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 May 2026, the population of the suburb of Rossmore (NSW) is estimated at around 2,634 people. This figure reflects a growth of 393 people since the 2021 Census, which reported a population of 2,241 people. The increase is inferred from AreaSearch's estimation of the resident population at 2,225 following examination of the latest ERP data release by the ABS in June 2025, along with an additional 1 validated new address since the Census date. This results in a population density ratio of 161 persons per square kilometer. The suburb's growth rate of 17.5% since the 2021 census exceeded both the state average of 7.1% and the Greater Sydney average, indicating significant growth. Interstate migration contributed approximately 83.0% of overall population gains during recent periods, with natural growth and overseas migration also being positive factors.

AreaSearch's projections for Rossmore are based on ABS/Geoscience Australia data released in 2024 using a base year of 2022, and NSW State Government SA2-level projections released in 2022 using a base year of 2021 for areas not covered by the former. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. By 2041, Rossmore is projected to grow by 2,679 persons, reflecting an increase of 86.2% in total over the 16-year period, placing it in the top 10 percent of national areas for growth.

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 indicates Rossmore has averaged approximately 10 new dwelling approvals annually over the past five financial years, totalling around 50 homes. In FY26 so far, 20 approvals have been recorded. This averages to about 0.3 new residents per year arriving per new home between FY21 and FY25, suggesting new construction is meeting or exceeding demand. The average value of new properties constructed is $471,000, indicating a focus on the premium segment.

Additionally, $154,000 in commercial development approvals have been recorded this financial year, reflecting Rossmore's residential nature. Compared to Greater Sydney, Rossmore has lower building activity, with 76.0% fewer approvals per person. This scarcity can strengthen demand and prices for existing properties, although recent construction activity has increased. All developments so far have been standalone homes, preserving the area's low-density character and attracting space-seeking buyers, with around 169 people per dwelling approval.

By 2041, Rossmore is projected to grow by approximately 2,270 residents. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth.
