AreaSearch uses 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 from 2023 based on 2021 data are adopted. However, these state projections do not provide age category splits, so AreaSearch applies proportional growth weightings in line with ABS Greater Capital Region projections released in 2023 and based on 2022 data for each age cohort. Future population trends indicate an above median growth is projected for the area, with an expected increase of 930 persons to reach a total population of 8,581 by 2041, reflecting a gain of 10.5% over the 16-year period.
