Mount Crosby
Household income in the 97.1st percentile nationally tells you what Mount Crosby is before the other numbers do.

Only 6.9% of households rent, compared to national averages closer to 30%, because most residents have committed to ownership here long-term.

The median house price sits around $595,000, estimated from 2025 rental data, placing Mount Crosby well below comparable high-income suburbs in the Brisbane metro. Monthly mortgage repayments average $2,095, and mortgage-to-income at 16.2% signals no financial stress, which is low compared to most urban markets. The stock is almost entirely separate houses at 99.5%, with 70% having four or more bedrooms, meaning buyers get generous family-sized homes. Turnover is low with 85.5% of residents staying put in the five years to the census, so stock rarely hits the market. Only 62.3% carry a mortgage while 30.7% own outright, suggesting a mix of long-established and newer owner-occupiers who bought at affordable price points.

For Investors
At 6.9% renting, Mount Crosby is one of the thinner rental markets in the Brisbane region, well below the national average. Weekly rent is $478, which against a $595,000 median implies a gross yield around 4.2%, modest but better than inner-city alternatives. The vacancy rate of 5.1% is elevated for such a low-renter suburb and points to limited turnover rather than active tenant demand. Only 4 development applications were lodged in the past 12 months, reflecting the low-density, established character and limited infill opportunity. The investment case depends on capital appreciation from income-rich buyers priced out of inner suburbs, not yield or rental volume.

Demographics
The median age of 42 is 2.0 years above the national figure, consistent with an established family and pre-retirement cohort rather than a young professional intake. University qualifications reach 44.9%, which is 14.8 points higher than the national average, placing Mount Crosby in the top tier of educated suburbs relative to its size. Overseas-born residents account for 22.2%, which is 0.6 points above national and reflects a modest but present international mix. Ancestry is strongly Anglo-Celtic: English leads with 871 residents, followed by Irish (274) and Scottish (242). Average household size of 3.1 is 0.6 above the national figure, driven by the dominance of couples-with-children households (849 of 1,680 families), reinforcing the family-suburb profile.

Four-plus bedroom homes account for 70% of the stock, with three-bedroom homes at 25.6%, and smaller configurations virtually absent.

Monthly mortgage repayments of $2,095 against a household income in the 97.1st percentile nationally produce a mortgage-to-income ratio of 16.2%, well below the 30% stress threshold. Rent-to-income is similarly comfortable at 16.0%. The combination of large homes, low financial stress, and minimal renter presence defines Mount Crosby as a committed ownership suburb.

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.
