An assessment of population growth drivers in Seddon reveals an overall ranking slightly below national averages considering recent, and medium term trends

As of November 2025, the population of Seddon is estimated at around 5,462 people. This reflects an increase of 319 individuals since the 2021 Census, which reported a population of 5,143 people in the suburb of Seddon (Vic.).

AreaSearch employs ABS/Geoscience Australia projections for each SA2 area as released in 2024 using a base year of 2022, and VIC State Government's Regional/LGA projections adjusted by weighted aggregation for areas not covered by this data. By 2041, the suburb is projected to increase its population by 18.6%, adding approximately 1,012 persons based on aggregated SA2-level projections.

Recent residential development output has been above average within Seddon when compared nationally

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data in Seddon, indicates approximately 66 dwellings receiving development approval annually over the past five financial years ending June 2021. This totals an estimated 334 homes. As of June 2022 (FY-26), six approvals have been recorded. Despite population decline in recent years, development activity has been relatively adequate, benefiting buyers while new homes are constructed at an average expected cost value of $588,000, higher than regional norms due to quality-focused development.

This financial year has seen $35.7 million in commercial development approvals, demonstrating high levels of local commercial activity. Compared to Greater Melbourne, Seddon maintains similar construction rates per person, preserving market equilibrium consistent with surrounding areas, and significantly above the national average, indicating robust developer interest. New building activity shows 7.0% standalone homes and 93.0% medium and high-density housing, reflecting reduced availability of development sites and shifting lifestyle demands and affordability requirements. This is a considerable change from the current housing mix of 67.0% houses. With around 43 people per dwelling approval, Seddon shows characteristics of a low density area. Future projections estimate an addition of 1,018 residents by 2041 (from AreaSearch's latest quarterly estimate).

Current construction levels should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.
