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 Feb 2026, the estimated population of the suburb of Wadalba is around 4,835. This figure reflects an increase of 631 people since the 2021 Census, which reported a population of 4,204. The change was inferred from AreaSearch's estimate of the resident population at 4,719 in June 2024, following examination of the latest ERP data release by the ABS and validation of an additional 94 new addresses since the Census date. This results in a population density ratio of 1,265 persons per square kilometer, which is higher than the average seen across national locations assessed by AreaSearch. Wadalba's growth rate of 15.0% since the 2021 census exceeded that of both its SA4 region (3.7%) and SA3 area. The primary driver for this population growth was interstate migration, contributing approximately 72.0% of overall population gains during recent periods.

However, all drivers including natural growth and overseas migration were positive factors. AreaSearch is using ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, NSW State Government's SA2 level projections released in 2022 with a base year of 2021 are utilized. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. By 2041, the suburb of Wadalba is predicted to experience exceptional growth, placing it in the top 10 percent of statistical areas analysed by AreaSearch. According to aggregated SA2-level projections, the area is expected to grow by 3,768 persons over this period, reflecting a gain of 75.5% in total population over the 17 years.
