Miller

Miller has seen population growth performance typically on par with national averages when looking at short and medium term trends

Based on analysis of ABS population updates for the broader area and new addresses validated by AreaSearch, the estimated population of Miller as of Feb 2026 is around 3,462. This reflects an increase of 88 people (2.6%) since the 2021 Census, which reported a population of 3,374 people. The change is inferred from the resident population of 3,411 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 17 validated new addresses since the Census date. This level of population equates to a density ratio of 2,726 persons per square kilometer, placing Miller in the upper quartile relative to national locations assessed by AreaSearch. Population growth for the suburb was primarily driven by overseas migration that contributed approximately 52.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Examining future population trends, an above median growth is projected for the suburb, expected to expand by 709 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 19.4% in total over the 17 years.

AreaSearch assessment of residential development drivers sees a low level of activity in Miller, placing the area among the bottom 25% of areas assessed nationally

AreaSearch analysis of ABS building approval numbers shows Miller recorded around 13 residential properties granted approval per year over the past five financial years from FY-21 to FY-25. This totals an estimated 68 homes. As of FY-26, 7 approvals have been recorded.

On average, 0.1 people moved to the area for each dwelling built during this period. New supply has kept pace with or exceeded demand, providing ample buyer choice and capacity for population growth beyond current forecasts. The average construction cost value of new homes was $222,000, below the regional average. Compared to Greater Sydney, Miller had significantly less development activity, 80.0% below the regional average per person as of FY-26.

This limited supply generally supports stronger demand and values for established homes. New building activity consisted of 73.0% standalone homes and 27.0% medium and high-density housing, preserving Miller's suburban nature with an emphasis on detached housing attracting space-seeking buyers. The area reflected a low density with around 284 people per approval. Miller is expected to grow by 673 residents through to 2041, according to the latest AreaSearch quarterly estimate. Construction has maintained a reasonable pace with projected growth, although buyers may encounter growing competition as population increases.

As of September 2025860 residents are employed while the unemployment rate stands at 14.1%, significantly higher than Greater Sydney's 4.2%.

Conversely, professional & technical services employ only 1.6% of local workers, below Greater Sydney's 11.5%. Employment opportunities locally may be limited, as indicated by Census data on working population vs resident population. Between September 2024 and September 2025, employment levels increased by 6.8%, while labour force grew by 2.4%, reducing the unemployment rate by 3.4 percentage points. In contrast, Greater Sydney recorded employment growth of 2.1% with a slight rise in unemployment. Jobs and Skills Australia's national employment forecasts from May-25 project overall expansion of 6.6% over five years and 13.7% over ten years. Applying these projections to Miller's employment mix suggests local employment should increase by 5.9% over five years and 12.8% over ten years, though these are simple extrapolations for illustrative purposes only.
