Hilbert

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

As of Feb 2026, the estimated population of the suburb of Hilbert is around 6,121, reflecting an increase of 1,956 people since the 2021 Census. This growth represents a 47.0% increase from the previous population of 4,165. The change is inferred from AreaSearch's resident population estimate of 5,893 following examination of the latest ERP data release by the ABS in June 2024 and an additional 1,058 validated new addresses since the Census date. This results in a density ratio of 666 persons per square kilometer. The suburb's growth rate exceeded the national average of 9.9% since the 2021 census. Interstate migration contributed approximately 56.00000000000001% to overall population gains in recent periods, although all drivers including natural growth and overseas migration were positive factors.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch utilises the growth rates by age cohort provided by the ABS in its latest Greater Capital Region projections released in 2023 based on 2022 data. Future population dynamics project an above median growth for statistical areas across the nation, with Hilbert expected to expand by 1,197 persons to reach a total of 7,318 by 2041, reflecting an increase of 1.1% in total over the 17 years.

AreaSearch assessment of residential development activity positions Hilbert among the top 25% of areas assessed nationwide

Based on AreaSearch analysis of ABS building approval numbers, Hilbert has recorded around 221 residential properties granted approval per year. Over the past five financial years, from FY-21 to FY-25, approximately 1,108 homes have been approved, with an additional 109 approved so far in FY-26. On average, about 0.9 new residents arrive per year for each new home built over these five years.

This suggests that new construction is keeping pace with or exceeding demand, offering buyers more options and potentially supporting population growth beyond current expectations. The average expected construction cost value of new dwellings in Hilbert is $361,000, slightly above the regional average. In FY-26 alone, $74.4 million worth of commercial approvals have been registered, indicating strong commercial development momentum. Compared to Greater Perth, Hilbert records 356.0% more new home approvals per person, providing buyers with ample choice and suggesting strong developer confidence in the location. The majority of new building activity consists of detached dwellings, at 97.0%, while attached dwellings account for 3.0%.

This preserves the area's low-density nature and attracts space-seeking buyers. Currently, Hilbert reflects a developing area with around 21 people per approval. Looking ahead, Hilbert is expected to grow by 66 residents through to 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.
