Rossmoyne

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

As of Nov 2025, the estimated population for the Rossmoyne statistical area (Lv2) is around 4,197. This reflects a growth of 559 people since the 2021 Census, which reported a population of 3,638. The increase was inferred from AreaSearch's estimation of the resident population at 3,878 following examination of ABS's latest ERP data release in June 2024 and an additional 80 validated new addresses since the Census date. This results in a population density ratio of 2,559 persons per square kilometer, placing Rossmoyne (SA2) in the upper quartile relative to national locations assessed by AreaSearch. The area's growth rate of 15.4% since the 2021 census exceeded both the national average (9.7%) and state average. Overseas migration was the primary driver of population growth during this period.

AreaSearch is using ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data and post-2032 estimations, AreaSearch utilises the growth rates by age cohort provided by the ABS in its latest Greater Capital Region projections, released in 2023 based on 2022 data. Future population dynamics forecast a significant increase for Rossmoyne (SA2), with an expected rise of 1,003 persons to reach 5,197 by 2041, reflecting an 18.6% total increase over the 17-year period.

AreaSearch assessment of residential approval activity sees Rossmoyne among the top 30% of areas assessed nationwide

AreaSearch analysis of ABS building approval numbers shows Rossmoyne averaged approximately 36 new dwelling approvals per year over the past five financial years, totalling an estimated 181 homes. As of FY26, 14 approvals have been recorded. Each dwelling built has resulted in an average of 2.2 new residents per year between FY21 and FY25. The average construction cost value for new homes is $610,000, indicating a focus on the premium market with high-end developments.

This financial year, commercial development approvals totalled $634,000, suggesting minimal commercial development activity in Rossmoyne compared to Greater Perth, where building activity per person is 88.0% higher. The area's new building activity comprises 96.0% standalone homes and 4.0% attached dwellings, maintaining its traditional suburban character with a focus on family homes. Despite the current mix of houses at 79.0%, developers are building more traditional houses, suggesting strong demand for family homes despite density pressures. Rossmoyne has approximately 133 people per dwelling approval, indicating an expanding market.

By 2041, AreaSearch estimates Rossmoyne's population will grow by 781 residents. At current development rates, new housing supply should meet demand comfortably, providing favourable conditions for buyers and potentially supporting growth beyond current projections.

Employment opportunities appear limited locally based on Census data comparing working population to resident population. Over the 12 months to September 2025, employment increased by 2.5% while labour force increased by 2.3%, reducing the unemployment rate by 0.3 percentage points. State-level data as of 25-Nov shows WA employment contracted by 0.27% (losing 5,520 jobs), with the state unemployment rate at 4.6%. National employment forecasts from May-25 project national employment growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Rossmoyne's employment mix suggests local employment should increase by 6.9% over five years and 14.3% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not account for localised population projections.
