Winston Hills' population, as of August 2025, is approximately 11,210. This figure represents an increase of 11 people since the 2021 Census, which recorded a population of 11,199. The change is inferred from the estimated resident population of 11,207 in June 2024 and an additional 11 validated new addresses since the Census date.

Overseas migration contributed approximately 82.5% of overall population gains during recent periods.

AreaSearch uses 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 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 the years 2032 to 2041. Future population trends indicate an increase just below the median of national areas, with Winston Hills expected to expand by 811 persons to 2041 based on the latest population numbers, reflecting a total increase of 7.2% over the 17 years.

AreaSearch assessment of residential development drivers sees a low level of activity in Winston Hills, placing the area among the bottom 25% of areas assessed nationally

In terms of commercial development, $2.2 million in approvals have been recorded this financial year, indicating minimal activity. Compared to Greater Sydney, Winston Hills has significantly less development activity, 61.0% below the regional average per person. This limited new supply generally supports stronger demand and values for established properties. Nationally, Winston Hills' development activity is also lower, reflecting market maturity and possible development constraints. Recent construction comprises 79.0% standalone homes and 21.0% townhouses or apartments, maintaining the area's traditional suburban character focused on family homes.

With around 390 people per dwelling approval, Winston Hills shows a developed market. Looking ahead, Winston Hills is expected to grow by 808 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.
