Watsonia's population is 9,559 as of February 2026, reflecting a 3.5% increase since the 2021 Census which reported 9,236 people.

AreaSearch uses ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022, and VIC State Government's Regional/LGA projections from 2023 adjusted to SA2 levels for areas not covered by the ABS data.

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 9 approved so far in FY-26. On average, only 0.1 person per year moved to the area for each dwelling built over these five years.

This pace of new construction is matching or outpacing demand, providing buyers with more options and enabling population growth that could exceed current expectations. The average expected construction cost value of new properties in Watsonia is $381,000. In FY-26, there have been $23.6 million worth of commercial approvals, indicating steady commercial investment activity. Compared to Greater Melbourne, Watsonia has significantly less development activity, approximately 57.0% below the regional average per person. This scarcity typically strengthens demand and prices for existing properties. Nationally, development levels are also lower than in Watsonia, reflecting market maturity and possible development constraints. 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 and suits downsizers, investors, and first-home buyers, marking a significant change from the current housing mix which is predominantly houses (91.0%). As of now, Watsonia has approximately 488 people per dwelling approval, reflecting an established area. According to AreaSearch's latest quarterly estimate, Watsonia is forecasted to gain 2,889 residents by 2041. If current construction levels persist, housing supply could lag population growth, potentially intensifying buyer competition and underpinning price growth.
