Gwynneville

Population growth drivers in Gwynneville are strong compared to national averages based on AreaSearch's ranking of recent, and medium to long-term trends

As of November 2025, Gwynneville's population is estimated at around 3,388 people. This reflects an increase of 249 people since the 2021 Census, which reported a population of 3,139 people. The change was inferred from AreaSearch's estimation of the resident population at 3,375 based on examination of the latest ERP data release by ABS in June 2024, along with an additional 11 validated new addresses since the Census date. This level of population results in a density ratio of 2,688 persons per square kilometer, placing Gwynneville in the upper quartile relative to national locations assessed by AreaSearch. Gwynneville's growth rate of 7.9% since the 2021 census exceeded that of both its SA3 area (4.0%) and the non-metro area, marking it as a growth leader in the region. Overseas migration contributed 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, and NSW State Government's SA2 level projections where data was not available, released in 2022 with 2021 as the base year. Considering these projections, Gwynneville is forecast to increase by 1,164 persons by 2041, reflecting a total increase of 33.1% over the 17 years.

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

Gwynneville averaged approximately 12 new dwelling approvals per year over the past five financial years, totalling an estimated 63 homes. As of FY-26, one approval has been recorded. The average number of new residents per year per dwelling constructed was 1.6 between FY-21 and FY-25, indicating balanced supply and demand conditions. However, this figure increased to 6.7 people per dwelling over the past two financial years, reflecting Gwynneville's growing popularity and potential supply constraints. New homes are being built at an average expected construction cost of $580,000, which is higher than regional norms, suggesting quality-focused development.

In FY-26, $2.7 million in commercial approvals have been registered, demonstrating the area's primarily residential nature. Compared to Rest of NSW, Gwynneville has around two-thirds the rate of new dwelling approvals per person and ranks among the 52nd percentile nationally. Recent construction comprises 31.0% detached houses and 69.0% medium and high-density housing, marking a significant shift from existing housing patterns (currently 58.0% houses). This trend may indicate diminishing developable land availability and responds to evolving lifestyle preferences and housing affordability needs. Gwynneville has approximately 316 people per dwelling approval, suggesting potential for growth.

According to the latest AreaSearch quarterly estimate, Gwynneville is expected to grow by 1,122 residents through to 2041. If current construction levels persist, housing supply may lag population growth, potentially intensifying buyer competition and supporting price growth.
