AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data and to estimate growth post-2032, AreaSearch utilises the growth rates by age cohort provided by the ABS in its latest Greater Capital Region projections (released in 2023, based on 2022 data). Examining future trends, an above median population growth is projected for the area, with an expected expansion of 1,788 persons to 2041, reflecting a total increase of 13.4% over the 17 years.

AreaSearch assessment of residential development activity positions Mosman Park among the top 25% of areas assessed nationwide

Based on AreaSearch analysis of ABS building approval numbers from statistical area data, Mosman Park has experienced around 42 dwellings receiving development approval annually over the past five financial years, totalling an estimated 214 homes. So far in FY-26, 14 approvals have been recorded. With an average of 4.2 people moving to the area per dwelling built over these five years (FY-21 to FY-25), demand is outpacing supply, which can put upward pressure on prices and increase competition among buyers. New dwellings are developed at an average expected construction cost value of $1,189,000, indicating a focus on the premium segment with upmarket properties.

Additionally, $9.4 million in commercial development approvals have been recorded this financial year, demonstrating moderate levels of commercial development compared to Greater Perth. Mosman Park records 17.0% less building activity per person than Greater Perth and places among the 66th percentile nationally in terms of areas assessed. New building activity shows 36.0% detached dwellings and 64.0% townhouses or apartments, offering affordable entry pathways and attracting downsizers, investors, and first-time purchasers. This represents a considerable change from the current housing mix (currently 62.0% houses), reflecting reduced availability of development sites and addressing shifting lifestyle demands and affordability requirements. With around 211 people per dwelling approval, Mosman Park shows a developing market with population forecasts indicating an addition of 1,427 residents through to 2041 (from the latest AreaSearch quarterly estimate).

Building activity is keeping pace with growth projections, though buyers may experience heightened competition as the population grows.
