Trevallyn

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

Trevallyn's population, as per AreaSearch's analysis, is 4878 as of May 2026. This figure shows an increase of 52 people from the 2021 Census total of 4826. The change is inferred from ABS' estimated resident population of 4874 in June 2025 and additional validated new addresses since the Census date. This results in a density ratio of 501 persons per square kilometer. Trevallyn's growth rate of 1.1% since the Census places it within 1.5 percentage points of its SA3 area (2.6%). Overseas migration contributed approximately 51.7% to recent population gains.

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 post-2032 growth by age group, Tasmania State Government's Regional/LGA projections from 2022 with a base year of 2021 are adopted, adjusted using weighted aggregation methods. Future projections indicate lower quartile growth for Australian non-metropolitan areas, with Trevallyn expected to increase by 14 persons to 2041, reflecting an overall increase of 0.2% over the 16-year period.

AreaSearch assessment of residential development drivers sees a low level of activity in Trevallyn, placing the area among the bottom 25% of areas assessed nationally

Trevallyn has received approximately six dwelling approvals annually over the past five financial years, totaling 31 homes. As of FY26, five approvals have been recorded. On average, each dwelling has accommodated 2.3 new residents per year between FY21 and FY25, indicating strong demand which may support property values. The average construction cost value of new homes is $319,000.

In FY26, $153,000 in commercial approvals have been registered, reflecting the area's residential focus. Compared to the Rest of Tas., Trevallyn has significantly lower building activity, 71.0% below the regional average per person. This limited new construction typically reinforces demand and pricing for existing dwellings. The area's development is also below national averages, suggesting maturity and potential planning constraints. All recent developments have been detached houses, maintaining Trevallyn's low-density character and attracting space-seeking buyers.

As of now, there are an estimated 1576 people per dwelling approval in the area. Future projections estimate a population increase of ten residents by 2041 (AreaSearch quarterly estimate). Given current development patterns, new housing supply should meet demand, providing favorable conditions for buyers and potentially facilitating further population growth beyond current projections.
