Karrinyup
Karrinyup pairs household income at the 91.7th percentile ($2,456/week) with SEIFA decile 10 readings on both IRSD and IRSAD, placing it among Perth's most advantaged northern suburbs. The estimated $608,000 median (rent-derived) appears modest against these income levels because 86.9% of stock is detached housing, meaning actual sales data, when available, would likely skew higher. Mining employs 8.0% of workers despite the suburban residential character, reflecting Perth's resource-economy reach. The senior share expanded 5.9 percentage points over the decade, the second-steepest aging trajectory in this batch, while the working-age share contracted 5.1 points.

For Investors
With only 18.9% renting, Karrinyup offers a shallow tenant pool, well below the national average. Median weekly rent of $450 against a $608,000 estimated median yields roughly 3.8% gross, reasonable for Perth. Rent growth of 24.3% over the decade is moderate. Mortgage-to-income at 24.3% and rent-to-income at 18.3% are both well below stress, indicating sustainable tenancy for those who find a rental. The vacancy rate of 6.1% is moderate. Overseas migration at +280 per year drives growth. With 48 DAs in 12 months, development activity is steady but not overwhelming. The 81.1% owner-occupier share means resale depends heavily on owner-occupier demand.

Demographics
University qualifications at 49.2% are 19.1 points above the national average, consistent with the IEO decile 9 reading. English ancestry dominates (3,969), with Italian (747) ranking 5th, a legacy of post-war European migration. Only 28.8% were born overseas (7.2 points above national), a moderate share for Perth. Average household size of 2.7 is slightly above national, and couples with children (3,903) significantly outnumber couples without (1,848). Italian (66), Mandarin (58) and German (38) lead non-English languages, reflecting a European-and-Asian migration mix. The volunteering rate of 20.1% is the second highest in this batch.

Owner-occupiers dominate: 40.4% own outright and 40.7% carry mortgages, leaving just 18.9% renting. The stock is overwhelmingly detached (86.9%), with semi-detached at 11.5% and apartments at 1.6%. Four-bedroom homes (51.7%) outnumber three-bedroom (38.8%), while studios/one-bedrooms are just 3.3%. The $608,000 estimated median provides entry well below comparable northern-suburbs competitors. Mortgage-to-income at 24.3% and rent-to-income at 18.3% are both comfortably below stress thresholds. Affordability held roughly stable (48.6% to 47.1%) over the decade, better than most Australian suburbs.

Economy & Employment
Healthcare (16.1%, 583 workers), Professional/Tech (14.1%, 512) and Education (13.8%, 502) form a diversified knowledge-economy core. Construction (10.1%, 365) and Mining (8.0%, 292) add a Perth-specific dimension. The Mining share, despite the suburban location, channels resource-sector incomes into the local economy, partly explaining why household incomes sit at the 91.7th percentile despite modest house prices. Professionals (1,668) and Managers (845) lead occupations. Unemployment at 4.2% is near the national baseline, and the participation rate of 61.5% is solid. The IER decile 10 confirms exceptional accumulated economic resources.

Population Forecast
+1.31%/yr
(+322 people/yr)
EstablishedPopulation grows at 1.31% per year (322 persons), with 19.4% growth over the decade. Overseas migration at +280 per year is the primary driver, with internal migration contributing a modest +56. Medium projections forecast 26,532 by 2031, up from 24,578 in 2025. The gentrification score of 39 (early signs) may reflect gentle infill densification rather than classic socio-economic displacement. However, the aging trajectory is significant: the senior share expanded 5.9 points while working-age contracted 5.1 points, the second-sharpest in this cohort. Real income grew just 4.4% over the decade, suggesting wage stagnation.

The estimated $608,000 median is accessible for the advantage level. Mortgage stress at 24.3% is comfortable. Car dependency (88.6%) is the main trade-off.
What is the median house price in Karrinyup?
The estimated median is $608,000 (rent-derived for 2025). Monthly mortgage repayments of $2,588 produce a mortgage-to-income ratio of 24.3%, well below stress. Median weekly rent is $450 with rent-to-income at 18.3%. Affordability held stable (48.6% to 47.1%) over the decade.
What schools are in Karrinyup?
Karrinyup has 5 schools, all above ICSEA 1,086. St Mary's Anglican Girls' School (1,151, 1,483 students) leads, followed by Karrinyup Primary (1,115, 561), Deanmore Primary (1,111, 486), Our Lady of Good Counsel (1,095, 152) and Newborough Primary (1,086, 344). All exceed the national benchmark substantially.
Is Karrinyup safe?
Crime data is not available for Karrinyup in the current dataset. The IRSD decile 10 (lowest disadvantage nationally) and IER decile 10 (highest economic resources) are strong safety indicators. The 81.1% owner-occupier share and 4.2% unemployment rate suggest a stable, low-risk environment.
Is Karrinyup good for property investment?
Gross yield is roughly 3.8% ($450/week on $608,000), reasonable for Perth. The 18.9% renter share limits the tenant pool. With 48 DAs in 12 months, supply additions are steady. Overseas migration at +280/year supports demand. Real income grew just 4.4% over the decade, so capital growth depends on continued population inflow rather than income-driven price uplift.
How is Karrinyup's population changing?
Population grew 19.4% over the decade, averaging 1.31% (322 people) per year, driven by overseas migration at +280/year. The senior share expanded 5.9 points while working-age contracted 5.1, the second-sharpest aging shift in this batch. Medium projections forecast 26,532 by 2031. The median age of 41 is 1 year above national.
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.
