Rossmore (NSW)

An assessment of population growth drivers in Rossmore reveals an overall ranking slightly below national averages considering recent, and medium term trends

Based on ABS population updates and AreaSearch validation, the suburb of Rossmore (NSW) had an estimated population of around 2,789 as of Feb 2026. This reflects a growth of 548 people since the 2021 Census, which reported a population of 2,241. The increase is inferred from AreaSearch's estimate of 2,102 residents in Jun 2024, following examination of ABS ERP data and address validation since the Census date. This results in a population density ratio of 170 persons per square kilometer. Rossmore's growth rate of 24.5% since the 2021 census exceeded the state average of 7.8%. Population growth was primarily driven by interstate migration, contributing approximately 83.0% of overall gains.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022, and NSW State Government's SA2 level projections where data is not available, released in 2022 with a base year of 2021. Growth rates by age group are applied to all areas for years 2032 to 2041. According to these projections, the suburb is predicted to grow exceptionally, placing it in the top 10 percent nationally, with an expected increase of 8,183 persons to 2041, reflecting a total increase of 314.8% over the 17 years.

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

Based on AreaSearch analysis of ABS building approval numbers, Rossmore averaged approximately 8 new dwelling approvals annually over the past five financial years, totalling an estimated 44 homes. So far in FY26, 13 approvals have been recorded. On average, around 35.7 new residents arrived per year for each dwelling constructed between FY21 and FY25, indicating significant demand exceeding supply, which typically leads to price growth and increased buyer competition. The average construction value of these dwellings was approximately $480,000, suggesting a focus on the premium segment with upmarket properties.

This financial year has seen $154,000 in commercial development approvals, reflecting the area's residential nature. Compared to Greater Sydney, Rossmore records notably lower building activity, at 82.0% below the regional average per person. This scarcity of new homes usually strengthens demand and prices for existing properties. The current level is also below national averages, potentially indicating planning constraints or market maturity. Recent building activity consists entirely of detached houses, preserving Rossmore's low-density nature and appealing to space-seeking buyers with around 301 people per dwelling approval.

Looking ahead, Rossmore is projected to grow by approximately 8,781 residents by 2041, according to the latest AreaSearch quarterly estimate. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing buyer competition and supporting stronger price growth.

Limited local employment opportunities are suggested by Census data comparing working population to resident population. Between September 2024 and September 2025, employment levels increased by 5.0%, labour force by 5.4%, raising the unemployment rate by 0.3 percentage points (AreaSearch analysis). In Greater Sydney, employment grew by 2.1% with a 0.2 percentage point rise in unemployment. Jobs and Skills Australia's national employment forecasts from May-25 project overall growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Rossmore's employment mix suggests local employment could increase by 5.7% over five years and 11.8% over ten years, though this is a simplified extrapolation for illustrative purposes.
