Thornbury

Population growth drivers in Thornbury are slightly above average based on AreaSearch's ranking of recent, and medium term trends

Based on AreaSearch's analysis, Thornbury's population is around 20,490 as of Feb 2026. This reflects an increase of 1,571 people (8.3%) since the 2021 Census, which reported a population of 18,919 people. The change is inferred from the estimated resident population of 19,982 from the ABS as of June 2024 and an additional 103 validated new addresses since the Census date. This population level equates to a density ratio of 4,098 persons per square kilometer, which lies in the top 10% of national locations assessed by AreaSearch, making land in the area a highly sought resource. Thornbury's 8.3% growth since the census positions it within 0.4 percentage points of the SA3 area (8.7%), demonstrating competitive growth fundamentals. Population growth for the area was primarily driven by overseas migration, which contributed approximately 81.3% 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. Considering the projected demographic shifts, a significant population increase in the top quartile of statistical areas across the nation is forecast, with the area expected to increase by 7,721 persons to 2041 based on the latest annual ERP population numbers, reflecting an increase of 35.2% in total over the 17 years.

Residential development activity is lower than average in Thornbury according to AreaSearch's national comparison of local real estate markets

Thornbury has averaged around 58 new dwelling approvals per year, with 290 homes approved over the past 5 financial years (between FY-21 and FY-25) and 51 so far in FY-26. With an average of only 0.9 people per year moving to the area for each dwelling built over the past 5 financial years (between FY-21 and FY-25), new supply is keeping pace with or exceeding demand, offering ample buyer choice and creating capacity for population growth beyond current forecasts, while new homes are being built at an average value of $403,000. Additionally, $48.7 million in commercial development approvals have been recorded this financial year, indicating strong commercial development momentum.

When measured against Greater Melbourne, Thornbury has 13.0% less new development (per person) while it places among the 36th percentile of areas assessed nationally, meaning somewhat limited buyer options while strengthening demand for established properties. This activity is likewise lower than nationally, reflecting market maturity and pointing to possible development constraints. Recent construction comprises 39.0% standalone homes and 61.0% townhouses or apartments. This focus on higher-density living creates more affordable entry points and suits downsizers, investors, and first-home buyers. With around 551 people per dwelling approval, Thornbury shows a developed market.

Looking ahead, Thornbury is expected to grow by 7,213 residents through to 2041 (from the latest AreaSearch quarterly estimate). If current development rates continue, housing supply may not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth.

Thornbury has seen below average employment performance when compared to national benchmarks

Thornbury features a highly educated workforce, with the technology sector a particular standout in terms of representation, an unemployment rate of 7.3%, and 3.8% in estimated employment growth over the past year. As of December 2025, 12,319 residents are in work while the unemployment rate is 2.5% above Greater Melbourne's rate of 4.8%, and workforce participation is well beyond standard (77.3% compared to Greater Melbourne's 71.3%). Based on Census responses, a high 48.1% of residents were found to work from home, though Covid-19 lockdown impacts should be considered.

Leading employment industries among residents comprise health care & social assistance, professional & technical, and education & training. The area demonstrates a particularly notable concentration in professional & technical, with employment levels at 1.4 times the regional average. In contrast, construction employs just 6.1% of local workers, below Greater Melbourne's 9.7%. The predominantly residential area appears to offer limited employment opportunities locally, as indicated by the count of Census working population vs resident population.

Based on AreaSearch analysis of SALM and ABS data, during the year to December 2025, employment levels increased by 3.8% and labour force increased by 4.5%, causing the unemployment rate to rise by 0.7 percentage points. By comparison, Greater Melbourne recorded employment growth of 2.4%, labour force growth of 2.8%, with unemployment rising 0.3 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 can offer further insight into potential future demand within Thornbury. 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 Thornbury's employment mix suggests local employment should increase by 7.1% over five years and 14.4% over ten years (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections).

Higher earners represent a substantial presence with 31.0% exceeding $3,000 weekly, indicating strong purchasing power within the community. High housing costs consume 16.1% of income, though strong earnings still place disposable income at the 64th percentile and the area's SEIFA income ranking places it in the 8th decile.
