Natural growth contributed approximately 50.7% to overall population gains during recent periods.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022, and NSW State Government's SA2 level projections for areas not covered by this data, 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 dynamics suggest an increase just below the median of statistical areas analysed by AreaSearch, with Harrington Park expected to grow by 740 persons to 2041 based on latest numbers, reflecting a total increase of 6.5% over these 17 years.

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

Harrington Park averaged approximately 13 new dwelling approvals per year. Over the past five financial years, from FY21 to FY25, a total of 66 homes were approved, with an additional 3 approved so far in FY26. Each dwelling built over this period attracted an average of 2.6 new residents annually.

The average construction cost value for these dwellings was $404,000. In the current financial year, there have been $50,000 in commercial development approvals, reflecting the area's residential nature. Compared to Greater Sydney, Harrington Park has significantly lower building activity, at 74.0% below the regional average per person. This scarcity typically strengthens demand and prices for existing properties. Nationally, the area also records a below-average level of new home construction, indicating maturity and potential planning constraints.

All new constructions in Harrington Park have been detached dwellings, preserving its suburban character and attracting space-seeking buyers. With around 2468 people per dwelling approval, it reflects a highly mature market. Population forecasts suggest Harrington Park will gain 746 residents by 2041. Building activity is currently aligned with these growth projections, but increased competition among buyers can be expected as the population grows.
