Wadalba

Wadalba lies within the top 10% of areas nationally in terms of population growth performance according to AreaSearch analysis of short and medium-term trends

As of Nov 2025, the estimated population of the Wadalba statistical area (Lv2) is around 4,827. This reflects an increase since the 2021 Census, which reported a population of 4,204 people. The change is inferred from AreaSearch's estimation of the resident population at 4,719 following examination of the latest ERP data release by the ABS (June 2024) and an additional 90 validated new addresses since the Census date. This level of population equates to a density ratio of 1,263 persons per square kilometer, above the average seen across national locations assessed by AreaSearch. The Wadalba (SA2) saw a growth of 14.8% since the 2021 census, exceeding the SA4 region's growth rate of 3.7%. Interstate migration contributed approximately 72.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. Exceptional growth is predicted over the period 2022 to 2041, with the area expected to grow by 3,077 persons, reflecting a gain of 60.4% in total over the 17 years.

AreaSearch assessment of residential development activity positions Wadalba among the top 25% of areas assessed nationwide

AreaSearch analysis of ABS building approval numbers indicates Wadalba averaged approximately 35 new dwelling approvals annually over the past five financial years, totalling an estimated 177 homes. As of FY26, 22 approvals have been recorded. Historically, between FY21 and FY25, around 4.6 new residents arrived per year for each dwelling constructed. Commercial approvals totalled $21.2 million in the current financial year.

Compared to Greater Sydney, Wadalba has seen a 100% increase in construction activity per capita. New developments consist of 83% detached houses and 17% medium and high-density housing. The area has around 192 people per dwelling approval, suggesting an expanding market. Population forecasts estimate Wadalba will gain approximately 2,914 residents by 2041.

If current construction levels continue, housing supply may lag population growth, potentially intensifying buyer competition and supporting price growth.

AreaSearch analysis reveals Wadalba significantly outperforming the majority of regions assessed nationwide

Wadalba has a skilled workforce with essential services sectors well represented. Its unemployment rate was 2.9% in the past year, showing an estimated employment growth of 3.4%.

As of September 2025, 2,412 residents are employed, with an unemployment rate of 1.3% below Greater Sydney's rate of 4.2%. Workforce participation is higher at 65.3%, compared to Greater Sydney's 60.0%. Employment is concentrated in health care & social assistance, retail trade, and construction. The area specializes in health care & social assistance with an employment share of 1.4 times the regional level, but has lower representation in professional & technical services at 4.0% versus the regional average of 11.5%.

Employment opportunities locally appear limited, as indicated by the count of Census working population vs resident population. In the past year, employment increased by 3.4%, labour force grew by 4.0%, and unemployment rose by 0.6 percentage points. This contrasts with Greater Sydney where employment rose by 2.1%, labour force grew by 2.4%, and unemployment rose by 0.2 percentage points. State-level data to 25-Nov shows NSW employment contracted by 0.03% (losing 2,260 jobs), with the state unemployment rate at 3.9%. National employment forecasts from May-25 suggest national employment will expand by 6.6% over five years and 13.7% over ten years. Applying these projections to Wadalba's employment mix suggests local employment should increase by 6.6% over five years and 13.8% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not account for localised population projections.
