Trott Park

Trott Park is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

As of May 2026, the estimated population of the suburb of Trott Park is around 3,185, reflecting a 2.0% increase from the 2021 Census figure of 3,124 people. This increase is inferred from AreaSearch's analysis of the latest ERP data release by the ABS in June 2025 and validation of one new address since the Census date. The population density stands at approximately 1,061 persons per square kilometer, aligning with averages seen across locations assessed by AreaSearch. Overseas migration contributed significantly to this growth, accounting for about 66.0% of overall population gains during recent periods. AreaSearch employs 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, the SA State Government's Regional/LGA projections are adopted, based on 2021 data and released in 2023, with adjustments made using a method of weighted aggregation. Looking ahead, population growth is projected to be at a lower quartile for national areas. By 2041, the suburb of Trott Park is expected to expand by 129 persons, reflecting an increase of 4.0% in total over the 16-year period, based on aggregated SA2-level projections.

The level of residential development activity in Trott Park is very low in comparison to the average area assessed nationally by AreaSearch

AreaSearch analysis shows Trott Park had approximately 3 new homes approved annually over the past 5 financial years, totalling around 19 dwellings. Up to FY26, 3 approvals have been recorded. On average, about 0.3 people moved to the area per year for each dwelling built between FY21 and FY25. This suggests new construction is meeting or exceeding demand, providing more options for buyers and potentially boosting population growth.

The average expected construction cost of new dwellings was $536,000, indicating a focus on premium developments. In FY26, there were $35,000 in commercial approvals, predominantly residential. Compared to Greater Adelaide, Trott Park had significantly reduced construction activity (83.0% below average per person), which may strengthen demand and prices for existing properties. This activity was also below national averages, reflecting the area's maturity and possible planning constraints. Recent building activity comprised entirely detached houses, preserving Trott Park's suburban nature with an emphasis on space-seeking buyers.

The location had approximately 2116 people per dwelling approval, indicating an established market. By 2041, Trott Park is projected to grow by 129 residents (AreaSearch quarterly estimate). If current development rates continue, housing supply may not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth.
