Mosman - South

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

Based on AreaSearch's analysis, Mosman - South's population is around 14,906 as of Feb 2026. This reflects an increase of 341 people (2.3%) since the 2021 Census, which reported a population of 14,565 people.

This population level equates to a density ratio of 2,775 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Population growth for the area was primarily driven by overseas migration, which contributed approximately 87.8% of overall population gains during recent periods.

AreaSearch adopts 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 utilizes the 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 also applied to all areas for years 2032 to 2041. Regarding demographic trends, projections indicate a decline in overall population, with the area's population expected to shrink by 458 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 increase by 636 people. See the age section for more details.

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

Mosman - South has seen around 23 new homes approved per year, totalling 118 homes over the past 5 financial years. So far in FY-26, 9 approvals have been recorded. Given population has fallen over the past period, development activity has been adequate in relative terms, which is a positive for buyers, while new homes are being built at an average value of $1,151,000, showing that developers are focusing on the premium market with high-end developments. Additionally, $13.5 million in commercial approvals have been registered this financial year, demonstrating moderate levels of commercial development.

Compared to Greater Sydney, Mosman - South shows approximately 75% of the construction activity per person and places within the 29th percentile of areas assessed nationally, meaning more limited choices for buyers and supporting demand for existing dwellings. This activity is below the national average, indicating the area's established nature and suggesting potential planning limitations. Recent construction comprises 41.0% standalone homes and 59.0% attached dwellings. This skew toward compact living offers affordable entry pathways and attracts downsizers, investors, and first-time purchasers. The location has approximately 593 people per dwelling approval, demonstrating an established market.

With population projections showing stability or decline, Mosman - South should see reduced housing demand pressures, benefiting potential buyers.
