Plumpton (NSW)

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

As of Nov 2025, the estimated population of the suburb of Plumpton (NSW) is around 10,138, reflecting an increase of 68 people since the 2021 Census. This growth represents a 0.7% rise from the previous population count of 10,070. The change is inferred from AreaSearch's estimation of the resident population at 10,077 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 results in a density ratio of 3,425 persons per square kilometer, placing Plumpton in the upper quartile relative to national locations assessed by AreaSearch. The suburb's 0.7% growth since census is within 2.4 percentage points of the SA3 area (3.1%), indicating competitive growth fundamentals. Overseas migration contributed approximately 53.0% of overall population gains during recent periods, driving primary population growth in the area.

AreaSearch adopts 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 from these aggregations are applied to all areas for years 2032 to 2041. Over this period, projections indicate a decline in overall population, with the suburb's population expected to shrink by 329 persons by 2041. However, growth across specific age cohorts is anticipated, led by the 75 to 84 age group, which is projected to expand by 600 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 received around 17 dwelling approvals per year over the past five financial years, totalling an estimated 88 homes. As of FY-26, there have been 9 recorded approvals. The area's population decline has not significantly impacted development activity. New dwellings are approved at an average construction cost value of $254,000, below regional norms, indicating more affordable housing options.

This financial year, Plumpton has seen $636,000 in commercial development approvals, reflecting its residential nature. Compared to Greater Sydney and nationally, Plumpton shows lower construction activity per person, ranking among the 28th percentile of areas assessed. This results in relatively constrained buyer choice, supporting interest in existing properties. Recent construction comprises 95.0% standalone homes and 5.0% medium and high-density housing, sustaining the area's suburban identity with a concentration of family homes suited to buyers seeking space.

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.

Jobs and Skills Australia's national employment forecasts from Sep-22 project national employment growth at 6.6% over five years and 13.7% over ten years, with varying rates between industry sectors. Applying these projections to Plumpton's employment mix suggests local employment should increase by 6.3% over five years and 13.4% over ten years.
