Watsonia

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

Watsonia's population, as of May 2026, is approximately 9,511. This reflects a growth of 3.0% since the 2021 Census, which reported a population of 9,236. The increase is inferred from ABS data showing an estimated resident population of 9,504 in June 2025 and an additional 50 validated new addresses since the Census date. This results in a population density of 2,509 persons per square kilometer, placing Watsonia in the upper quartile nationally according to AreaSearch's assessments. Watsonia's growth rate is within 2.5 percentage points of its SA3 area (5.5%), indicating strong growth fundamentals. Overseas migration contributed approximately 57.3% of overall population gains during recent periods.

AreaSearch uses ABS/Geoscience Australia projections released in 2024 with a base year of 2022 for each SA2 area. For areas not covered by this data, AreaSearch employs the VIC State Government's Regional/LGA projections from 2023, adjusting using a method of weighted aggregation of population growth from LGA to SA2 levels. Growth rates by age group are applied across all areas for years 2032 to 2041. By 2041, Watsonia is forecasted to experience significant population growth, with an expected increase of 2,949 persons based on the latest annual ERP population numbers. This reflects a total gain of 30.9% over the 16-year period.

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

Watsonia has recorded approximately 27 residential properties granted approval annually. Over the past five financial years, from FY-21 to FY-25, around 135 homes were approved, with an additional 12 approved so far in FY-26. On average, about 0.1 person per year has moved to the area for each dwelling built during these years.

This suggests that new construction is meeting or exceeding demand, providing buyers with more options and enabling population growth that may surpass current expectations. The average expected construction cost of new properties is approximately $381,000. In FY-26, there have been $23.6 million in commercial approvals, indicating steady commercial investment activity in the area. Compared to Greater Melbourne, Watsonia has significantly less development activity, with 57.0% below the regional average per person. This scarcity of new homes typically strengthens demand and prices for existing properties. New development in Watsonia consists of an equal split between detached dwellings (50.0%) and medium to high-density housing (50.0%). This focus on higher-density living creates more affordable entry points, suiting downsizers, investors, and first-home buyers.

This represents a significant change from the current housing mix, which is predominantly houses (91.0%), reflecting reduced availability of development sites and addressing shifting lifestyle demands and affordability requirements. Watsonia has approximately 488 people per dwelling approval, indicating an established area. According to AreaSearch's latest quarterly estimate, Watsonia is forecasted to gain around 2,942 residents by 2041. If current construction levels persist, housing supply may lag population growth, potentially intensifying buyer competition and underpinning price growth in the future.
