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 Feb 2026, the estimated population of the suburb of St Helens Park is around 7,209. This reflects an increase since the 2021 Census, which reported a population of 6,647 people. The increase of 562 people (8.5%) was inferred from AreaSearch's estimate of the resident population at 6,985 following examination of the latest ERP data release by the ABS in June 2024 and an additional 8 validated new addresses since the Census date. This level of population equates to a density ratio of 1,397 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. The suburb's growth rate of 8.5% since the 2021 census exceeded the state's growth rate of 7.8%. Natural growth contributed 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. For areas not covered by this data, AreaSearch utilises the NSW State Government's SA2 level projections, 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 lower quartile growth, with the suburb expected to increase by 376 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of 0.5% in total over the 17 years.

Development
Residential development activity is slightly higher than average within St Helens Park when compared nationally
Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, St Helens Park has experienced around 37 dwellings receiving development approval per year over the past five financial years ending June 2025. This totals an estimated 188 homes. So far in the financial year 2026 (FY-26), 10 approvals have been recorded. Over these five years, there has been an average of 0.8 new residents per year per dwelling constructed.
The supply of dwellings is meeting or surpassing demand, providing greater buyer choice and potentially supporting population growth above projections. The average construction value for new dwellings over this period was $364,000. There have also been $1.1 million in commercial approvals recorded during FY-26, indicating the area's residential nature.
Compared to Greater Sydney, St Helens Park shows 16.0% lower construction activity per person while it ranks among the 84th percentile of areas assessed nationally. However, construction activity has intensified recently. The new building activity comprises 74.0% detached dwellings and 26.0% medium and high-density housing, sustaining the area's suburban identity with a concentration of family homes suited to buyers seeking space. There are approximately 117 people per dwelling approval in St Helens Park, indicating an expanding market. Looking ahead, based on the latest AreaSearch quarterly estimate, St Helens Park is expected to grow by 33 residents through to 2041. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.

Employment
St Helens Park shows employment indicators that trail behind approximately 70% of regions assessed across Australia
St Helens Park has a diverse workforce with both white and blue collar jobs represented. Essential services sectors are well-represented in the area. As of September 2025, the unemployment rate is 7.8%, with an estimated employment growth of 5.5% over the past year.
This data was aggregated from statistical areas by AreaSearch. There are currently 3,557 residents employed while the unemployment rate is 3.6% higher than Greater Sydney's rate of 4.2%. Workforce participation in St Helens Park is similar to Greater Sydney's at 70.0%. A significant portion of residents, 27.8%, work from home according to Census responses, which may have been influenced by Covid-19 lockdowns.
The primary industries for employment among residents are health care & social assistance, retail trade, and construction. St Helens Park shows a strong specialization in manufacturing, with an employment share of 1.6 times the regional level. However, professional & technical services are under-represented at 3.8%, compared to Greater Sydney's 11.5%. The area appears to offer limited local employment opportunities based on Census data comparing working population and resident population. Between September 2024 and September 2025, employment levels increased by 5.5% while the labour force also grew by 5.5%, keeping unemployment relatively stable. In contrast, Greater Sydney experienced employment growth of 2.1% and labour force growth of 2.4%, with a slight increase in unemployment. Jobs and Skills Australia's national employment forecasts from May-25 provide insights into potential future demand within St Helens Park. These projections suggest that national employment will expand by 6.6% over five years and 13.7% over ten years, but growth rates vary significantly between industry sectors. Applying these projections to St Helens Park's current employment mix indicates local employment should increase by 6.1% over five years and 13.0% over ten years. However, it is important to note that this extrapolation does not take into account localised population projections.
