AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area as released in 2024 with a base year of 2022. For areas not covered by this data and years post-2032, the SA State Government's Regional/LGA projections by age category are adopted, based on 2021 data and adjusted using a method of weighted aggregation of population growth from LGA to SA2 levels. According to these projections, the suburb is expected to experience significant population growth in the top quartile of statistical areas across the nation, with an increase of 1,133 persons forecast by 2041. This would reflect a total gain of 28.9% over the 17-year period.
