Based on analysis of ABS population updates for the broader area, as of Nov 2025, Secret Harbour's estimated population is around 13,911. This reflects an increase of 1,437 people since the 2021 Census, which reported a population of 12,474.

Secret Harbour's population growth rate of 11.5% since the 2021 census exceeded the national average of 9.7%.

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 and post-2032 growth estimation, AreaSearch utilises growth rates by age cohort provided by 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 the area, with a projected increase of 3,064 persons to reach a total of 17,975 by 2041, reflecting a 24.8% increase over the 17 years.

AreaSearch assessment of residential approval activity sees Secret Harbour among the top 30% 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 141 homes. By FY-26, 60 approvals have been recorded. This results in an average of about 14.4 new residents per year arriving for each dwelling constructed between FY-21 and FY-25, indicating demand outpaces supply which typically influences prices upwards and intensifies competition among buyers.

The average construction cost value of new homes is around $392,000, suggesting developers target the premium market segment with higher-end properties. Compared to Greater Perth, Secret Harbour has significantly lower building activity, at 77.0% below the regional average per person, which usually strengthens demand and prices for existing properties. Recent periods have seen development activity increase but it remains below national averages, reflecting the area's maturity and possible planning constraints. New developments primarily consist of detached dwellings (97.0%) with a smaller proportion of townhouses or apartments (3.0%), maintaining Secret Harbour's suburban identity with a focus on family homes. With around 312 people per dwelling approval, the developing market shows potential for growth.

According to AreaSearch's latest quarterly estimate, Secret Harbour is projected to gain approximately 3,444 residents by 2041. If current construction levels continue, housing supply may lag behind population growth, potentially exacerbating buyer competition and supporting price growth.
