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 since the Census Trinity Park's population is estimated at around 4128 as of Nov 2025. This reflects an increase of 592 people (16.7%) since the 2021 Census, which reported a population of 3536 people. The change is inferred from the resident population of 3900, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 3 validated new addresses since the Census date. This level of population equates to a density ratio of 1394 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Trinity Park's 16.7% growth since the 2021 census exceeded the SA4 region (8.3%), along with the non-metro area, marking it as a growth leader in the region. Population growth for the area 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. Considering the projected demographic shifts, a significant population increase in the top quartile of national regional areas is forecast, with the Trinity Park statistical area (Lv2) expected to expand by 1251 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 28.5% in total over the 17 years.

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

Based on AreaSearch analysis of ABS building approval numbers in Trinity Park, there have been approximately 19 new dwelling approvals each year on average. Between financial years FY21 to FY25, around 96 homes were approved, with one more approved so far in FY26. On average, about 7 people moved to the area for each dwelling built over these five years.

This significant demand outpaces supply, which typically leads to upward pressure on prices and increased competition among buyers. New properties are constructed at an average expected cost of $433,000. In FY26, there have been $7.3 million in commercial development approvals recorded, indicating limited commercial development focus compared to residential growth.

When comparing Trinity Park's construction activity per person with the rest of Queensland, it shows approximately 75%. Nationally, it ranks around the 55th percentile among assessed areas. Recent building activity consists solely of detached houses, preserving the area's suburban nature and attracting space-seeking buyers. Currently, there are about 285 people per dwelling approval in Trinity Park, suggesting a transitioning market. According to AreaSearch's latest quarterly estimate, Trinity Park is projected to add around 1,176 residents by 2041. If current development rates continue, housing supply may struggle to keep pace with population growth, potentially intensifying buyer competition and supporting price increases in the area.

The exceptional employment performance in Trinity Park places it among Australia's strongest labour markets

Trinity Park has a skilled workforce with essential services sectors well represented. The unemployment rate was 1.1% as of AreaSearch's aggregation of statistical area data.

As of September 2025, 2,325 residents were in work while the unemployment rate was 3.0% below Rest of Qld's rate of 4.1%. Workforce participation stood at 69.0%, significantly higher than Rest of Qld's 59.1%. Employment among residents is concentrated in health care & social assistance, retail trade, and construction.

Agriculture, forestry & fishing has limited presence with 1.0% employment compared to the regional average of 4.5%. The predominantly residential area appears to offer limited local employment opportunities, as indicated by the count of Census working population vs resident population. Between July 2024 and June 2025, labour force decreased by 1.4% while employment declined by 1.6%, causing unemployment rate to rise by 0.2 percentage points. This compares to Rest of Qld where employment grew by 1.7%, labour force expanded by 2.1%, and unemployment rose by 0.3 percentage points. To provide broader context, state-level data up to 25-Nov-25 shows QLD employment contracted by 0.01% (losing 1,210 jobs), with the state unemployment rate at 4.2%, closely aligned with the national rate of 4.3%. Jobs and Skills Australia's national employment forecasts from May-25 project national employment to expand by 6.6% over five years and 13.7% over ten years, but growth rates vary significantly between industry sectors. 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.
