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 analysis of ABS population updates, the Rossmore (NSW) statistical area (Lv2)'s population is estimated at around 2,723 as of Nov 2025. This reflects an increase of 482 people (21.5%) since the 2021 Census, which reported a population of 2,241 people. The change is inferred from the resident population of 2,102, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and address validation since the Census date. This level of population equates to a density ratio of 166 persons per square kilometer. The Rossmore (NSW) (SA2)'s 21.5% growth since the 2021 census exceeded the state's 7.6%, marking it as a growth leader in the region. Population growth for the area was primarily driven by interstate migration, contributing approximately 83.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, 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, 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. Looking at population projections moving forward, exceptional growth, placing it in the top 10 percent of national areas, is predicted over this period with the area expected to grow by 8,200 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 325.5% in total over the 17 years.

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

AreaSearch analysis of ABS building approval numbers allocated from statistical area data shows Rossmore averaged around 8 new dwelling approvals annually over the past 5 financial years up to FY26, totalling an estimated 44 homes. So far in FY26, 13 approvals have been recorded. Based on data from FY21 to FY25, there is an average of 35.7 new residents arriving per year per dwelling constructed, indicating demand significantly exceeds supply. New properties are constructed at an average expected cost of $480,000, suggesting a focus on the premium segment with upmarket properties.

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

According to AreaSearch's latest quarterly estimate, Rossmore is expected to grow by 8,863 residents through to 2041. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing buyer competition and supporting stronger price growth.
