Mosman Park
University qualifications at 59.0% run 28.9 percentage points above the national average, and SEIFA IEO decile 10 confirms Mosman Park as one of Perth's most educationally elite suburbs. Mining employs 8.0% of workers (273 people), an unusually high share for a suburb 11 km from Perth CBD, reflecting the FIFO executive class who lives in premium riverside locations. The volunteering rate of 26.5% is the highest in this cohort, nearly double the national median, consistent with an established-wealth community with time and social capital to donate. Despite the premium postcode, the estimated median of $551,000 appears low because the rent-derived methodology likely captures the apartment and unit segment rather than the large riverside houses that define the suburb's reputation.

Estimated from rent (2025)
The estimated $551,000 median (rent-derived) likely understates the true detached house market, which runs substantially higher in a suburb where 35.7% of homes have four-plus bedrooms and 28.8% have three. Detached housing at 61.5% dominates, with apartments at 24.0% and semi-detached at 14.4% providing entry points. Monthly mortgage repayments of $3,000 produce a 32.5% mortgage-to-income ratio, above the stress benchmark, though actual household wealth (35.2% own outright) suggests many residents are not leveraged. Schools are exceptional: The Beehive Montessori (ICSEA 1,181), St Hilda's Anglican (ICSEA 1,171, 1,075 students), Mosman Park Primary (ICSEA 1,142, 403 students) and Iona Presentation College (ICSEA 1,141, 1,265 students) all rank in the top tier nationally.

For Investors
Renters at 34.7% provide a moderate tenant pool, but the 10.5% vacancy rate is high, suggesting some oversupply or seasonal letting patterns. At $300/week rent against a $551,000 estimated price, the gross yield of approximately 2.8% is low. Rent-to-income at 14.1% is remarkably low, indicating tenants in Mosman Park are financially comfortable. No development applications were recorded in 12 months, consistent with a built-out established suburb where new supply comes from knock-down-rebuild rather than greenfield development. The 25.1% turnover rate is moderate. Investors should note the rent-derived median likely misrepresents the true entry cost for detached houses, which would reduce yield further.

Detached houses comprise 61.5% of stock, with apartments at 24.0% and semi-detached at 14.4%. The bedroom profile spans widely: 35.7% four-plus, 28.8% three-bedrooms, 23.5% two-bedrooms and 12.0% studios/one-beds, reflecting the suburb's mix of large riverside homes and smaller walk-up apartments. Outright owners at 35.2% and mortgage holders at 30.1% together account for 65.3%, with renters at 34.7%. The estimated median of $551,000 is rent-derived and likely skews toward the apartment segment. Mortgage-to-income at 32.5% exceeds the stress threshold, but this is partially offset by the high outright-ownership rate and accumulated household wealth (IER decile 8).

How to read these comparisons
Phrases like "above the national average" reference the unweighted median across Australian suburbs with more than 1,000 residents, not population-weighted national figures. Suburb-level medians are more useful for ranking suburbs against each other; ABS census headlines are population-weighted (so dominated by Sydney and Melbourne) and can read very differently.
Current baseline (refreshed 2026-05-10): median age 40, university-educated 30.1%, born overseas 21.6%, average household size 2.5 people.
Data sources: ABS 2021 Census (demographics, income, tenure), state Valuer-General (house prices), Department of Jobs SALM (unemployment), ACARA (school ICSEA), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
