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