Mosman

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

The population of the Mosman statistical area (Lv2) is estimated at around 29,298 as of November 2025. This reflects an increase of 969 people since the 2021 Census, which reported a population of 28,329 people. The change was inferred from the resident population of 29,253 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 33 validated new addresses since the Census date. This level of population equates to a density ratio of 3,387 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Mosman's growth of 3.4% since census positions it within 2.0 percentage points of the SA3 area (5.4%), demonstrating competitive growth fundamentals. Population growth was primarily driven by overseas migration that contributed 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 areas not covered by this data, AreaSearch utilises 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 applied to all areas for years 2032 to 2041. Over this period, projections indicate a decline in overall population, with the Mosman (SA2) population expected to contract by 505 persons by 2041. However, growth across specific age cohorts is anticipated, led by the 85 and over age group, which is projected to grow by 1,322 people.

By FY-26, 17 approvals have been recorded so far. Mosman has experienced population decline, with new supply likely keeping up with demand, offering good choice to buyers. The average expected construction cost value of new dwellings is $2,095,000, indicating a focus on the premium market with high-end developments.

Compared to Greater Sydney, Mosman records 12.0% less building activity per person and places among the 43rd percentile of areas assessed nationally, offering more limited choices for buyers and supporting demand for existing homes. Building activity has accelerated in recent years, reflecting market maturity and possible development constraints. New development consists of 37.0% detached houses and 63.0% attached dwellings, skewing towards compact living which offers affordable entry pathways attracting downsizers, investors, and first-time purchasers. Mosman indicates a mature market with around 386 people per approval.

In contrast, Greater Sydney experienced employment growth of 2.1% and labour force growth of 2.4%.

National employment forecasts from Jobs and Skills Australia project a 6.6% increase over five years and 13.7% over ten years. Applying these projections to Mosman's employment mix suggests local employment should grow by 7.6% over five years and 15.0% over ten years, though this is a simple extrapolation for illustrative purposes and does not account for localized population projections.
