Banjup
Household income in the 92.4th percentile nationally, yet a median house price of $552,000 still sits within reach of many buyers: that combination defines Banjup's appeal. The suburb is almost entirely detached housing, with 99.1% separate houses and 77.9% of dwellings having 4 or more bedrooms, catering firmly to families rather than investors chasing density. With a population that grew 53.2% over the past decade and an active gentrification score of 50, Banjup sits in an unusual position: established wealth arriving into a suburb still priced below what the incomes would suggest in comparable areas.

The median house price of $552,000 is the entry point for one of WA's most detached-dominant suburbs, where 99.1% of dwellings are separate houses and 77.9% have 4 or more bedrooms. Monthly mortgage repayments average $2,100, producing a mortgage-to-income ratio of 19.3%, comfortably below the 30% stress threshold even at a household income percentile of 92.4 nationally. Outright owners represent 44.3% of households, a high figure that points to long-held tenure rather than churn, while only 13.0% rent. The 4-bedroom dominant stock means buyers tend to be families trading up, and competition for larger lots keeps prices firmer than suburb-level averages might suggest.

The 4-bedroom dominant stock means buyers tend to be families trading up, and competition for larger lots keeps prices firmer than suburb-level averages might suggest.
For Investors
A 13.0% renter share is low compared to most suburban markets, which limits tenant pool depth. Weekly rent of $450 against a $552,000 median implies a gross yield around 4.2%, reasonable by WA standards. The vacancy rate of 7.8% is elevated and warrants caution, suggesting supply currently outpaces rental demand in the area. On the demand side, net internal migration adds 470 residents a year and overseas inflow contributes 363, providing a structural tailwind. The 10-year population change of 53.2% confirms the corridor is growing rapidly, and medium forecasts project the broader area reaching 31,684 by 2031. Low development activity inside the suburb itself limits new competing supply.
Demographics
The median age of 42 sits 2.0 years above the national figure, and the share of seniors rose 4.8 points over the decade while the young-adult share fell 4.1 points, a clear aging trajectory. Overseas-born residents make up 31.5% of the population, which is 9.9 percentage points above the national average. Ancestry is led by English (483), Scottish (116), Chinese (106) and Italian (104). The top non-English languages are Mandarin (25 speakers), Punjabi (12) and Italian (12). Average household size of 3.0 is 0.5 above national, consistent with the family-oriented, large-dwelling profile. University qualifications reach 32.4%, which is 2.3 points above national, clustering the workforce toward professional and managerial roles.

Tenure
Tenure is strongly ownership-oriented: 44.3% own outright, 42.7% carry a mortgage and only 13.0% rent. These figures sit above typical suburban benchmarks nationally, because 80.6% of residents have remained in Banjup for at least five years, suppressing turnover. The dwelling mix is almost entirely separate houses at 99.1%, with 77.9% having 4 or more bedrooms. Three-bedroom homes make up just 19.7%, meaning the suburb skews large. The median house price of $552,000 is estimated from 2025 rental data. Rent-to-income runs at 17.9%, below the stress level, while mortgage-to-income at 19.3% is similarly manageable given household income in the 92.4th percentile nationally.

Population Forecast

EstablishedPopulation grew 53.2% over the past decade, one of the stronger medium-sized suburb growth rates in WA. The broader SA2 area reached 26,778 residents in 2025 and medium forecasts project 31,684 by 2031 at 3.29% annual growth. Internal migration contributes 470 net residents a year and overseas inflow adds 363, both substantial. The gentrification signal is active, scoring 50, driven by accelerating overseas-born share (21% to 48%) and sustained inbound migration. Real income growth was negative at -5.2% over the decade, suggesting that inbound residents are not universally higher-income arrivals; affordability improved from 46.2% in 2011 to 40.6% in 2021, creating room for further price growth if income trends stabilise.

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).
