Mosman

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

Based on analysis of ABS population updates for Mosman, and new addresses validated by AreaSearch since the 2021 Census, the suburb's estimated population is around 29,266 as of November 2025. This reflects an increase of 937 people (3.3%) compared to the 2021 Census figure of 28,329. The change is inferred from AreaSearch's estimate of Mosman's resident population at 29,253 following examination of the latest ERP data release by the ABS in June 2024, along with an additional 33 validated new addresses since the Census date. This level of population equates to a density ratio of 3,383 persons per square kilometer, placing Mosman in the upper quartile relative to national locations assessed by AreaSearch. The suburb's 3.3% growth since census is within 2.1 percentage points of the SA4 region (5.4%), demonstrating competitive growth fundamentals. Population growth for Mosman was primarily driven by overseas migration contributing approximately 90.0% of overall population gains during recent periods.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022, and NSW State Government's SA2 level projections for areas not covered by this data, released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to Mosman for years 2032 to 2041. Projections indicate a decline in overall population over this period, with the suburb's population expected to contract by 505 persons by 2041 according to this methodology. 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.

AreaSearch assessment of residential development drivers sees a low level of activity in Mosman, placing the area among the bottom 25% of areas assessed nationally

Mosman has recorded approximately 53 residential properties granted approval annually. Between financial years FY21 and FY25, around 267 homes were approved, with an additional 14 approved so far in FY26. This new supply likely kept up with demand despite population decline, offering good choice to buyers.

The average construction value of these properties was $2,095,000, indicating a focus on the premium segment. In FY26, Mosman has seen $14.8 million in commercial approvals, demonstrating moderate levels of commercial development compared to Greater Sydney. Nationally, Mosman places among the 43rd percentile of areas assessed for construction activity, suggesting limited choices for buyers and supporting demand for existing properties. Recent construction comprises 37.0% detached dwellings and 63.0% medium and high-density housing, creating more affordable entry points for downsizers, investors, and first-home buyers. With around 386 people per approval, Mosman indicates a mature market.

Given the expected stable or declining population, pressure on housing is likely to remain reduced, potentially presenting opportunities for buyers.
