Based on AreaSearch's analysis, Trinity Beach - Smithfield's population is around 20,795 as of Feb 2026. This reflects an increase of 4,004 people (23.8%) since the 2021 Census, which reported a population of 16,791 people.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, and for years post-2032, Queensland State Government's SA2 area projections, released in 2023 and based on 2021 data, are adopted. It should be noted that these state projections do not provide age category splits; hence, where utilised, AreaSearch applies proportional growth weightings in line with the ABS Greater Capital Region projections (released in 2023, based on 2022 data) for each age cohort. Considering the projected demographic shifts, a significant population increase in the top quartile of non-metropolitan areas nationally is forecast, with the area expected to increase by 6,439 persons by 2041 based on the latest annual ERP population numbers, reflecting an increase of 24.4% in total over the 17 years.
