Secret Harbour

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

According to evaluations of ABS demographic updates covering the wider region, alongside recent addresses verified by AreaSearch subsequent to the Census, the population of the suburb of Secret Harbour is projected to be approximately 13,737 in May 2026. This represents an addition of 1,263 people (10.1%) compared to the 2021 Census, which documented a population of 12,474 residents. The modification is calculated using a resident population of 13,693, estimated by AreaSearch using the newest ABS ERP figures from June 2025 combined with 46 verified new addresses registered after the Census date. This population size results in a density of 2,100 persons per square kilometer, exceeding the typical ratio observed across Australian areas analyzed by AreaSearch. The 10.1% expansion of the suburb of Secret Harbour since the 2021 census outpaced the national benchmark of 9.3%, placing it among the key growth areas in the territory. This population rise was mostly driven by arrivals from other states, which accounted for roughly 37.0% of the total demographic growth in recent times, though all indicators including international arrivals and natural increase contributed positively.

AreaSearch incorporates projections from the ABS and Geoscience Australia for every SA2 zone, published in 2024 using 2022 as the baseline year. For SA2 zones missing this information, and to calculate growth beyond 2032, AreaSearch applies the age-specific growth metrics published by the ABS in its latest Greater Capital Region forecasts from 2023, based on 2022 data. Evaluating these demographic developments, the suburb of Secret Harbour is anticipated to experience population growth above the national median, with local numbers expanding by 2,655 individuals by 2041 according to collective SA2 projections, representing a total rise of 19.0% over the 16 years.

Residential development activity is slightly higher than average within Secret Harbour when compared nationally

Based on AreaSearch assessments of ABS residential construction approvals distributed from statistical zones, Secret Harbour has recorded an average of approximately 16 new residential approvals annually, yielding an estimated 84 residences during the previous 5 financial years. Thus far in FY-26, there have been 63 approvals registered. With an average of 10.5 new residents arriving for every constructed home over the past 5 financial years (from FY-21 to FY-25), demand is outstripping supply, which commonly pushes property values upward and increases buyer rivalry, while new residences are being built with an average value of $392,000, showing that builders are focusing on the higher-end sector with upscale properties.

In comparison to Greater Perth, Secret Harbour shows significantly reduced residential construction, registering 86.0% below the regional per capita norm. This undersupply of fresh inventory generally bolsters demand and valuations for pre-existing properties, although construction volume has accelerated recently. This level of activity also falls below the national norm, reflecting a established market and indicating potential regulatory limits. Furthermore, all recent building activity has been concentrated in single family homes, preserving the established low-density feel of the area with properties suited for families wanting space. With approximately 468 people for every home approval, Secret Harbour displays a mature housing sector.

Demographic projections indicate Secret Harbour is set to add 2,611 residents by 2041, based on the latest quarterly calculations from AreaSearch. If current building rates do not change, the supply of homes may fall behind population growth, which is likely to heighten competition among buyers and support upward price movements.

Secret Harbour has moderate levels of nearby infrastructure activity, ranking in the 43rdth percentile nationally

Employment performance in Secret Harbour exceeds national averages across key labour market indicators

Secret Harbour possesses a skilled labor pool, with strong representation in basic services fields, and an unemployment rate of just 3.3%, according to AreaSearch collated statistical area data. As of March 2026, there are 7,869 residents employed, which is 0.9% lower than the unemployment rate of 4.2% in Greater Perth, while participation in the labor market is exceptionally high at 76.7% compared to 70.2% across Greater Perth. Census records show that a modest 6.9% of employees worked from home, though the influence of pandemic restrictions during this period should be kept in mind.

The primary employment fields for residents are health care & social assistance, construction, and mining. The community displays a marked concentration in the mining industry, with employment levels 1.4 times higher than the regional average. Conversely, professional & technical roles are underrepresented, making up only 4.4% of the local workforce compared to 8.2% in Greater Perth. This mostly residential locality appears to provide few local employment options, as shown by comparing the count of census workers against the resident population.

According to AreaSearch evaluations of SALM and ABS statistics aggregated from regional data, the local labor force contracted by 2.9% alongside a 3.1% reduction in employment during the year ending March 2026, leading to a 0.2 percentage point rise in unemployment. This stands in contrast to Greater Perth, which saw employment grow by 2.0%, the labor force expand by 2.5%, and unemployment tick up by 0.4 percentage points. National forecasts from Jobs and Skills Australia released in May-25 offer additional context on future demand patterns in Secret Harbour. These projections, spanning five and ten-year horizons, have been applied to the local workforce structure to predict employment trends. While overall national employment is projected to grow by 6.6% over five years and 13.7% over ten years, the rates of change vary widely across different sectors. Applying these industry projections to the local employment distribution suggests that local job numbers will grow by 5.8% over five years and 12.6% over ten years, though this is a basic weighted projection for visualization and does not integrate local population growth estimates.
