Jane Brook
Household income in Jane Brook sits in the 89.4th percentile nationally, yet housing costs stay below what that income would imply, because the suburb still carries a median house price of $533,000 and a mortgage-to-income ratio of 19.6%. That combination explains its mortgage-belt identity: 61.5% of residents are paying off a home, well above the national average for owner-occupiers with debt. The area spans 5.23 sq km with a density of 702 residents per km2, and its stock is almost entirely detached houses at 99.7%, making it one of WA's most uniformly single-family suburban areas.

Estimated from rent (2025)
The median house price of $533,000 gives buyers in Jane Brook access to a predominantly large-lot market, where 85.7% of dwellings have four or more bedrooms. That figure sits well above the national average for four-plus-bedroom stock. Monthly mortgage repayments average $2,000, and the mortgage-to-income ratio of 19.6% is below the 30% stress threshold, meaning buyers at median price and median income have comfortable headroom. The renting share is low at 9.1%, so competition among owner-occupiers dominates purchase decisions. Outright owners account for 29.4% of tenure, suggesting a cohort of longer-held properties that may list less frequently.
For Buyers
The median house price of $533,000 gives buyers in Jane Brook access to a predominantly large-lot market, where 85.7% of dwellings have four or more bedrooms. That figure sits well above the national average for four-plus-bedroom stock. Monthly mortgage repayments average $2,000, and the mortgage-to-income ratio of 19.6% is below the 30% stress threshold, meaning buyers at median price and median income have comfortable headroom.

For Investors
Jane Brook's investment fundamentals are modest rather than compelling. The renting share is only 9.1% compared to the national average of roughly 30%, which means the tenant pool is thin and rental vacancies are harder to absorb. Vacancy sits at 4.5%, above the 3% threshold generally associated with balanced markets. Weekly rent of $440 against a $533,000 median implies a gross yield around 4.3%, reasonable by WA standards. Rent grew 3.1% over the period. Annual net overseas migration of 55 people and internal migration of 15 provide modest demand support, and the population is growing at 0.75% per year, adding around 59 residents annually.

Demographics
The median age of 39 is 1.0 year below the national figure, making Jane Brook slightly younger than the national average. Overseas-born residents account for 22.8%, which is 1.2 percentage points above national. Ancestry is heavily Anglo-Celtic: English (1,566 residents) is dominant, followed by Scottish (386), Irish (300) and Italian (300). The average household size of 2.9 is 0.4 above national, consistent with the large-dwelling, family-oriented stock. University qualifications at 23.9% fall 6.2 percentage points below the national figure, so the suburb skews toward trade and clerical employment rather than professional knowledge work. The volunteering rate of 13.2% indicates moderate civic engagement.

Tenure
Jane Brook's housing stock is almost entirely detached houses, with 99.7% separate dwellings and only 0.3% apartments. This compares to the national average where apartments and semi-detached homes make up roughly 30% of stock. The four-plus-bedroom category dominates at 85.7%, reflecting the suburb's family-oriented profile on larger lots. Tenure tilts toward buyers: 29.4% own outright, 61.5% hold a mortgage, and just 9.1% rent. The mortgage-to-income ratio of 19.6% and rent-to-income of 18.7% both sit below the 30% stress threshold, so housing costs are manageable relative to local incomes at the 89.4th household income percentile. Nine development approvals in the past 12 months suggest limited new supply.

Economy & Employment
Healthcare leads local employment at 14.1% (184 workers), followed by Education at 12.8% (167) and Mining and Construction at 9.9% each (129 workers apiece).

By occupation, Professionals account for the largest share (374 workers), followed by Clerical/Admin (339) and Managers (251). The full-time employment rate of 65.6% and participation rate of 69.2% are solid, with unemployment at 4.3%. SEIFA scores show an IRSD decile of 4 and IRSAD decile of 4, meaning the suburb ranks below average nationally on both disadvantage and advantage-disadvantage measures, despite income at the 89.4th percentile. The IER (economic resources) decile of 7 is the one stronger indicator.

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.
