Gwynneville

Population growth drivers in Gwynneville are above average based on AreaSearch's ranking of recent, and medium to long-term trends

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch since the Census, Gwynneville's estimated population is around 3,407 as of Nov 2025. This reflects an increase of 268 people (8.5%) since the 2021 Census, which reported a population of 3,139 people. The change is inferred from the resident population of 3,360 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 11 validated new addresses since the Census date. Gwynneville's population equates to a density ratio of 2,704 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Gwynneville's growth since the 2021 census exceeded the SA3 area (4.4%) and the non-metro area, marking it as a growth leader in the region. Population growth was primarily driven by overseas migration contributing approximately 86.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections released in 2022 with 2021 as the base year. Growth rates by age group are applied to all areas for years 2032 to 2041. Considering projected demographic shifts, a significant population increase is forecast for Gwynneville (SA2), expected to increase by 1,122 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 31.1% in total over the 17 years.

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

AreaSearch analysis of ABS building approval numbers shows Gwynneville averaged around 14 new dwelling approvals each year over the past five financial years, totalling an estimated 71 homes. As of FY-26, four approvals have been recorded. Historically, the area has seen an average of 1.4 new residents per year per dwelling constructed between FY-21 and FY-25, indicating balanced supply and demand with stable market conditions. However, recent data shows this ratio has increased to 9.3 people per dwelling over the past two financial years, suggesting growing popularity and potential supply constraints. New homes are being built at an average construction cost of $579,000, reflecting a focus on premium segment properties.

This year, $9.5 million in commercial approvals have been registered, indicating moderate levels of commercial development compared to the rest of NSW. Gwynneville has around three-quarters the rate of new dwelling approvals per person and ranks among the 39th percentile nationally, suggesting limited housing choices for buyers and supporting demand for existing dwellings. Recent construction comprises 31% detached houses and 69% medium and high-density housing, marking a shift from the current 58% house-dominated pattern. This trend may be due to diminishing developable land availability and evolving lifestyle preferences. Gwynneville's population density is approximately 442 people per dwelling approval, reflecting an established area.

By 2041, AreaSearch estimates the location will grow by 1,061 residents. If current construction levels persist, housing supply may lag behind population growth, potentially intensifying buyer competition and underpinning price growth.
