Throsby

Throsby lies within the top 10% of areas nationally in terms of population growth performance according to AreaSearch analysis of short and medium-term trends

Based on analysis of ABS population updates for the broader area, as of Nov 2025, the estimated population of Throsby is around 3,575. This reflects an increase of 1,170 people since the 2021 Census, which reported a population of 2,405 in the suburb. The change was inferred from AreaSearch's estimation of the resident population following examination of the latest ERP data release by the ABS (June 2024) and an additional 32 validated new addresses since the Census date. This level of population equates to a density ratio of 2,415 persons per square kilometer, placing Throsby in the upper quartile relative to national locations assessed by AreaSearch. The suburb's growth of 48.6% since the 2021 census exceeded the state's growth rate of 5.9%, marking it as a growth leader in the region. Population growth was primarily driven by interstate migration, contributing approximately 84.0% of overall population gains during recent periods.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered by this data and years post-2032, age group growth rates from the ACT Government's SA2 area projections, with 2022 as a base, are adopted. Considering projected demographic shifts, a significant population increase in the top quartile of national areas is forecast for Throsby, with an expected growth of 1,165 persons to 2041 based on aggregated SA2-level projections, reflecting a gain of 32.6% in total over the 17 years.

AreaSearch assessment of residential approval activity sees Throsby among the top 30% of areas assessed nationwide

AreaSearch analysis of ABS building approval numbers allocated from statistical area data shows Throsby experienced approximately 77 dwelling approvals per year over the past five financial years, totalling around 388 homes. As of FY26, no approvals have been recorded yet. Historically, an average of 6.6 new residents arrived per dwelling constructed annually between FY21 and FY25. This indicates supply is lagging demand, potentially leading to heightened buyer competition and pricing pressures.

The average construction value for new homes in Throsby is $438,000, which is higher than regional norms due to quality-focused development. In the current financial year, commercial approvals totalling $45.3 million have been registered, indicating high levels of local commercial activity. Compared to the Australian Capital Territory, Throsby has 596.0% more construction activity per person, offering buyers greater choice. However, building activity has slowed in recent years. This level is significantly above the national average, suggesting robust developer interest in the area.

Recent development has consisted entirely of standalone homes, maintaining Throsby's traditional suburban character with a focus on family homes appealing to those seeking space. With around 491 people per dwelling approval, Throsby exhibits characteristics of a developed market. Population forecasts indicate Throsby will gain approximately 1,165 residents by 2041, based on the latest AreaSearch quarterly estimate. Given current development rates, new housing supply should comfortably meet demand, providing favourable conditions for buyers and potentially supporting growth beyond current population projections.

Limited local employment opportunities are indicated by Census working population vs resident population count.

In contrast, ACT had employment growth of 1.9% and a 0.3 percentage point drop in unemployment. Jobs and Skills Australia's national employment forecasts from Sep-22 project national employment to expand by 6.6% over five years and 13.7% over ten years. Applying these projections to Throsby's employment mix suggests local employment should increase by 6.8% over five years and 13.7% over ten years, based on simple weighting extrapolation for illustrative purposes only.
