Why Are Perth and Brisbane Reshaping Australia's Business Landscape?

On 31 March 2026, the Australian Bureau of Statistics (ABS) released its *Regional Population* report, revealing the latest patterns in Australia's population movements for the 2024-25 financial year. Capital cities overall grew by 1.8%, while regional areas grew by 1.1%. Melbourne recorded the largest absolute increase of 105,030 people, while Perth was the fastest-growing capital city with a growth rate of 2.4%. More noteworthy still, the underlying structure of population movement is undergoing historic change: Sydney and Melbourne continue to lose domestic residents, while Brisbane and Perth have become the winners in internal migration. This is not merely a change in statistics—it is a commercial signal of a shift in Australia's economic geography.

Internal migration: Flows toward the resources states and Queensland

Over the financial year, capital cities collectively added 324,679 people, with overseas migration contributing 258,100, natural increase contributing 96,300, and net internal migration losing 29,800. These figures reveal an important fact: Australian residents are voting with their feet.

Brisbane recorded the largest net gain from internal migration among capital cities, at 11,077 people; Perth followed closely with 8,211. Meanwhile, Sydney recorded a net outflow of 33,282 and Melbourne a net outflow of 8,554. This directional shift is no accident. Queensland, with its relatively lower housing prices, pleasant climate, and increasingly diversified economy, has become the primary migration destination for residents of New South Wales and Victoria. Western Australia, in turn, is benefiting from the mining boom, with Perth's job opportunities and wage levels attracting large numbers of engineering and trade professionals.

Overseas migration: Sydney and Melbourne's "population lifeline"

Although Sydney and Melbourne are losing population through interstate migration, they remain the top destinations for overseas migrants. Sydney recorded a net overseas migration inflow of 78,403 people, and Melbourne 81,168—both higher than Perth (37,289) and Brisbane (33,934). This means that Sydney's and Melbourne's growth is highly dependent on overseas migration and international students.

For the commercial property and housing markets of these two cities, migrant inflows are the core driver of demand. However, it also means they are more vulnerable to changes in federal immigration policy, visa processing times, and international geopolitical developments. Should overseas migration slow, population growth in Sydney and Melbourne could cool rapidly.

Perth's resources dividend: The positive feedback loop between mining cycles and population growth

Perth's population growth rate reached 2.4%, leading all eight capital cities. This is inseparable from Western Australia's central role in Australia's resource exports. As a major export base for bulk commodities such as iron ore, lithium, gold, and natural gas, Western Australia's economic growth is closely tied to demand from the Asia-Pacific. Demand from China, Japan, South Korea, and the ASEAN market for Australia's mineral resources underpins employment and income levels in Perth, which in turn attracts population inflows.Population growth, in turn, supports the workforce needs of the resources industry and drives local infrastructure construction, residential development, and retail consumption in Perth. This positive feedback effect makes Perth one of the very few Australian cities that combine resource-driven attributes with population appeal.

Brisbane's Appeal: Lifestyle and Industrial Diversification

Brisbane's growth rate is 2.1%, second only to Perth. Unlike Perth, Brisbane has a more diversified industrial base, spanning finance, education, health, tourism, and construction. Brisbane also benefits from the long-term investment expectations associated with the 2032 Olympics. The continued net inflow of internal migration indicates that Brisbane is becoming a hub for domestic population movement in Australia.

Business-Level Insights: Who Benefits? Who Is Under Pressure?

The direction of population migration directly determines the map of business growth. Retail, dining, housing, and business service enterprises in Perth and Brisbane will gain stronger support from local customer bases. Developers and infrastructure investors should focus on the medium- and long-term supply gaps in residential and commercial real estate in these two cities.

In contrast, businesses in Sydney and Melbourne need more refined customer segmentation strategies. Since most new local arrivals are overseas migrants, their consumption patterns and living preferences differ from those of Australian-born residents. This also creates opportunities for overseas migrant services, international education, accommodation, and localized financial services.

Meanwhile, overall growth in regional areas is only 1.1%, but not all regions are sluggish. Mining towns and coastal lifestyle areas stand out. For regional areas dependent on agriculture and traditional industries, slow population growth remains a challenge for talent shortages and community sustainability.

Investment-Level Implications: Capital Flows to the Next Growth Pole

Population data is one of the most fundamental pricing factors in capital markets. The competitive landscape among Australian states is shifting. Infrastructure investors can expect the Queensland and Western Australian governments to increase capital expenditure on transport, energy, and water projects. Funds and real estate development trusts need to reassess the sustainability of population growth in different cities and their corresponding cash flow projections.

Although Melbourne has the highest absolute growth, its growth structure relies on overseas migration and experiences a net outflow of internal migration, casting doubt on the long-term stability of its housing demand. Perth and Brisbane, by contrast, are supported by both domestic and overseas migration, giving them a more balanced demand base. Over the next 5 to 10 years, the weight of these two cities in Australia's commercial landscape will increase further.

Long-Term Trends: The Overlap of Climate, Resources, and Remote Work

In addition to traditional economic drivers, climate change and remote work are reshaping population preferences. The climatic advantages of parts of northern Queensland and Western Australia, combined with more flexible working arrangements, make it possible for talent and businesses to migrate from southeastern cities to the north and west. This could lead to further spatial dispersion of business activity across Australia.For policymakers, population data is not just numbers in statistical yearbooks, but an important reference for future demand, taxation, and fiscal allocation. State governments should view population growth rationally and plan ahead for housing, water, transportation, education, and healthcare resources to meet the challenges of demographic change.

Conclusion

The regional population data for the 2024-25 fiscal year clearly demonstrates the profound changes in Australia's economic geography. Perth and Brisbane, with their resource boom, cost-of-living advantages, and industrial diversification, have become magnets for domestic migration; Sydney and Melbourne, while still vast, increasingly depend on overseas migration for growth. For businesses, investors, and policymakers, understanding and adapting to the direction of this population movement is key to seizing the next phase of Australian business opportunities.

Key Takeaways

• Capital city population growth of 1.8% far exceeds the 1.1% in regional areas, with regional imbalances continuing to intensify.
• Perth leads with 2.4% growth, followed closely by Brisbane (2.1%); resource-based cities and state capitals are becoming engines of population growth.
• Sydney (net outflow of 33,282 people) and Melbourne (net outflow of 8,554 people) are losing population in internal migration, but overseas migration fills the gap.
• Overseas migration (258,100 people) is the largest source of net growth for capital cities, not domestic migration.
• Population movement to Queensland and Western Australia will reshape the investment landscape of Australia's commercial real estate, infrastructure, and labor markets.
