Trinity Beach

Trinity Beach lies within the top 10% of areas nationally in terms of population growth performance according to AreaSearch analysis of short and medium-term trends

Based on analysis of Australian Bureau of Statistics (ABS) population updates for the broader area, and new addresses validated by AreaSearch, the estimated population of Trinity Beach as of Nov 2025 is around 7,906. This reflects an increase of 1,312 people since the 2021 Census, which reported a population of 6,594. The change is inferred from the resident population of 7,784 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024, along with an additional 224 validated new addresses since the Census date. This level of population equates to a density ratio of 1,322 persons per square kilometer, above the average seen across national locations assessed by AreaSearch. Trinity Beach's growth of 19.9% since the 2021 census exceeded the SA4 region's 7.8%, marking it as a growth leader in the region. Population growth was primarily driven by interstate migration contributing approximately 60.0% of overall population gains during recent periods, although all drivers including overseas migration and natural growth were positive factors.

AreaSearch is adopting 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, applying proportional growth weightings in line with the ABS Greater Capital Region projections for each age cohort. Looking ahead, a significant population increase is forecast for the top quartile of national non-metropolitan areas, with Trinity Beach expected to increase by 2,669 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of 30.9% in total over the 17 years.

As of FY-26, 8 approvals have been recorded. The average new residents per year arriving per dwelling constructed between FY-21 and FY-25 was 3.2. Demand significantly exceeded new supply, typically leading to price growth and increased buyer competition.
