Rossmore (NSW)

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

As of Nov 2025, Rossmore's population is estimated at around 2,230 people. This reflects a decrease from the 2021 Census figure of 2,241 people, a change inferred from AreaSearch's resident population estimate of 2,006 based on latest ERP data release by ABS (June 2024) and address validation since the Census date. This equates to a density ratio of 136 persons per square kilometer. Over the past decade, Rossmore demonstrated resilient growth patterns with a compound annual growth rate of 7.9%, outpacing its SA3 area. Population growth was primarily driven by interstate migration contributing approximately 83.0% of overall population gains during recent periods, although all drivers including natural growth and overseas migration were positive factors. AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022.

For areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Looking ahead, exceptional growth is predicted over the period with the suburb expected to grow by 8,370 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 427.2% in total over the 17 years.

Residential development activity is lower than average in Rossmore according to AreaSearch's national comparison of local real estate markets

AreaSearch analysis of ABS building approval numbers shows Rossmore averaged around 2 new dwelling approvals annually over the past five financial years, totalling an estimated 13 homes. So far in FY-26, 2 approvals have been recorded. Between FY-21 and FY-25, an average of 120.9 new residents arrived per year per dwelling constructed.

This high demand coupled with limited supply typically results in price growth and increased buyer competition, while new properties are constructed at an average value of $523,000. Compared to Greater Sydney, Rossmore has substantially reduced construction levels, supporting stronger demand and values for established homes. Nationally, it is lower, reflecting market maturity and possible development constraints. Recent development in Rossmore has been entirely comprised of detached houses, maintaining its traditional low density character with a focus on family homes appealing to those seeking space. The estimated count of 902 people per dwelling approval reflects its quiet, low activity development environment.

Looking ahead, Rossmore is expected to grow by 9,526 residents through to 2041, according to the latest AreaSearch quarterly estimate. Should current construction levels persist, housing supply could lag population growth, likely intensifying buyer competition and underpinning price growth.
