For future projections until 2041, AreaSearch is adopting ABS/Geoscience Australia's SA2-level projections released in 2024 with a base year of 2022, and NSW State Government's SA2 level projections for areas not covered by this data, with a base year of 2021.

Based on these aggregations, Harrington Park is expected to grow by approximately 7.3% to reach around 14,536 persons by 2041.

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

Harrington Park has seen 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 an additional 8 approved in FY-26. On average, 4.4 people moved to the area per dwelling built over these five years.

This indicates substantial demand outstripping supply, leading to heightened buyer competition and pricing pressures. Developers are targeting the premium market segment, with new homes valued at approximately $478,000 on average. In FY-26, there have been $73,000 in commercial development approvals, suggesting minimal commercial development activity. Compared to Greater Sydney, Harrington Park has significantly reduced construction levels, 72.0% below the regional average per person. This limited new supply supports stronger demand and values for established properties.

The area's construction composition is 86.0% standalone homes and 14.0% townhouses or apartments, preserving its suburban nature and attracting space-seeking buyers. Harrington Park has around 1429 people per approval, reflecting a mature, established area. Population forecasts indicate the area will gain approximately 993 residents by 2041, with construction maintaining a reasonable pace to meet projected growth. However, increasing population could lead to growing competition among buyers.
