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 November 2025, the estimated population of Wadalba is around 4,654. This reflects an increase of 450 people since the 2021 Census, which reported a population of 4,204. The change is inferred from AreaSearch's estimation of the resident population at 4,547 following examination of the latest ERP data release by the ABS in June 2024 and an additional 90 validated new addresses since the Census date. This level of population equates to a density ratio of 1,218 persons per square kilometer. Wadalba's growth rate of 10.7% since the 2021 census exceeded both the SA4 region (3.1%) and the SA3 area, marking it as a growth leader in the region. 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, and NSW State Government's SA2 level projections for areas not covered by this data, released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Exceptional growth is predicted over this period, placing Wadalba in the top 10 percent of national statistical areas, with an expected increase of 3,071 persons to 2041 based on aggregated SA2-level projections, reflecting a total increase of 66.2% 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 shows Wadalba had around 35 dwelling approvals per year over the past 5 financial years (FY-21 to FY-25), totalling approximately 177 homes. As of FY-26, 14 approvals have been recorded. On average, 4.6 people moved to the area annually for each dwelling built between FY-21 and FY-25. This indicates supply is lagging demand, likely leading to heightened buyer competition and pricing pressures.

The average construction cost of new properties was $380,000, below regional norms, reflecting more affordable housing options. In FY-26, $35.7 million in commercial development approvals have been recorded, demonstrating high levels of local commercial activity. Compared to Greater Sydney, Wadalba has 100.0% more construction activity per person. New building activity consists of 81.0% standalone homes and 19.0% townhouses or apartments, maintaining the area's suburban character focused on family homes.

With around 119 people per dwelling approval, Wadalba exhibits growth area characteristics. By 2041, AreaSearch estimates Wadalba will grow by 3,081 residents. At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.
