Holtze

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

As of Nov 2025, the estimated population of Holtze is around 2,032 people. This reflects an increase of 92 people since the 2021 Census, which reported a population of 1,940 people. The latest ABS ERP data release (June 2024) and address validation since the Census date indicate this resident population estimate for Holtze. This results in a density ratio of 49 persons per square kilometer. Overseas migration contributed approximately 59.0% to recent population gains in the suburb.

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 estimates, AreaSearch applies growth rates by age cohort from the ABS Greater Capital Region projections (released in 2023, based on 2022 data). Based on aggregated SA2-level projections, Holtze is expected to increase by 273 persons to reach a population of 2,305 by 2041. This reflects a gain of 21.4% over the 17-year period.

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

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, shows Holtze recorded around 2 residential properties granted approval annually. Over the past 5 financial years, between FY-21 and FY-25, approximately 13 homes were approved, with no approvals so far in FY-26. Despite population decline during this period, development activity has been adequate relative to population changes, which could be beneficial for buyers.

The average expected construction cost value of new dwellings is $435,000, aligning with regional trends. This financial year, $6,000 in commercial development approvals have been recorded, indicating a predominantly residential focus. Compared to Greater Darwin, Holtze shows substantially reduced construction activity, 68.0% below the regional average per person. This constrained new construction typically reinforces demand and pricing for existing properties. Nationally, this level is also below average, reflecting the area's maturity and suggesting possible planning constraints.

Recent development in Holtze has been entirely comprised of detached houses, preserving its low density nature. The emphasis on detached housing attracts space-seeking buyers. Interestingly, developers are building more traditional houses than the current mix suggests (34.0% at Census), indicating continued strong demand for family homes despite density pressures. The estimated count of 4340 people in the area per dwelling approval reflects its quiet, low activity development environment. Future projections show Holtze adding 434 residents by 2041, according to the latest AreaSearch quarterly estimate. At current development rates, new housing supply should comfortably meet demand, providing good conditions for buyers and potentially supporting growth beyond current population projections.
