Harrington Park's population is estimated at around 13,635 as of Feb 2026. This reflects an increase of 303 people since the 2021 Census, which reported a population of 13,332 people. The change is inferred from AreaSearch's estimation of the resident population at 13,627 following examination of ABS's ERP data release in June 2024 and an additional 29 validated new addresses since the Census date.

Population growth was primarily driven by natural growth contributing approximately 54.0% 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. Future population trends suggest an increase just below the median of Australian statistical areas, with Harrington Park expected to grow by 1,037 persons to 2041 based on aggregated SA2-level projections, reflecting a total increase of 7.5% over the 17 years.

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

Harrington Park saw approximately 17 new homes approved annually based on AreaSearch analysis of ABS building approval numbers. Around 86 homes were approved between financial years FY-21 to FY-25, with 7 more approved in FY-26 so far. On average, about 4.2 people moved to the area for each dwelling built over those five years.

This indicates substantial lagging supply compared to demand, likely leading to heightened buyer competition and pricing pressures. New homes are being constructed at an average value of $478,000, suggesting developers target the premium market segment with higher-end properties. In FY-26, there have been $73,000 in commercial development approvals, indicating minimal commercial development activity. Compared to Greater Sydney, Harrington Park has significantly reduced construction rates, at 71.0% below the regional average per person. This limited new supply generally supports stronger demand and values for established properties.

The area's recent construction comprises 86.0% standalone homes and 14.0% townhouses or apartments, preserving its suburban nature with an emphasis on detached housing attracting space-seeking buyers. Harrington Park has around 1428 people per approval, indicating a mature, established area. Population forecasts suggest the area will gain 1,029 residents by 2041 (latest AreaSearch quarterly estimate). Construction is maintaining a reasonable pace with projected growth, although buyers may encounter growing competition as population increases.
