Cairnlea

Population growth drivers in Cairnlea are above average based on AreaSearch's ranking of recent, and medium to long-term trends

Based on AreaSearch's analysis, Cairnlea's population is around 10,045 as of Feb 2026. This reflects an increase of 7 people (0.1%) since the 2021 Census, which reported a population of 10,038 people. The change is inferred from the estimated resident population of 10,045 from the ABS as of June 2024 and address validation since the Census date. This population level equates to a density ratio of 2,277 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Over the past decade, Cairnlea has demonstrated resilient growth patterns with a 0.2% compound annual growth rate, outpacing the SA3 area. Population growth for the area was primarily driven by overseas migration, which contributed approximately 66.1% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, AreaSearch is utilising the VIC State Government's Regional/LGA projections released in 2023 with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Growth rates by age group from these aggregations are also applied across all areas for years 2032 to 2041. Looking at population projections moving forward, an above-median population growth of statistical areas across the nation is projected, with the area expected to increase by 1,793 persons by 2041 based on the latest annual ERP population numbers, reflecting a gain of 17.9% in total over the 17 years.

The level of residential development activity in Cairnlea is very low in comparison to the average area assessed nationally by AreaSearch

Cairnlea has averaged around 11 new dwelling approvals each year, with 57 homes approved over the past 5 financial years (between FY-21 and FY-25) and 8 so far in FY-26. Given population has fallen over the past period, housing supply has remained adequate relative to demand, creating a well-balanced market with good buyer choice, while new dwellings are developed at an average value of $452,000—slightly above the regional average—suggesting a focus on quality developments. There have also been $19.6 million in commercial approvals this financial year, demonstrating moderate levels of commercial development.

Relative to Greater Melbourne, Cairnlea has significantly less development activity (63.0% below regional average per person). This scarcity of new properties typically strengthens demand and prices for existing properties. This is also below average nationally, reflecting the area's maturity and pointing to possible planning constraints. Meanwhile, recent building activity consists entirely of detached houses, preserving the area's suburban nature with an emphasis on detached housing attracting space-seeking buyers. With around 1559 people per dwelling approval, Cairnlea reflects a highly mature market.

Future projections show Cairnlea adding 1,793 residents by 2041 (from the latest AreaSearch quarterly estimate). Should current construction levels persist, housing supply could lag population growth, likely intensifying buyer competition and underpinning price growth.

Cairnlea has moderate levels of nearby infrastructure activity, ranking in the top 50% nationally

The employment landscape in Cairnlea shows performance that lags behind national averages across key labour market indicators

Cairnlea possesses a skilled workforce with diverse sector representation, an unemployment rate of 4.8%, and 3.7% estimated employment growth over the past year. As of December 2025, 5,563 residents are in work, while the unemployment rate is in line with Greater Melbourne's rate of 4.8%, and workforce participation is broadly similar to Greater Melbourne's 71.3%. Based on Census responses, a moderate 21.3% of residents were found to work from home, though Covid-19 lockdown impacts should be considered.

Employment among residents is concentrated in retail trade, health care & social assistance, and manufacturing. The area demonstrates a particularly notable concentration in transport, postal & warehousing, with employment levels at 2.0 times the regional average. Meanwhile, professional & technical services have a limited presence with 5.9% employment compared to 10.1% regionally. The predominantly residential area appears to offer limited employment opportunities locally, as indicated by the count of the Census working population versus the resident population.

Based on AreaSearch analysis of SALM and ABS data, the 12-month period saw employment increase by 3.7% alongside a labour force increase of 4.3%, causing the unemployment rate to rise by 0.5 percentage points. This contrasts with Greater Melbourne, where employment rose by 2.4%, the labour force grew by 2.8%, and unemployment rose 0.3 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 can offer further insight into potential future demand within Cairnlea. These projections, covering five and ten-year periods, have been mapped against the local employment profile to estimate growth patterns. While national employment is forecast to expand by 6.6% over five years and 13.7% over ten years, growth rates differ significantly between industry sectors. Applying these industry-specific projections to Cairnlea's employment mix suggests local employment should increase by 5.9% over five years and 12.5% over ten years (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections).
