Mosman

Mosman has shown very soft population growth performance across periods assessed by AreaSearch

Based on analysis of ABS population updates for the broader area and new addresses validated by AreaSearch, as of Feb 2026 the estimated population of Mosman is around 29,341. This reflects an increase of 1,012 people since the 2021 Census, which reported a population of 28,329. The change is inferred from AreaSearch's resident population estimate of 29,253 following examination of the latest ERP data release by the ABS in Jun 2024 and an additional 62 validated new addresses since the Census date. This level of population equates to a density ratio of 3,392 persons per square kilometer, placing Mosman in the upper quartile relative to national locations assessed by AreaSearch. Mosman's 3.6% growth since census positions it within 2.0 percentage points of the SA3 area (5.6%), demonstrating competitive growth fundamentals. Population growth for the suburb was primarily driven by overseas migration, contributing approximately 90.0% of overall population gains 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 any SA2 areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections, as released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Over this period, projections indicate a decline in overall population of Mosman, expected to contract by 515 persons by 2041 according to this methodology. However, growth across specific age cohorts is anticipated, led by the 85 and over age group, projected to grow by 1,339 people.
