Iluka
Two figures define this Joondalup coastal pocket: 97.6% of dwellings are separate houses and 86.4% carry four or more bedrooms, the kind of large detached stock that pushes household income to the 97.9th percentile nationally. The median age of 46 runs 6.0 years above the national figure, yet 53.3% of residents were born overseas, 31.7 points above national, an unusual pairing of an established, aging owner base with a strong migrant share. The suburb sits in SEIFA decile 10 on IRSAD, IRSD and economic resources, the top advantage tier, and decile 8 on education, across a compact 2.52 km2 footprint holding 5,669 people.

The $738,000 median house price stays well below Perth's premium coastal markets, which matters because buyers here are purchasing space rather than scarcity: 97.6% of dwellings are separate houses and 86.4% have four or more bedrooms, so a typical purchase is a large family home. Monthly mortgage repayments average $2,600 against household incomes in the 97.9th percentile, producing a mortgage-to-income ratio of just 19.1%, far below the 30% stress threshold. That comfort is why 53.4% of residents carry a mortgage while only 7.9% rent. Owner-occupiers dominate because the stock suits settled families, with an average household size of 3.0, which is 0.5 above the national figure, rather than downsizers or investors chasing yield.

Owner-occupiers dominate because the stock suits settled families, with an average household size of 3.0, which is 0.5 above the national figure, rather than downsizers or investors chasing yield.
For Investors
The renter share is only 7.9%, one of the thinnest tenant pools you will find, which constrains the investment case from the start. Weekly rent of $635 against the $738,000 median implies a gross yield near 4.5%, healthier than premium suburbs, but the 3.2% vacancy rate sits in a tight band with limited rental supply because the market is built for owner-occupiers. Development is minimal, with just 3 applications lodged in 12 months, mostly a single new dwelling and minor changes rather than new rental supply. With 53.4% on a mortgage and turnover at 19.5%, stock rarely trades, so investors compete with families for the same large detached homes rather than buying purpose-built rentals.

Demographics
The median age of 46 is 6.0 years above national, and the profile leans toward established families: average household size is 3.0, which is 0.5 above the national figure, and couples with children (2,003 families) outnumber couples without children (1,286). Overseas-born residents reach 53.3%, fully 31.7 points above national, with ancestry led by English (2,827), Irish (654) and Scottish (602), and a notable South African community (291). That migrant weight shows in the languages: Afrikaans (88 speakers) leads non-English use, ahead of Mandarin (27) and Arabic (23). University qualifications at 39.4% run 9.3 points above national, consistent with the professional and managerial workforce that fills these large homes.

Tenure
Tenure is heavily owner-skewed: 53.4% carry a mortgage, 38.7% own outright, and only 7.9% rent, a far lower rental share than most metropolitan suburbs. The stock is almost entirely detached, with separate houses at 97.6% and apartments just 1.3%, and it is large: 86.4% of dwellings have four or more bedrooms while only 3.3% are two-bedroom. The $738,000 median house price, estimated from 2025 rents, is modest given household incomes in the 97.9th percentile, which is why mortgage-to-income sits at 19.1% and rent-to-income at 20.2%, both below stress thresholds. The combination of big homes and comfortable serviceability explains the high mortgage take-up rather than outright ownership among working-age families.

Transport to Work
Daily life is car-centred: 84.5% drive to work while only 7.6% use public transport and 1.4% walk or cycle, above the typical car reliance because the suburb is detached and low-density at 2,249 people per km2. The area earns decile 10 on IRSAD, the top advantage tier nationally, and decile 10 on IRSD for relative disadvantage, so very few residents face deprivation, with only 2.6% (142 people) needing daily assistance despite the older median age of 46. Volunteering runs at 15.1%. No schools are recorded inside the 2.52 km2 boundary in this dataset, so families rely on institutions in neighbouring Joondalup suburbs, a practical trade-off in a compact coastal pocket.

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.
