Cornubia
With 67.4% of dwellings containing four or more bedrooms and 93.7% being separate houses, Cornubia is shaped around larger households rather than apartment living. Its 7,810 residents have a median age of 40, while household income sits at the 89.2 percentile, above the national median. University attainment is 32.2%, or 2.1 percentage points above the national figure. The suburb's 55.4% mortgage-held share supports its mortgage-belt identity, while a 7.4-point rise in the senior share points to an aging trajectory. Near Shailer Park and Loganholme, Cornubia suits buyers seeking space, though car dependence is higher than in transit-oriented suburbs.

Homebuyers in Cornubia are choosing low-density, family-oriented stock: 93.7% of dwellings are separate houses, 67.4% have four or more bedrooms and only 0.4% are apartments. That mix gives buyers more space than in denser Logan City markets, but it narrows the choice for people wanting compact or low-maintenance homes. A monthly mortgage figure of $2,054 equals 20.2% of household income, while the median weekly rent is $440. Because 55.4% of households already hold a mortgage, purchasers should test repayments against rate rises, insurance and maintenance. A current median house price is not available, so compare recent sales for homes with similar bedroom counts and locations.

A current median house price is not available, so compare recent sales for homes with similar bedroom counts and locations.
For Investors
Investor conditions are defined by owner occupation: only 13.2% of households rent, compared with 55.4% carrying a mortgage and 31.0% owning outright. That smaller rental pool can support demand from established households, but may limit tenant turnover compared with apartment-heavy areas. Weekly rent is $440 and vacancy is 4.0%, useful starting points for assessing leasing depth, although no purchase median is available for a reliable gross-yield calculation. Development activity totals 1,397 records over 12 months. Examples include an awning, vegetation clearing and a swimming pool barrier, so the count is broader than new dwellings. Overseas migration is the primary growth driver and may gradually widen renter demand.

Mortgage costs represent 20.2% of household income, higher than the 18.7% rent share, while weekly rent is $440.

Transport to Work
Daily life in Cornubia is car-led: 72.2% of commuting residents drive, compared with 1.7% using public transport and 1.2% walking or cycling. Working from home accounts for 21.1%, which can reduce some weekday trips but does not replace a private vehicle for many errands. Two local schools are identified, both Catholic non-state providers, so families should check exact enrolment zones, year levels and travel times. Socioeconomic settings are above the midpoint, with IRSAD at decile 8 and IER at decile 10, the highest decile. No suburb crime rate is available; use current Queensland Police information when comparing streets and time periods. The low-density layout suits larger households, but transport convenience is lower than in rail-oriented suburbs.

Cornubia suits households seeking space, with 93.7% separate houses and 67.4% containing four or more bedrooms. Household income is at the 89.2 percentile, above the national median, but 72.2% drive to work, so it is less transit-friendly than rail-oriented suburbs.
What is the median house price in Cornubia?
A current median house price is not available for Cornubia. Buyers can compare homes using the $2,054 monthly mortgage figure, $440 weekly rent, 93.7% separate-house share and recent sales for similar bedroom counts rather than relying on a broad average.
What schools are in Cornubia?
Cornubia has 2 identified local schools: Chisholm Catholic College and St Matthew's School. Both are Catholic, non-state providers, so families should compare enrolment zones, year levels and travel times, which matter more than the suburb label.

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 education open registers (school locations), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
