Western Australia Leads National Population Growth, Straining Infrastructure

Western Australia (WA) continues to experience the fastest population growth in the nation, with significant implications for infrastructure and services. Recent data from the Australian Bureau of Statistics (ABS) reveals the state is growing at a rate exceeding the national average, presenting both opportunities and challenges for the region.

Population Surge in Western Australia

According to figures released in March 2026, WA’s population reached 3.06 million in September 2025, an increase of approximately 65,800 people over the previous 12 months. This represents a growth rate of 2.2%, substantially higher than the national growth rate of 1.6% [Australian Bureau of Statistics]. Australia’s total population reached 27.7 million, with an increase of 423,600 people since September 2024.

The population increase is attributed to both natural increase (births minus deaths) and overseas migration. Nationally, natural increase accounted for 112,600 people, with a 1.9% increase in births and a 1.4% decrease in deaths. Net overseas migration contributed a further 311,000 people to the national population growth [Australian Bureau of Statistics].

Regional Growth Encouraged

Whereas WA leads in population growth, the rapid expansion is placing strain on existing infrastructure and services. Premier Roger Cook has encouraged residents to consider moving to regional towns such as Port Hedland, Karratha, Geraldton, and Kalgoorlie to alleviate pressure on Perth [Australian Bureau of Statistics].

Infrastructure Challenges

Experts highlight concerns regarding the capacity of infrastructure to keep pace with the growing population. Amanda Davies, head of the school of social services at the University of WA, notes criticism surrounding the supply of land, the development of schools and healthcare facilities, and the expansion of the public transport network. She emphasizes the need for increased focus on infrastructure development to accommodate future growth.

The Urban Development Institute’s State of the Land Report indicates a critical shortage of land in Perth, with only a 16-day supply remaining. This is the lowest level since the 2013 housing boom peak, signaling a challenging environment for prospective homebuyers.

Wage Growth and Economic Impact

Public sector wage growth is outpacing the private sector, contributing to overall wage stability. According to data from November 2025, average weekly earnings for full-time adults in ordinary time were $2,051.10 [Australian Bureau of Statistics]. The unemployment rate in February 2026 was 4.3% [Australian Bureau of Statistics]. Wage Price Index data shows a 0.8% increase in wages in the September quarter, unchanged from the previous quarter [CommBank].

Looking Ahead

With forecasts indicating continued population growth in Western Australia, sustained investment in infrastructure and strategic planning will be crucial to ensure the state can accommodate its expanding population and maintain a high quality of life. Addressing land supply issues and prioritizing the development of essential services will be key to mitigating the challenges associated with rapid growth.
