Seaford Meadows

Seaford Meadows lies within the top quartile of areas nationally for population growth performance according to AreaSearch analysis of recent, and medium to long-term trends

Based on ABS population updates for the broader area and new addresses validated by AreaSearch, as of May 2026, the estimated population of Seaford Meadows is around 5,742. This reflects an increase of 640 people (12.5%) since the 2021 Census, which reported a population of 5,102 people. The change is inferred from the resident population of 5,739 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2025 and an additional 202 validated new addresses since the Census date. This level of population equates to a density ratio of 1,612 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. The suburb's 12.5% growth since the 2021 census exceeded the SA3 area (5.8%), along with the SA4 region, marking it as a growth leader in the region. Population growth for Seaford Meadows was primarily driven by overseas migration that contributed approximately 41.0% of overall population gains during recent periods, although all drivers including natural growth and interstate migration were positive factors.

AreaSearch is adopting 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, and for years post-2032, the SA State Government's Regional/LGA projections by age category, released in 2023 and based on 2021 data, are adopted with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Looking at population projections moving forward, a population increase just below the median of national areas is expected, with Seaford Meadows expected to grow by 705 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 12.2% in total over the 16 years.

The level of residential development activity in Seaford Meadows was found to be higher than 90% of real estate markets across the country

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, shows Seaford Meadows recorded approximately 48 residential properties granted approval annually. Over the past five financial years, between FY-21 and FY-25, around 243 homes were approved, with an additional 75 approved so far in FY-26. On average, about 4.5 people moved to the area per year for each dwelling built over these five years, indicating supply is lagging demand, which typically leads to increased buyer competition and pricing pressures.

New properties are constructed at an average expected cost of $380,000, suggesting developers target the premium market segment with higher-end properties. This financial year has seen $1.8 million in commercial development approvals, reflecting a predominantly residential focus compared to Greater Adelaide, where Seaford Meadows records 84.0% more construction activity per person. New building activity comprises approximately 79.0% standalone homes and 21.0% townhouses or apartments, maintaining the area's suburban identity with a concentration of family homes suited for buyers seeking space. With around 90 people per approval, Seaford Meadows is considered a developing area.

Population forecasts indicate it will gain approximately 702 residents by 2041, based on the latest AreaSearch quarterly estimate. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
