AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered and years post-2032, Queensland State Government's SA2 area projections are used, released in 2023 based on 2021 data. These state projections do not provide age category splits; hence proportional growth weightings are applied in line with the ABS Greater Capital Region projections for each age cohort, released in 2023 based on 2022 data. Considering projected demographic shifts, over this period, the area's population is expected to shrink by 100 persons by 2041 according to these projections. However, growth across specific age cohorts is anticipated, led by the 85 and over age group, which is projected to increase by 525 people.
