Seaholme

Population growth drivers in Seaholme are above average based on AreaSearch's ranking of recent, and medium to long-term trends

Based on ABS population updates and AreaSearch validations, as of November 2025, Seaholme's estimated population is around 2,274. This reflects a growth of 207 people since the 2021 Census, which reported a population of 2,067. The increase is inferred from AreaSearch's resident population estimate of 2,228 in June 2024, derived from ABS's latest ERP data release, and an additional 7 validated new addresses since the Census date. This results in a density ratio of 2,393 persons per square kilometer, placing Seaholme in the upper quartile nationally according to AreaSearch assessments. The area's 10.0% growth exceeds the national average (9.7%), indicating it as a growth leader in the region. Overseas migration contributed approximately 76.0% of overall population gains recently.

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, it employs 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. Projecting forward with demographic trends, an above median population growth is expected in the Seaholme statistical area (Lv2), with a projected increase of 323 persons by 2041, reflecting a total increase of 10.1% over the 17 years.

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

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Seaholme has recorded around 15 residential properties granted approval per year over the past five financial years. This totals an estimated 78 homes. So far in FY-26, six approvals have been recorded. On average, only 0.7 people moved to the area for each dwelling built between FY-21 and FY-25, indicating that new supply is keeping pace with or exceeding demand.

The average construction cost value of new homes over this period was $602,000, suggesting developers are targeting the premium market segment with higher-end properties. In terms of commercial activity, Seaholme has registered $53.6 million in approvals this financial year. When compared to Greater Melbourne, Seaholme records about three-quarters the building activity per person and places among the 35th percentile of areas assessed nationally, resulting in relatively constrained buyer choice and supporting interest in existing dwellings. New building activity shows 32.0% standalone homes and 68.0% townhouses or apartments, reflecting a focus on higher-density living to create more affordable entry points for downsizers, investors, and first-home buyers. This represents a considerable change from the current housing mix of 81.0% houses.

The location has approximately 479 people per dwelling approval, indicating an established area. Looking ahead, Seaholme is expected to grow by 230 residents through to 2041, as estimated in the latest AreaSearch quarterly report. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
