Tarragindi

An assessment of population growth drivers in Tarragindi reveals an overall ranking slightly below national averages considering recent, and medium term trends

Tarragindi's population was around 11,616 as of November 2025. This showed an increase of 672 people from the 2021 Census figure of 10,944. The growth was inferred from ABS's estimated resident population of 11,593 in June 2024 and additional validated new addresses since the Census date. This resulted in a population density of 2,553 persons per square kilometer, placing Tarragindi in the upper quartile nationally according to AreaSearch assessments. The area's 6.1% growth since the census was within 2.8 percentage points of the national average (8.9%). Overseas migration contributed approximately 60.6% of overall population gains recently.

AreaSearch uses 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 are adopted, released in 2023 based on 2021 data. Note that these state projections do not provide age category splits; thus, AreaSearch applies proportional growth weightings aligned with ABS Greater Capital Region projections for each age cohort. Considering projected demographic shifts, lower quartile growth of Australian statistical areas is anticipated. Tarragindi is expected to grow by 350 persons to reach a total population of 12,964 by 2041, reflecting an increase of 2.8% over the 17-year period based on the latest annual ERP population numbers.

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

Tarragindi averaged around 63 new dwelling approvals annually over the past five financial years, totalling 317 homes. As of FY26, 21 approvals have been recorded. Between FY21 and FY25, an average of 1.6 people moved to the area per dwelling built. However, this increased to 4.7 people per dwelling over the past two financial years, suggesting growing popularity and potential undersupply. New homes are being built at an average expected construction cost value of $721,000, indicating a focus on the premium market.

In FY26, $3.0 million in commercial approvals have been registered, showing limited commercial development focus compared to residential. Compared to Greater Brisbane, Tarragindi has moderately higher development activity, at 31.0% above the regional average per person over the five-year period. New building activity comprises 67.0% standalone homes and 33.0% townhouses or apartments, expanding medium-density options and creating a mix of opportunities across price brackets. This shows a significant change from the current housing mix, which is currently 95.0% houses.

The location has approximately 237 people per dwelling approval, indicating a low density market. Population forecasts estimate Tarragindi will gain 327 residents by 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.
