Holden Hill

Holden Hill 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 November 2025, Holden Hill's population is estimated at around 120,710, reflecting an increase of 6,526 people since the 2021 Census. This growth represents a 5.7% increase from the previous population count of 114,184. The change is inferred from AreaSearch's estimation of the resident population at 3,842 based on the latest ERP data release by the ABS in June 2024, along with an additional 27 validated new addresses since the Census date. This results in a population density ratio of 63,867 persons per square kilometer. Holden Hill's growth rate exceeded that of its SA3 area (4.5%), positioning it as a growth leader in the region. Overseas migration was the primary driver of population gains during recent periods, with natural growth and interstate migration playing minimal roles.

AreaSearch adopts 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 used, adjusted employing a method of weighted aggregation of population growth from LGA to SA2 levels. Looking ahead, demographic trends suggest a population increase just below the median of national regional areas. The suburb is expected to grow by 3,891 persons to 2041 based on aggregated SA2-level projections, reflecting an overall increase of 4.2% over the 17-year period.

Residential development activity is lower than average in Holden Hill according to AreaSearch's national comparison of local real estate markets

AreaSearch analysis of ABS building approval numbers indicates Holden Hill has received around 219 dwelling approvals annually over the past five financial years, totalling an estimated 1096 homes. As of FY-26, 63 approvals have been recorded. On average, 2 people per year move to the area per new home constructed between FY-21 and FY-25, indicating healthy demand for property values. New homes are being built at an average expected construction cost value of $738000, suggesting developers focus on the premium market with high-end developments.

In FY-26, Holden Hill has recorded $404.5 million in commercial development approvals, showing strong commercial development momentum compared to Rest of SA. Holden Hill shows approximately 75% of construction activity per person and ranks among the 46th percentile nationally, suggesting limited buyer options while strengthening demand for established dwellings. This level is below the national average, indicating the area's established nature and potential planning limitations. New building activity comprises 97.0% detached dwellings and 3.0% attached dwellings, maintaining Holden Hill's traditional low density character focused on family homes appealing to those seeking space. This represents a notable shift from the area's existing housing composition (currently 152.0% houses), indicating decreasing availability of developable sites and reflecting changing lifestyles and demand for diverse, affordable housing options.

The estimated population per dwelling approval is 682 people, reflecting Holden Hill's quiet development environment with stable or declining population expected in the future, potentially creating opportunities for buyers.
