Throsby

Throsby lies within the top quartile of areas nationally for population growth performance according to AreaSearch analysis of recent, and medium to long-term trends

Throsby's population was approximately 3,632 as of February 2026. This represented an increase of 1,227 people (51.0%) since the 2021 Census, which reported a population of 2,405 people. The change was inferred from the estimated resident population of 3,632 from the ABS as of June 2024 and an additional 32 validated new addresses since the Census date. This resulted in a population density ratio of 2,454 persons per square kilometer, placing Throsby in the upper quartile relative to national locations assessed by AreaSearch. Throsby's growth exceeded the state's (6.7%) and SA4 region's rate, marking it as a growth leader. Population growth was primarily driven by interstate migration contributing approximately 83.7% of overall population gains during recent periods, although all drivers including natural growth and overseas migration were positive factors.

AreaSearch adopted 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, age group growth rates from the ACT Government's SA2 area projections were used, also with a base year of 2022. Future population dynamics anticipated a significant increase in Throsby's top quartile of Australian statistical areas, with an expected increase of 1,165 persons to 2041 based on the latest annual ERP population numbers, reflecting a total increase of 30.5% over the 17 years.

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

Throsby has received around 78 dwelling approvals per year. Between financial years FY21 and FY25, a total of 393 homes were approved, with none yet approved in FY26. On average, 6.5 people moved to the area annually for each dwelling built over these five years.

This has led to high demand exceeding new supply, resulting in price growth and increased buyer competition. New properties are constructed at an average expected cost of $82,000, which is below regional levels, offering more affordable housing options. In FY26, commercial approvals have totaled $45.3 million, indicating strong local business investment. Compared to the Australian Capital Territory, Throsby has 602.0% more construction activity per person, reflecting robust developer confidence in the area. All new constructions since FY21 have been standalone homes, maintaining Throsby's suburban character and appealing to families seeking space.

With around 504 people moving in for each dwelling approval, Throsby exhibits a developed market. By 2041, Throsby is projected to gain 1,108 residents. At current development rates, new housing supply should comfortably meet demand, providing favorable conditions for buyers and potentially supporting population growth beyond current projections.

Employment performance in Throsby ranks among the strongest 15% of areas evaluated nationally

Throsby has a highly educated workforce with professional services showing strong representation. Its unemployment rate was 2.2% in the past year, with an estimated employment growth of 3.0%. As of September 2025, 2,043 residents are employed while the unemployment rate is 1.4% lower than the Australian Capital Territory's rate of 3.6%.

Workforce participation is at 82.9%, compared to the Australian Capital Territory's 72.5%. According to Census responses, only 11.9% of residents work from home. Employment is concentrated in public administration & safety, professional & technical, and health care & social assistance sectors. The area specializes particularly in professional & technical employment, with a share 1.3 times the regional level.

However, public administration & safety has limited presence at 28.9% compared to the regional average of 30.4%. The predominantly residential area appears to offer limited local employment opportunities based on Census data. During the year to September 2025, employment levels increased by 3.0%, and labour force grew by 2.5%, leading to a fall in unemployment rate by 0.5 percentage points. In comparison, Australian Capital Territory recorded employment growth of 1.4% with unemployment falling by 0.2 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 suggest that while national employment is projected to expand by 6.6% over five years and 13.7% over ten years, growth rates differ significantly between industry sectors. Applying these projections to Throsby's employment mix indicates local employment should increase by 6.8% over five years and 13.7% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not consider localized population projections.
