This shows an increase of 597 people (16.9%) since the 2021 Census, which reported a population of 3,536.

For projections, AreaSearch uses ABS/Geoscience Australia data released in 2024 with a base year of 2022 for SA2 areas. 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 from ABS Greater Capital Region projections released in 2023 based on 2022 data. By 2041, the suburb is projected to increase by 1,243 persons, reflecting a total increase of 28.4% over the 17 years.

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

AreaSearch analysis shows Trinity Park had approximately 19 dwelling approvals annually. From FY-21 to FY-25, around 96 homes were approved, with one more in FY-26. On average, 7 people moved to the area per dwelling built over these years.

This demand outpaces supply, potentially driving up prices and increasing competition among buyers. The average construction cost of new homes was $433,000. In FY-26, commercial development approvals totaled $7.3 million.

Compared to other areas, Trinity Park has around 75% of the construction activity per person nationally, placing it in the 55th percentile. All recent building activity consists of detached houses, maintaining the area's suburban character and attracting space-seeking buyers. With approximately 285 people per approval, the market is transitioning. By 2041, Trinity Park is projected to add 1,176 residents. At current development rates, housing supply may not keep pace with population growth, potentially intensifying buyer competition and supporting price increases.
