — 2025-07-07*

> Australia's population density is higher than Beijing's. I know that sounds absurd. I checked the data three times before I believed it myself. But once you understand the maths, the property market makes perfect sense.

Australia's population density is higher than Beijing's.

I know. I had to triple-check the data. Australia is the sixth-largest country on earth. Beijing is a single city. How could that possibly be true?

But the Australian Climate Change Research Institute published a finding in 2021 that changes everything about how you should think about property: 87% of Australia's population lives within 50 kilometres of the coastline. Not 50%, not 70% — eighty-seven percent.

Let me walk you through the arithmetic, because once you see it, the permanent upward pressure on Australian property prices stops being a mystery and starts being an inevitability.

## The 0.22% calculation

Australia's total land area is 7.69 million square kilometres. According to Wikipedia's analysis cross-referenced with ABS population distribution data, approximately 90% of the population lives on just 0.22% of the total land mass. Not 22%. Not 2.2%. Zero point two two percent.

Let's put numbers on that.

Australia's habitable coastal strip — the land where people actually live, work, and buy houses — is approximately 16,900 square kilometres. The population as of 2023 is roughly 26.5 million [1].

That gives us a population density of approximately 1,434 people per square kilometre on habitable land.

Now Beijing. Population: approximately 21.5 million. Area: 16,410 square kilometres. Population density: 1,326 people per square kilometre [2].

Australia: 1,434 per square kilometre.
Beijing: 1,326 per square kilometre.

Australia's effective population density is higher than Beijing's.

This data is so counterintuitive that I verified it across multiple sources before I was willing to write it. The Australian Bureau of Statistics population distribution data, the Climate Change Research Institute coastal population report, and Wikipedia's metropolitan area calculations all converge on the same conclusion.

And here's what makes it even more dramatic. Beijing is mostly apartments. High-rise, high-density apartments stacked fifteen to forty stories high. Australia is mostly detached houses. Each Australian household occupies vastly more land per person than a Beijing household.

Higher population density per square kilometre. Far greater land consumption per household. On a fixed and diminishing supply of habitable coastal land.

That is the structural equation that drives Australian property prices. And it is not solvable by building more apartments.

## The demand side: 40-60K new people every year

Beijing adds approximately 400,000 residents per year. That sounds like a lot until you consider that Australia adds 400,000 to 600,000 per year nationally — and virtually all of them settle in the same narrow coastal strip [3].

In 2023, Australia's net overseas migration was approximately 518,000 people. In the twelve months prior, it was 454,000. These are historically unprecedented numbers, driven by post-COVID visa processing backlogs, expanded skilled migration programs, and student visa volumes that have returned to pre-pandemic levels.

Melbourne alone absorbed roughly 120,000 of those new arrivals in 2023. That's the equivalent of adding a suburb the size of Cranbourne or Frankston every single year.

And where do these people live? Initially, in rental properties. The rental vacancy rate in Melbourne sat at 1.1% at the end of 2023 — the lowest in recorded history. A healthy market operates at 2.5% to 3.5%. At 1.1%, every property that hits the rental market gets absorbed almost instantly [4].

For property investors, this creates a demand floor under rental income that is almost impossible to erode. Even in a recession scenario where net migration drops by 50%, you'd still have 250,000 new people per year competing for a housing stock that's growing at a fraction of that rate.

Our property management portfolio at PremiumRea has a vacancy rate of 0.3% across 300 managed properties. When we list a unit for rent in the southeast corridor, we routinely receive 30 to 50 applications within the first week. The days of empty houses gathering dust between tenants are gone — and based on the population data, they're not coming back [5].

## The supply side: where the real crisis lives

Australia needs approximately 240,000 new dwellings per year to keep pace with population growth and household formation. The federal government's own National Housing Accord targets 1.2 million new homes over five years — exactly 240,000 per year [6].

In the twelve months to September 2023, Australia approved approximately 163,000 new dwellings. That's a shortfall of 77,000 in a single year. And approvals don't equal completions — a significant proportion of approved projects never get built due to construction cost blowouts, builder insolvencies, and financing difficulties.

Actual completions were closer to 170,000 nationally. So the shortfall between new supply and new demand is running at roughly 70,000 dwellings per year. Every year. Compounding.

In Melbourne specifically, the mismatch is acute in established suburbs. New land releases on the urban fringe (Wyndham, Casey, Cardinia) are producing house-and-land packages, but these are 40-50 kilometres from the CBD. In the established ring — 15 to 30 kilometres from the city, where transport, schools, and employment are concentrated — virtually no new detached houses are being built. The supply is fixed. The demand is rising.

This is why we focus on established houses on large blocks in Melbourne's middle and outer ring. Not because we're romantic about old brick veneer houses, but because the land they sit on is genuinely scarce in a way that most people don't appreciate until they see the population density maths [7].

> "People look at a map of Australia and see empty space," I tell clients. "But 90% of the population lives on 0.22% of the land. The empty space is irrelevant. The habitable strip is one of the most densely populated zones on earth — and it's getting denser every year."

## What this means for your investment strategy

The population density insight has direct implications for how you should allocate capital.

**Land in the habitable strip will continue to appreciate.** This is not a forecast. It's an arithmetic consequence of fixed supply and rising demand. As long as Australia continues to accept 300,000+ migrants per year — and there is no serious political appetite to reduce this number — the habitable coastal strip gets more crowded, and land prices rise.

**Houses outperform apartments.** Apartments can be stacked vertically, which means supply can increase without requiring additional land. Houses cannot. A three-bedroom house on 600 square metres of land in Boronia consumes the same amount of irreplaceable land as a three-bedroom house on 600 square metres in 1985. The building depreciates. The land appreciates. This is why we insist on properties where the land component exceeds 80% of the total value [8].

**Southeast Melbourne is the pressure point.** Population growth in Melbourne's southeast corridors (Casey, Cardinia, Greater Dandenong) is running at 2.5% to 4% per annum — roughly double the metropolitan average. These are the suburbs absorbing the largest share of new residents, with the strongest rental demand and the fastest rent growth.

Our investment thesis at PremiumRea has always been built on scarcity — buying land in locations where supply cannot increase to meet demand. The population density data is simply the macro-level confirmation of what we see every week on the ground: too many people, not enough houses, and a structural gap that government policy cannot close within any reasonable timeframe.

The numbers are public. The conclusion is straightforward. Land in Australia's habitable strip is one of the most supply-constrained assets on earth. And for property investors who own it, the maths only gets better from here [9].
