Wetherill Park

An assessment of population growth drivers in Wetherill Park reveals an overall ranking slightly below national averages considering recent, and medium term trends

As of Nov 2025, Wetherill Park's population is estimated at around 6,621. This reflects a growth of 209 people since the 2021 Census, which reported a population of 6,412. The change was inferred from AreaSearch's estimation of the resident population at 6,432 following examination of ABS's latest ERP data release (June 2024) and an additional 108 validated new addresses since the Census date. This level of population equates to a density ratio of 590 persons per square kilometer. Wetherill Park's growth rate of 3.3% since the 2021 census exceeded the SA3 area's growth rate of 2.2%. Population growth was primarily driven by overseas migration, contributing approximately 77.0% 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 where applicable, released in 2022 with a base year of 2021. Looking ahead, the suburb is expected to expand by 178 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 2.4% over the 17 years.

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

AreaSearch analysis of ABS building approval numbers shows Wetherill Park had around 28 new homes approved annually over the past 5 financial years, totalling an estimated 144 homes. By FY-26, 6 approvals have been recorded. On average, 1.1 new residents were added per year per dwelling constructed between FY-21 and FY-25, indicating balanced supply and demand. However, recent data shows this rate has increased to 6.2 people per dwelling over the past 2 financial years, suggesting growing popularity and potential undersupply. Development projects averaged $337,000 in construction value, lower than regional levels, offering more affordable housing choices.

In FY-26, there have been $2.1 million in commercial approvals, indicating a predominantly residential focus. Compared to Greater Sydney, Wetherill Park has comparable development activity per person, maintaining market balance with the broader area. New development consists of 57.0% standalone homes and 43.0% attached dwellings, reflecting an increasing blend of housing types offering choices across price ranges. This shift indicates decreasing availability of developable sites and changing lifestyles requiring more diverse, affordable housing options.

The estimated population per dwelling approval is 344 people, reflecting the area's quiet development environment. Population forecasts indicate Wetherill Park will gain 157 residents by 2041. At current development rates, new housing supply should meet demand comfortably, providing good conditions for buyers and potentially supporting growth beyond current projections.
