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, Plumpton's population is estimated at around 10,308 as of Nov 2025. This reflects an increase of 238 people (2.4%) since the 2021 Census, which reported a population of 10,070 people. The change is inferred from the resident population of 10,107 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 26 validated new addresses since the Census date. This level of population equates to a density ratio of 3,482 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Plumpton's 2.4% growth since census positions it within 2.8 percentage points of the SA3 area (5.2%), demonstrating competitive growth fundamentals. Population growth for the area 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. Over this period, projections indicate a decline in overall population, with the Plumpton (NSW) statistical area (Lv2)'s population expected to reduce by 294 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 grow by 605 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

Plumpton has averaged approximately 16 new dwelling approvals per year over the past five financial years ending June 2021. This totals an estimated 84 homes. In the current financial year, FY-26, 11 approvals have been recorded as of now. The area's population decline suggests that the new supply has likely kept pace with demand, offering buyers good choices while providing more affordable housing options, with new homes valued at around $254,000 on average, below the regional average.

This financial year has seen $949,000 in commercial approvals registered, indicating minimal commercial development activity. Compared to Greater Sydney, Plumpton has about two-thirds the rate of new dwelling approvals per person and ranks among the 28th percentile nationally, suggesting limited buyer options but strengthening demand for established properties. This lower-than-national-average activity reflects market maturity and possible development constraints. Recent development in Plumpton has been entirely detached houses, maintaining its traditional suburban character with a focus on family homes appealing to those seeking space.

Interestingly, developers are building more traditional houses than the current mix suggests (82.0% at Census), indicating continued strong demand for family homes despite density pressures. The location has approximately 580 people per dwelling approval, demonstrating an established market. With population expected to remain stable or decline, Plumpton should see reduced pressure on housing, potentially creating opportunities for buyers in the future.
