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 released in 2023 based on 2021 data are adopted, with proportional growth weightings applied for age cohorts as per ABS Greater Capital Region projections released in 2023. Looking ahead, significant population increases are forecasted for the top quartile of Australian non-metropolitan areas like Trinity Park, with an expected increase of 1,267 persons to 2041 based on aggregated SA2-level projections, reflecting a total increase of 39.9% over the 17-year period.
