This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Population
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
As of May 2026, the estimated population of St Helens Park is around 6,596, showing a decrease of 51 people from the 2021 Census figure of 6,647. This decline, representing an 0.8% change, is inferred from AreaSearch's estimation of the resident population at 6,573 following examination of ABS' latest ERP data release in June 2025 and validation of eight new addresses since the Census date. The population density stands at 1,278 persons per square kilometer, exceeding national averages assessed by AreaSearch. Natural growth accounted for approximately 59% of overall population gains during recent periods. AreaSearch's projections for St Helens Park are based on ABS/Geoscience Australia data released in 2024 with a base year of 2022 for covered areas, and NSW State Government's SA2 level projections released in 2022 with a base year of 2021 for uncovered areas.
Growth rates by age group are applied to all areas from 2032 to 2041. According to these projections, the suburb is expected to grow by 298 persons to 2041, reflecting an increase of 4.2% over the 16-year period.

Development
Residential development activity is slightly higher than average within St Helens Park when compared nationally
AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, indicates St Helens Park averaged around 39 new dwelling approvals annually over the past five financial years, totalling an estimated 197 homes. By FY-26 so far, 18 approvals have been recorded. The average population growth per dwelling built in the area was 0.8 people per year between FY-21 and FY-25. This suggests new construction is matching or outpacing demand, offering buyers more options while enabling population growth.
New properties are constructed at an average value of $364,000. There have been $1.1 million in commercial approvals this financial year, indicating a predominantly residential focus. Compared to Greater Sydney, St Helens Park has similar development levels per person, maintaining market balance consistent with the broader area, though construction activity has intensified recently.
New development consists of 75% detached houses and 25% medium and high-density housing, sustaining the area's suburban identity with a concentration of family homes suited to buyers seeking space. With around 114 people per dwelling approval, St Helens Park shows characteristics of a low density area. Population forecasts indicate St Helens Park will gain 275 residents by 2041 (from the latest AreaSearch quarterly estimate). At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
