West Pennant Hills

West Pennant Hills is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

Based on analysis of ABS population updates for the broader area, as of November 2025, West Pennant Hills' estimated population is around 16,674. This reflects an increase of 54 people since the 2021 Census, which reported a population of 16,620. The change is inferred from AreaSearch's estimate of the resident population at 16,536 following examination of the latest ERP data release by the ABS in June 2024, and an additional 45 validated new addresses since the Census date. This level of population results in a density ratio of 1,794 persons per square kilometer, above the average seen across national locations assessed by AreaSearch. Population growth was primarily driven by overseas migration contributing approximately 83.0% 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, 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. Considering projected demographic shifts, the West Pennant Hills SA2 is expected to increase by 1,161 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of approximately 6.0% in total over the 17 years.

Recent residential development output has been above average within West Pennant Hills when compared nationally

West Pennant Hills averaged approximately 94 new dwelling approvals per year based on AreaSearch analysis of ABS building approval numbers. Around 473 homes were approved between financial years FY-21 and FY-25, with an additional 40 approved in FY-26 so far. The population has declined recently, suggesting that new supply has been meeting demand, offering buyers good choice.

New homes are being built at an average expected construction cost value of $702,000, indicating a focus on the premium market with high-end developments. This financial year, $4.2 million in commercial development approvals have been recorded, reflecting the area's residential character. Recent construction comprises 41.0% detached dwellings and 59.0% medium to high-density housing, creating more affordable entry points for downsizers, investors, and first-home buyers. This shift contrasts with the existing housing stock, which is currently 91.0% houses, suggesting decreasing availability of developable sites and changing lifestyles requiring diverse housing options.

West Pennant Hills has a low density characteristic, with around 82 people per dwelling approval. According to AreaSearch's latest quarterly estimate, the area is expected to grow by approximately 1,003 residents through to 2041. With current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers and potentially enabling growth that exceeds current forecasts.
