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 ABS population updates for the broader area, and new addresses validated by AreaSearch, Trinity Beach's population is estimated at around 8,431 as of November 2025. This reflects an increase of 1,837 people (27.9%) since the 2021 Census, which reported a population of 6,594 people. The change is inferred from the resident population of 7,805 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 224 validated new addresses since the Census date. This level of population equates to a density ratio of 1,409 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Trinity Beach's growth of 27.9% since the 2021 census exceeded the SA4 region (8.3%) and the non-metro area, 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 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. However, 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. Looking at population projections moving forward, a significant population increase in the top quartile of national non-metropolitan areas is forecast, with the area expected to increase by 2,718 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of 23.3% in total over the 17 years.

AreaSearch assessment of residential development activity positions Trinity Beach among the top 25% of areas assessed nationwide

AreaSearch analysis of ABS building approval numbers shows Trinity Beach recorded around 84 residential properties granted approval each year over the past five financial years, totalling an estimated 423 homes. So far in FY-26, 10 approvals have been recorded. On average, 3.2 new residents arrive per dwelling constructed annually between FY-21 and FY-25. This has resulted in demand exceeding supply, leading to price growth and increased buyer competition.

New homes are being built at an average expected construction cost of $433,000. In FY-26, $19.8 million in commercial development approvals have been recorded, indicating balanced commercial development activity. Compared to the Rest of Qld, Trinity Beach shows 76.0% higher construction activity per person, offering buyers greater choice but with recent easing in construction activity. This is significantly above the national average, suggesting robust developer interest in the area. Recent construction comprises 97.0% standalone homes and 3.0% townhouses or apartments, preserving Trinity Beach's suburban nature and attracting space-seeking buyers.

Developers are building more traditional houses than the current mix suggests (69.0% at Census), indicating strong demand for family homes despite density pressures. With around 193 people per dwelling approval, Trinity Beach exhibits characteristics of a growth area. According to AreaSearch's latest quarterly estimate, Trinity Beach is expected to grow by 1,965 residents through to 2041. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
