St Helens Park

St Helens Park 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 ABS population updates and new addresses validated by AreaSearch, as of Nov 2025, St Helens Park's estimated population is around 7,183. This reflects an increase of 536 people since the 2021 Census, which reported a population of 6,647. The change is inferred from AreaSearch's resident population estimate of 6,978 following examination of ABS's ERP data release in Jun 2024 and additional validated new addresses since the Census date. This level of population equates to a density ratio of 1,392 persons per square kilometer, above the average seen across national locations assessed by AreaSearch. St Helens Park's growth rate of 8.1% since the 2021 census exceeded the state's rate of 7.6%. Population growth was primarily driven by natural growth contributing approximately 59.0% 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. Future population trends indicate an increase just below the median of statistical areas analysed by AreaSearch, with the area expected to increase by 385 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of approximately 0.9% in total over the 17 years.

Residential development activity is slightly higher than average within St Helens Park when compared nationally

St Helens Park averaged approximately 37 new dwelling approvals annually. Between FY-21 and FY-25, around 188 homes were approved, with an additional 10 approved in FY-26 to date. On average, each new dwelling constructed over the past five financial years has accommodated 0.8 new residents per year.

This indicates that supply is meeting or exceeding demand, offering greater buyer choice and supporting potential population growth above projections. The average construction cost value of new dwellings is $364,000. In FY-26, there have been $1.1 million in commercial approvals, suggesting minimal commercial development activity compared to previous years.

Compared to Greater Sydney, St Helens Park has seen 16.0% less new development per person. However, it ranks among the 84th percentile of areas assessed nationally. Building activity has accelerated in recent years. The area's new development consists of 74.0% detached dwellings and 26.0% medium and high-density housing, maintaining its traditional suburban character with a focus on family homes. With approximately 117 people per approval, St Helens Park reflects an area experiencing growth and development. According to the latest AreaSearch quarterly estimate, the area is expected to grow by 66 residents through to 2041. Given current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.
