Rossmoyne

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

As of Nov 2025, Rossmoyne's population is estimated at around 3,921 people. This reflects an increase of 283 people since the 2021 Census, which reported a population of 3,638 people. The change is inferred from AreaSearch's estimation of the resident population at 3,842 following examination of the latest ERP data release by the ABS in June 2024 and an additional 80 validated new addresses since the Census date. This level of population equates to a density ratio of 2,390 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Over the past decade, Rossmoyne has demonstrated resilient growth patterns with a compound annual growth rate of 1.5%, outpacing the SA3 area. Population growth for the suburb was primarily driven by overseas migration 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 areas not covered, AreaSearch utilises growth rates by age cohort provided by the ABS in its latest Greater Capital Region projections (released in 2023, based on 2022 data). Anticipating future population dynamics, a significant increase is forecast for Rossmoyne, with an expected increase of 967 persons to 2041, reflecting an overall increase of 26.0% over the 17 years.

Recent residential development output has been above average within Rossmoyne when compared nationally

Based on AreaSearch analysis of ABS building approval numbers in Rossmoyne from statistical area data, an average of approximately 32 new dwelling approvals per year was recorded over the past five financial years, totalling around 163 homes. Up to May 2026 (FY-26), seven approvals have been recorded so far. On average, each new dwelling built between FY-21 and FY-25 resulted in an increase of approximately 2.4 residents per year, reflecting strong demand which supports property values. The average expected construction cost value for new homes over this period was around $610,000, indicating a focus on the premium market with high-end developments.

In terms of commercial development approvals, $2.0 million has been recorded in FY-26, suggesting minimal commercial development activity to date. Comparatively, Rossmoyne shows 70.0% higher building activity per person when measured against Greater Perth, offering buyers greater choice. However, development activity has moderated in recent periods. The majority of new building activity consists of standalone homes (95.0%), with attached dwellings making up the remaining 5.0%, maintaining the area's traditional suburban character and focus on family homes appealing to those seeking space.

Interestingly, developers are building more traditional houses than the current mix suggests (79.0% at Census), indicating continued strong demand for family homes despite density pressures. The location has approximately 224 people per dwelling approval, suggesting room for growth. According to the latest AreaSearch quarterly estimate, Rossmoyne is expected to grow by 1,021 residents through to 2041. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
