AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered by this data and years post-2032, the SA State Government's Regional/LGA projections by age category are adopted, released in 2023 and based on 2021 data, with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Future population trends suggest an increase just below the median of statistical areas across the nation, with the suburb expected to increase by 209 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 3.5% in total over the 17 years.
