Plumpton (NSW)

Population growth drivers in Plumpton are slightly above average based on AreaSearch's ranking of recent, and medium term trends

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch since the Census, Plumpton's population is estimated at around 10,206 as of May 2026. This reflects an increase of 136 people (1.4%) since the 2021 Census, which reported a population of 10,070 people. The change is inferred from the resident population of 10,188 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2025 and an additional 28 validated new addresses since the Census date. This level of population equates to a density ratio of 3,448 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Over the past decade, Plumpton has demonstrated resilient growth patterns with a compound annual growth rate of 0.9%, outpacing the SA3 area. Population growth for the suburb was primarily driven by overseas migration that contributed approximately 53.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, AreaSearch is utilising the NSW State Government's SA2 level projections, as released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are also applied to all areas for years 2032 to 2041. As we examine future population trends, projections indicate a decline in overall population, with the suburb's population expected to shrink by 262 persons by 2041 according to this methodology. However, growth across specific age cohorts is anticipated, led by the 75 to 84 age group, which is projected to expand by 583 people.

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

Based on AreaSearch analysis using ABS building approval data, Plumpton has seen approximately 16 new homes approved annually. Between financial years FY-21 to FY-25, around 84 homes were approved, with 17 more approved in FY-26 so far. Despite population decline, new supply has likely met demand, offering buyers good choice.

Average dwelling value is $254,000, under regional levels, indicating accessible housing choices. Commercial approvals totalled $949,000 in FY-26, suggesting minimal commercial development activity. Compared to Greater Sydney, Plumpton records 64% of building activity per person and ranks at the 28th percentile nationally, implying limited buyer choices, supporting demand for existing homes. This activity reflects the area's maturity and possible planning constraints.

New construction consists solely of detached houses, maintaining Plumpton's suburban character with a focus on family homes. Developers are building more traditional houses than current mix suggests, indicating strong demand for family homes despite density pressures. With around 577 people per dwelling approval, Plumpton reflects a highly mature market. Population projections showing stability or decline suggest reduced housing demand pressures, benefiting potential buyers.
