Harrington Park

Population growth drivers in Harrington Park are strong compared to national averages based on AreaSearch's ranking of recent, and medium to long-term trends

As of May 2026, the estimated population of Harrington Park is around 13,724. This figure reflects an increase of 392 people since the 2021 Census, which reported a population of 13,332. The current estimate is based on AreaSearch's validation of new addresses and examination of the latest ERP data release by the ABS in June 2025. This results in a resident population estimate of 13,719 with an additional 28 validated new addresses since the Census date. The population density ratio is 1,715 persons per square kilometer, above the average seen across national locations assessed by AreaSearch. Over the past decade, Harrington Park has shown resilient growth patterns with a compound annual growth rate of 3.1%, outpacing the SA3 area.

Natural growth contributed approximately 54.0% of overall population gains during recent periods. For future projections, 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, NSW State Government's SA2 level projections are used, 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. By 2041, the suburb is expected to grow by 788 persons, reflecting an increase of 5.7% in total over the 16-year period, with a projected population just below the median of Australian statistical areas.

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

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Harrington Park has seen around 17 new homes approved each year. Over the past five financial years, between FY21 and FY25, approximately 86 homes were approved, with an additional 10 approved so far in FY26. On average, about 11.4 people have moved to the area for each dwelling built over these five years.

This supply lagging demand suggests heightened buyer competition and pricing pressures. New homes are being built at an average expected construction cost value of $478,000, indicating developers target the premium market segment with higher-end properties. In FY26, commercial development approvals totalled $73,000, reflecting minimal commercial development activity. Compared to Greater Sydney, Harrington Park shows substantially reduced construction, 71.0% below the regional average per person. This limited new supply generally supports stronger demand and values for established properties.

Nationally, this is also below average, which reflects the area's maturity and possible planning constraints. Recent construction comprises 86.0% standalone homes and 14.0% townhouses or apartments, preserving Harrington Park's suburban nature with an emphasis on detached housing attracting space-seeking buyers. With around 1430 people per approval, Harrington Park shows a mature, established area. Population forecasts indicate Harrington Park will gain approximately 783 residents through to 2041, based on the latest AreaSearch quarterly estimate. Construction is maintaining a reasonable pace with projected growth, although buyers may encounter growing competition as population increases.

Harrington Park's skilled workforce is notable, particularly in the construction sector. Its unemployment rate was 1.4% as of December 2025, with an estimated employment growth of 7.2% over the past year. This figure is based on AreaSearch aggregation of statistical area data.

As of December 2025, 8951 residents were employed, with an unemployment rate of 2.7%, below Greater Sydney's rate of 4.2%. Workforce participation was high at 84.1% compared to Greater Sydney's 68.8%. According to Census responses, 38.5% of residents worked from home, potentially influenced by Covid-19 lockdowns. Leading employment industries were construction, health care & social assistance, and education & training.

Construction had a strong representation at 1.6 times the regional level. Conversely, professional & technical services showed lower representation at 6.3% versus the regional average of 11.5%. Employment opportunities locally appeared limited based on Census working population vs resident population comparison. Over the year to December 2025, employment increased by 7.2%, while labour force grew by 7.4%, leading to a slight rise in unemployment rate by 0.2 percentage points. Greater Sydney recorded lower employment and labour force growth rates with marginal unemployment increase. Jobs and Skills Australia's national employment forecasts from May-25 project overall employment growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Harrington Park's employment mix suggests local employment should increase by 6.3% over five years and 12.9% over ten years, though this is a simple extrapolation for illustrative purposes only.
