Trinity Park

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

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch, the suburb of Trinity Park's population is estimated at around 3,646 as of May 2026. This reflects an increase of 110 people (3.1%) since the 2021 Census, which reported a population of 3,536 people. The change is inferred from the resident population of 3,639, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2025 and an additional 1 validated new address since the Census date. This level of population equates to a density ratio of 1,231 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Over the past decade, Trinity Park has demonstrated resilient growth patterns with a compound annual growth rate of 1.8%, outpacing the SA4 region. Population growth for the suburb was primarily driven by interstate migration that contributed 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, 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 is applying 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 Australian non-metropolitan areas is forecast, with the suburb expected to increase by 1,058 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 28.8% in total over the 16 years.

Recent residential development output has been above average within Trinity Park when compared nationally

Trinity Park has seen around 19 dwelling approvals annually based on AreaSearch analysis. Between FY-21 and FY-25, approximately 96 homes were approved, with another 5 in FY-26 so far. Each dwelling built attracted an average of 4.7 people per year over the past five financial years.

The average construction value for new homes was $433,000. This fiscal year saw $7.3 million in commercial development approvals. Compared to Rest of Qld and nationally, Trinity Park shows around 75% of construction activity per person and ranks at the 57th percentile respectively.

Recent building activity consists solely of detached houses, maintaining the area's suburban character with space-seeking buyers attracted to detached housing. With around 275 people per approval, Trinity Park reflects a low-density area. Future projections estimate an addition of 1,051 residents by 2041. At current development rates, housing supply may struggle to keep pace with population growth, potentially intensifying buyer competition and supporting price increases.

Jobs and Skills Australia's national employment forecasts from May-25 project national employment growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Trinity Park's employment mix suggests local employment should increase by 6.7% over five years and 13.7% over ten years, assuming constant population projections.
