Thornlands

Thornlands lies within the top quartile of areas nationally for population growth performance according to AreaSearch analysis of recent, and medium to long-term trends

Thornlands' population was around 21,800 as of November 2025. This figure reflects an increase of 2,537 people since the 2021 Census, which reported a population of 19,263. The growth is inferred from ABS's estimated resident population of 21,476 in June 2024 and an additional 402 validated new addresses since the Census date. This results in a population density ratio of 1,006 persons per square kilometer. Thornlands' growth rate of 13.2% since the 2021 census exceeded both the SA4 region's 8.2% and the national average. Interstate migration contributed approximately 52.7% of overall population gains during recent periods, with all drivers including overseas migration and natural growth being positive factors.

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. These state projections do not provide age category splits; thus, 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 project an above median growth for Australian statistical areas, with Thornlands expected to grow by 3,792 persons to reach a total of 25,592 by 2041, reflecting a gain of 15.9% over the 17-year period.
