AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, and for years post-2032, Queensland State Government's SA2 area projections are adopted, released in 2023 and based on 2021 data. It should be noted that these state projections do not provide age category splits; hence where utilised, AreaSearch is applying proportional growth weightings in line with the ABS Greater Capital Region projections for each age cohort (released in 2023, based on 2022 data). As we examine future population trends, projections indicate a decline in overall population by 239 persons by 2041. However, growth across specific age cohorts is anticipated, led by the 85 and over age group, projected to grow by 397 people.
