Casey
A 334.3% population jump over ten years marks Casey as one of Canberra's newest residential frontiers, and the supporting numbers explain why. The median age of 32 sits 8.0 years below the national figure, household income reaches the 94.6th percentile nationally, and 49.6% of adults hold university qualifications, 19.5 points above national. The suburb scores decile 10 on both IRSAD and IRSD, the top advantage tier, alongside decile 9 on the income and economic-resources indexes. Housing is overwhelmingly detached at 75.6%, with 44.7% of dwellings carrying four or more bedrooms, which fits a young, family-forming base where 58.5% of households are paying off a mortgage.

Estimated from rent (2025)
The estimated median house price of $660,000 is modest relative to Casey's incomes, since household earnings rank in the 94.6th percentile nationally. That gap is why mortgage-to-income runs at just 18.7%, well below the 30% stress threshold, leaving buyers genuine borrowing headroom. The stock suits families rather than downsizers: 75.6% are separate houses and only 1.9% are apartments, while 44.7% of dwellings have four or more bedrooms and another 38.0% have three. Monthly mortgage repayments average $2,167. With 58.5% of households on a mortgage against just 11.7% owning outright, Casey is a buying market dominated by recent purchasers rather than long-held, debt-free owners, consistent with a suburb that grew 334.3% in a decade.

For Investors
Renters make up 29.8% of Casey households, a smaller share than the mortgage-paying 58.5%, so the tenant pool is shallower than in established suburbs. Weekly rent of $502 against the $660,000 median implies a gross yield near 4.0%, healthier than inner-city Canberra norms because the entry price is lower. The 3.9% vacancy rate sits close to a balanced market, neither tight nor oversupplied. Demand support leans on overseas migration adding 55 residents a year, partly offset by net internal outflow of 88. Development is thin at only 3 applications in 12 months, all minor works on existing dwellings, so new rental supply is limited and competition for tenants stays moderate. Forecast annual population growth of 5.33% underpins the long-run case, but yield rather than turnover is the near-term draw.

Demographics
Casey skews young: the median age of 32 runs 8.0 years below the national figure, and the growth trajectory reads expanding across all ages rather than aging. Overseas-born residents reach 32.3%, which is 10.7 points above national, and university qualifications at 49.6% sit 19.5 points higher. Ancestry leads with English (1,735) and Irish (569), but Indian (521) is the third largest, and the top non-English languages are Punjabi (114), Mandarin (104) and Urdu (82), pointing to a strong South Asian presence. Average household size is 2.9, which is 0.4 above national, because families dominate: 3,267 households are couples with children against just 989 couples without. Beyond Christianity (2,587 residents), Hinduism (434) and Islam (385) are the next largest faiths, reflecting that migrant mix.

Tenure
Tenure tilts heavily toward mortgages: 58.5% of households are paying off a loan, 29.8% rent and only 11.7% own outright, a profile typical of a young suburb where most buyers are still mid-repayment. The stock is 75.6% separate houses and 22.5% semi-detached, with apartments at just 1.9%, so density stays low despite 2,467.5 residents per km2 across the 2.62 km2 footprint. Dwellings run large: 44.7% have four or more bedrooms and 38.0% have three, against only 15.9% two-bedroom homes. The estimated $660,000 median is affordable relative to 94.6th-percentile incomes, which keeps mortgage-to-income at 18.7% and rent-to-income also at 18.7%, both comfortably below the 30% stress line and well under the strain seen in pricier markets.

Economy & Employment
Casey's workforce is anchored to the public sector: Public Admin alone employs 32.0% (911 workers), reflecting the suburb's Canberra location and proximity to government jobs. Healthcare follows at 12.8% (365), Professional/Tech at 11.6% (329), Education at 9.9% (281) and Construction at 6.9% (197). By occupation, Professionals (1,032) and Managers (661) dominate, which aligns with the decile 9 IEO score for education and occupation. Unemployment is low at 3.7% and the full-time rate reaches 74.2%, while labour-force participation runs at 77.0%, above what older suburbs achieve because the median age is only 32. The decile 9 economic-resources score is one tier below the decile 10 advantage rating, a gap explained by the 58.5% of households still carrying mortgage debt.

Transport to Work
Casey is heavily car-dependent: 91.2% of commuters drive, while just 1.2% use public transport and 1.4% walk or cycle, a reliance well above the national norm that reflects its outer-Gungahlin position with limited transit. The suburb scores decile 10 on IRSAD, the top advantage tier nationally, and decile 10 on IRSD for relative disadvantage, so very few residents face deprivation, with only 2.8% (174 people) needing daily assistance despite a fast-growing population. Volunteering runs at 13.6%. No schools are recorded inside the 2.62 km2 boundary in this dataset, so families with children, who head 3,267 of the households here, rely on schools in neighbouring Gungahlin suburbs, a practical trade-off for a newly built area.

High GrowthFew suburbs grow this fast: Casey expanded 334.3% over ten years and is forecast to add 5.33% annually, or about 359 residents a year. Historical counts climbed from 6,635 in 2023 to 6,731 in 2025, and the medium projection lifts the population from 7,974 in 2026 to 9,771 by 2031, a near-continuous build-out classified as new development. Overseas migration is the primary driver at 55 net arrivals a year, partly offset by net internal outflow of 88, so international arrivals more than carry the growth. The gentrification stage reads not gentrifying because the suburb is being built new rather than transformed from older stock. Affordability improved from 44.1% in 2011 to 37.2% in 2021, easing the cost burden as supply expanded.

Is Casey good for property investment?
Rent of $502 a week against a $660,000 median gives a gross yield near 4.0%, stronger than inner Canberra, and the vacancy rate is a balanced 3.9%. Renters are 29.8% of households, a smaller pool than the 58.5% on mortgages, so demand is steady rather than deep.
How is Casey's population changing?
Casey grew 334.3% over ten years and is forecast to expand 5.33% annually. The population is projected to rise from 7,974 in 2026 to 9,771 by 2031, driven mainly by overseas migration of 55 net arrivals a year against a net internal outflow of 88.

About 32.3% of residents were born overseas, 10.7 points above the national figure. English dominates, but Punjabi (114 speakers), Mandarin (104), Urdu (82) and Hindi (58) are the most common non-English languages, reflecting a notable South Asian community.
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.
