Secret Harbour

Population growth drivers in Secret Harbour are above average based on AreaSearch's ranking of recent, and medium to long-term trends

As of Feb 2026, the estimated population of the suburb of Secret Harbour is around 14,096. This reflects an increase of 1,622 people since the 2021 Census, which reported a population of 12,474. The change was inferred from AreaSearch's estimation of the resident population at 13,843 following examination of the latest ERP data release by the ABS in June 2024 and an additional 17 validated new addresses since the Census date. This level of population equates to a density ratio of 2,155 persons per square kilometer, above the average seen across national locations assessed by AreaSearch. Secret Harbour's growth rate of 13.0% since the 2021 census exceeded the national average of 9.9%, marking it as a growth leader in the region. Population growth was primarily driven by interstate migration contributing approximately 37.0% of overall population gains during recent periods, although all drivers including overseas migration and natural growth 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 growth rates by age cohort provided by the ABS in its latest Greater Capital Region projections released in 2023, based on 2022 data. Moving forward with demographic trends, an above median population growth is projected for the area, with an expected increase of 3,040 persons to 2041, reflecting a total increase of 22.9% over the 17 years.

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

Secret Harbour experienced around 28 dwelling approvals per year based on AreaSearch analysis of ABS building approval numbers. Approximately 141 homes were approved between FY-21 and FY-25, with an additional 60 approved in FY-26.

This results in an average of 14.4 new residents per year for every home built over the past five financial years. The demand for housing significantly outpaces supply, which typically puts upward pressure on prices and increases competition among buyers. Developers focus on the premium market with high-end developments, as evidenced by an average construction value of $392,000 per dwelling. Compared to Greater Perth, Secret Harbour records markedly lower building activity, at 77.0% below the regional average per person. This scarcity of new homes typically strengthens demand and prices for existing properties.

Construction activity has intensified recently but remains lower than nationally, reflecting market maturity and possible development constraints. New developments consist of 97.0% detached dwellings and 3.0% townhouses or apartments, sustaining the area's suburban identity with a concentration of family homes suited to buyers seeking space. With around 312 people per dwelling approval, Secret Harbour shows a developing market. Future projections estimate that Secret Harbour will add approximately 3,228 residents by 2041 based on the latest AreaSearch quarterly estimate. At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.

As of September 2025, 8,787 residents are employed, with an unemployment rate of 0.7% below Greater Perth's rate of 4.0%. Workforce participation is high at 84.9%, compared to Greater Perth's 71.6%.

However, professional & technical employment is limited at 4.4%, compared to the regional average of 8.2%. The predominantly residential area offers limited local employment opportunities, as indicated by the count of working population versus resident population. Between September 2024 and September 2025, employment levels increased by 4.2% and labour force increased by 4.6%, causing a rise in unemployment rate of 0.4 percentage points. In comparison, Greater Perth recorded employment growth of 2.9% and labour force growth of 3.0%, with marginal unemployment increase. Jobs and Skills Australia's national employment forecasts from May-25 offer insights into potential future demand within Secret Harbour. These projections estimate national employment growth at 6.6% over five years and 13.7% over ten years, but growth rates vary significantly between industry sectors. Applying these projections to Secret Harbour's employment mix suggests local employment should increase by 5.8% over five years and 12.6% over ten years, based on a simple weighting extrapolation for illustrative purposes only.
