Population Center Shifts West: How the Rise of Perth and Brisbane is Reshaping Australia's Business Landscape

Introduction

Data on regional population for the 2024-25 financial year released by the Australian Bureau of Statistics (ABS) on March 31 show that the combined population of the nation's capital cities grew by 324,700, an increase of 1.8%. Among them, Melbourne led in absolute growth with an increase of 105,000, Perth led the nation with a growth rate of 2.4%, and Brisbane followed closely. At the same time, both Sydney and Melbourne recorded negative net internal migration, while Perth and Brisbane were the only capital cities with net internal migration gains. This westward and northward shift in the population map is having a profound impact on Australia's resources industry, infrastructure investment, and the Asia-Pacific trade landscape.

Background

As of June 30, 2025, the total population of Australia's capital cities had reached 18.751 million, accounting for roughly 70 percent of the national population. In terms of growth composition, overseas migration contributed 258,100 people, natural increase contributed 96,300 people, and net internal migration decreased by 29,800 people. This means that growth in the capital cities is almost entirely supported by overseas migration, while domestic residents are voting with their feet, moving from the high-cost southeastern coastal cities to resources and energy hubs with more economic opportunities and relatively more affordable housing.

Looking at specific cities, Sydney's population rose to 5.639 million, an increase of 75,200, but it recorded a net internal outflow of 33,300, making it the city with the largest loss in the country. Melbourne's population rose to 5.436 million, an increase of 105,000, but it saw a net internal outflow of 8,554. Brisbane's population rose to 2.834 million, an increase of 58,200, with a net internal inflow of 11,100. Perth's population rose to 2.453 million, an increase of 58,100, with a net internal inflow of 8,211. Together, these figures paint a clear picture of population movement: Australia's economic center of gravity is shifting from the "traditional twin cities" in the south to the "resources corridor" in the northwest.

In-Depth Analysis

Business Level: The Multiplier Effect of the Resources States

The rapid growth of Perth and Brisbane is no coincidence. Western Australia is Australia's global export hub for iron ore, LNG, and lithium, while Queensland is a major province for coal, natural gas, and renewable energy. During the 2024-25 financial year, although global commodity prices fluctuated somewhat, demand from Asian markets remained strong, directly driving mining investment and employment in Western Australia and Queensland. As the capital of Western Australia, Perth has enjoyed a virtuous cycle of rising wages, business expansion, and population inflow amid the mining boom. Brisbane, in turn, has benefited from Queensland's natural gas exports, preparations for the 2032 Olympics, and a wave of renewable energy projects.For businesses in these cities, population growth means a double dividend: on the one hand, local demand for housing, retail, healthcare, and education expands, creating new market space; on the other hand, a more abundant labor supply eases labor shortages in mining and construction. Among companies listed on the ASX, resource stocks, banks, and property companies with businesses highly concentrated in Western Australia and Queensland may continue to benefit from this population centripetal force over the next several years. By contrast, although the absolute populations of Sydney and Melbourne are still rising, the trend of net domestic outflows will force companies to more actively pursue cost control and productivity improvements to cope with tighter local labor markets and upward wage pressure.

Industry level: From the "manufacturing belt" to a "resources + services" corridor

Melbourne remains the city with the largest absolute growth, indicating that its appeal in education, finance, and high-end services has not weakened. However, the continued outflow of domestic residents reflects a deep structural change: the attractiveness of Australia's manufacturing and traditional services clusters is being diluted by the "late-mover advantage" of resource-based economic zones.

In recent years, the federal government and state governments have introduced a large number of investment incentives in critical minerals, hydrogen, and clean energy. Western Australia has globally significant lithium processing capacity, while Queensland has established multiple hydrogen and green ammonia projects. Population migration to these regions will accelerate the formation of industrial clusters, such as lithium salt refining around Perth and renewable energy equipment manufacturing west of Brisbane. For engineering contractors, equipment suppliers, and logistics companies, this will be a once-in-a-decade growth window.

At the same time, population growth also tests the carrying capacity of local infrastructure. Perth's urban traffic congestion is becoming increasingly prominent, Brisbane's metro project is still under construction, and the reliability of electricity supply is being contested by resource projects. This brings orders to large infrastructure companies, but also requires state governments to accelerate the pace of approvals and investment.

Trade level: Further integration with Asian supply chains

Perth and Brisbane are the physical nodes connecting Australia with Asia-Pacific markets. Western Australia's iron ore and LNG are mainly shipped to China, Japan, and South Korea, while Queensland's coal and natural gas are exported in large volumes to India, Southeast Asia, and Northeast Asia. Population growth first alleviates labor shortages in port and railway operations in these regions, and secondly expands the base for accommodating Asian immigrants and international students.

In terms of migration composition, overseas immigration remains the core driver of capital city growth. Melbourne and Sydney attract the most overseas immigrants, but a growing number of skilled migrants choose to move to Perth or Brisbane after obtaining permanent residency, because there are more job opportunities and lower living thresholds there. This path of "landing first, then relocating" objectively strengthens the cultural ties between resource states and Asian markets, helping Australia deepen its trade partnerships with ASEAN and India.

Investment level: Capital follows populationPopulation data has always been a key anchor for capital allocation. Perth's 2.4% growth rate means its housing shortfall and commercial real estate demand will continue to expand. Pension funds, commercial real estate trusts, and infrastructure funds have already increased—or will increase—their investment in these two cities. From a listed-company perspective, same-store sales growth for mortgage banks, building material suppliers, and retail chains in Western Australia and Queensland is likely to be higher than the national average.

On the other hand, population outflows from Sydney and Melbourne, while unlikely to change their status as commercial centers in the short term, will slow the growth of their housing demand and put some pressure on the rental prospects for office and retail properties. Investors need to reassess their exposure to each state, especially Australian superannuation funds, which are increasingly inclined to allocate to real assets related to resource exports and population migration.

Long-term trends: the energy transition will further reshape the population map

Looking at the next 3–10 years, population distribution will become more closely tied to the global decarbonization process. Western Australia and Queensland are currently known for traditional fossil fuel exports, but they also have extremely abundant solar and wind resources. As the cost of energy storage and hydrogen technology declines, these regions are expected to become "green energy super-export hubs," attracting a new round of labor and capital inflows. At the same time, climate change could also drive reverse migration: cooler southern coastal areas (such as Tasmania and southern Victoria) may attract populations seeking to escape extreme heat, although this effect is not yet clearly visible in the data.

For Australian businesses and policymakers, the 2024–25 fiscal year population data is an important reference for determining future business strategy. It shows that the national growth pattern is no longer dominated by the "Sydney–Melbourne" duo, but is a multipolar network driven jointly by resource corridors, Olympic cities, and immigration gateways. Companies that can position themselves early in Perth and Brisbane and seize the first-mover advantage in infrastructure, housing, and energy services are likely to benefit in the next growth cycle.

Conclusion

The most important insight from the regional population data for the 2024–25 fiscal year is not how much a particular city's population increased, but that the map of Australia's economic growth is undergoing a structural shift. Overseas immigration supported overall capital-city population growth, but the direction of domestic migration clearly points to Perth and Brisbane—to the lands most closely connected to the Asia-Pacific export supply chain and the energy transition.

For business decision-makers, this means reassessing market potential and labor supply across states; for investors, it means tracking real estate, infrastructure, and energy opportunities in the resource states; for policymakers, it means accelerating key infrastructure construction to ensure that population growth is not stalled by bottlenecks in water, electricity, and transport.

Those who understand population can understand the future of Australian business. Whoever can adjust strategy in time by following population flows will occupy a more favorable position in this resilient economy.
