AreaSearch uses ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch utilises VIC State Government's Regional/LGA projections from 2023, adjusted using weighted aggregation methods to SA2 levels. Growth rates by age group are applied across all areas for years 2032 to 2041. Based on aggregated SA2-level projections, Seaholme is expected to grow by 322 persons to 2041, reflecting an increase of 11.7% over the 17-year period.

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

Seaholme recorded approximately 15 residential properties granted approval per year over the past five financial years from FY-21 to FY-25. This totals an estimated 79 homes. In FY-26, up until now, 6 approvals have been recorded. The average number of people moving to the area for each dwelling built during this period is 0.8 per year.

New supply has kept pace with or exceeded demand, offering ample buyer choice and creating capacity for population growth beyond current forecasts. The average construction cost value of new homes being built is $602,000, indicating developers are targeting the premium market segment with higher-end properties. This financial year, $53.6 million in commercial approvals have been registered, demonstrating high levels of local commercial activity. Compared to Greater Melbourne, Seaholme records about three-quarters the building activity per person and places among the 41st percentile of areas assessed nationally, resulting in relatively constrained buyer choice and supporting interest in existing dwellings. New building activity shows 28.0% standalone homes and 72.0% townhouses or apartments, creating more affordable entry points and suiting downsizers, investors, and first-home buyers.

This reflects a considerable change from the current housing mix of 81.0% houses, due to reduced availability of development sites and shifting lifestyle demands and affordability requirements. The location has approximately 392 people per dwelling approval, reflecting an established area. According to AreaSearch's latest quarterly estimate, Seaholme is expected to grow by 267 residents through to 2041. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.

Greater Melbourne recorded lower growth rates with employment up by 2.4%.
