AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. 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). Considering projected demographic shifts, an above median population growth is expected for Secret Harbour. By 2041, the area's population is projected to expand by 3,032 persons, reflecting a total increase of 25.5% over the 17 years.

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

AreaSearch analysis of ABS building approval numbers shows Secret Harbour had approximately 28 new homes approved annually over the past five financial years, totalling around 140 homes. In Financial Year 26, 27 approvals have been recorded so far. On average, between Financial Years 21 and 25, 14.5 new residents arrived per year per dwelling constructed.

This indicates demand outpacing supply, which can put upward pressure on prices and increase competition among buyers. The average construction value of new homes in Secret Harbour is $392,000, aligning with regional trends. Compared to Greater Perth, Secret Harbour has significantly lower building activity, 77.0% below the regional average per person. This scarcity typically strengthens demand and prices for existing properties. However, development activity has increased recently.

Nationally, this activity is also below average, suggesting possible planning constraints in the area. New developments in Secret Harbour consist of 97.0% detached dwellings and 3.0% townhouses or apartments, maintaining the area's suburban identity with a focus on family homes. With around 221 people per dwelling approval, the market is developing. Population forecasts indicate Secret Harbour will gain approximately 3,518 residents by 2041. If current construction levels continue, housing supply may lag population growth, potentially intensifying buyer competition and supporting price growth.

In contrast, Greater Perth saw employment growth of 3.7% and labour force growth of 3.8%, with a 0.1 percentage point rise in unemployment. Jobs and Skills Australia's national employment forecasts from Sep-22 project overall employment growth of 6.6% over five years and 13.7% over ten years. 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, though this is a simple weighting extrapolation for illustrative purposes only.
