Seaholme

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

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch, the suburb of Seaholme's population is estimated at around 2,283 as of Feb 2026. This reflects an increase of 216 people (10.4%) since the 2021 Census, which reported a population of 2,067 people. The change is inferred from the resident population of 2,228, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024, and an additional 7 validated new addresses since the Census date. This level of population equates to a density ratio of 2,403 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Seaholme's 10.4% growth since the 2021 census exceeded the national average (9.9%), marking it as a growth leader in the region. Population growth for the area was primarily driven by overseas migration that contributed approximately 76.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For any SA2 areas not covered by this data, AreaSearch utilises the VIC State Government's Regional/LGA projections released in 2023 with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Growth rates by age group from these aggregations are also applied across all areas for years 2032 to 2041. Moving forward, an above median population growth of statistical areas analysed by AreaSearch is projected, with the suburb expected to grow by 322 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 9.9% in total over the 17 years.

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 35th percentile 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.
