For Buyers

Homebuyers are choosing a low-density market where 100.0% of dwellings are separate houses, 51.7% have 3 bedrooms and 37.5% have 4 or more. A $1,742 monthly mortgage represents 20.2% of household income, while outright ownership is 24.6% and mortgage ownership is 66.8%. Compared with apartment-oriented suburbs, Cockatoo suits buyers prioritising land and space over compact entry pricing.

For Investors

Investor conditions are shaped by a small rental pool: only 7.7% of households rent, the weekly median rent is $370 and vacancy is 5.5%. That vacancy rate gives tenants more choice than a tighter market, while the limited rental share can reduce turnover and make each listing more consequential. Development activity was limited to 4 applications in 12 months, so supply expansion appears modest. Overseas migration is the primary growth driver. Compared with high-density rental markets, Cockatoo relies more on detached-house demand and long-term capital growth.

Transport to Work

Day-to-day life is car-oriented: 72.3% drive to work, compared with 1.2% who walk or cycle, while 22.4% work from home. That pattern suits larger blocks and dispersed services but makes access to jobs and shopping more dependent on a vehicle. Cockatoo has 1 local school, Cockatoo Primary School, a government primary campus. Families should check enrolment zones against the exact address because boundaries can cross nearby communities. Crime totalled 231 incidents, including 110 property and deception offences, 52 crimes against the person and 40 justice procedures offences, for a rate of 52.4 per 1,000 residents. Social conditions are comparatively strong, with IRSAD decile 7 and IRSD decile 9; the latter is higher than the former. Volunteering is 16.2%, supporting local participation.

Frequently Asked Questions

What schools are in Cockatoo?

Cockatoo Primary School is the local school listed, providing 1 government primary option. Families seeking secondary schooling or a different sector should check the exact enrolment zone and travel options, because school access can differ from nearby Emerald and Gembrook. Compare address-level boundaries before buying.

Is Cockatoo safe?

Cockatoo recorded 231 offences, equal to a reported rate of 52.4 per 1,000 residents. Property and deception offences were the largest category at 110, higher than crimes against the person at 52. Safety can vary by street and time, so compare local conditions and standard precautions rather than relying on one annual rate.

Is Cockatoo good for property investment?

Investment prospects are mixed. The $370 weekly rent and 5.5% vacancy rate provide a basis for rental analysis, but only 7.7% of households rent, limiting the size of the tenant pool. Prices rose 126.1% from 2013 to Oct-Dec 2025 yet sat 1.3% below peak, so compare cash flow with long-term growth expectations.

How is Cockatoo's population changing?

Cockatoo's current population is 4,408, with forecast growth running at 0.37% a year. The wider area's 10-year population change is 6.4%, and the trajectory is Aging, with the senior share up 4.9 points. Overseas migration is the primary driver, so change is likely to be gradual compared with a high-growth corridor.

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), Valuer-General Victoria (house prices), 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.
