Yarrabilba
Population grew 2,268.6% over the past decade, the most extreme greenfield expansion in the dataset, transforming Yarrabilba from a near-empty rural area into a suburb of 15,803 in 2025. At a median age of 25, fifteen years below the national figure, this is Australia's youngest major suburb, shaped by first-home-buyer families with 75.6% four-plus bedroom stock and an average household size of 3.1. Yet the IRSAD decile 2 rating reveals that these young families are starting from a low socioeconomic base: 15.8% university rates run 14.3 points below the national average, unemployment sits at 8.4%, and IEO decile 2 is among the lowest nationally.

Without reliable median price data, buyers must gauge affordability through mortgage repayments: the $1,700 monthly median produces a mortgage-to-income ratio of 24.8%, below the 30% stress threshold but tighter than the national average for greenfield estates. Four-plus bedroom homes dominate at 75.6% of stock, the highest share in the dataset, reflecting the young-family housing purpose. Three-bedroom stock at 20.7% provides limited options for smaller households. Detached houses account for 92.4% with just 7.2% semi-detached. The 5.7% outright ownership rate is the lowest in the dataset, because virtually everyone has purchased recently with a mortgage. Household income at the 52nd percentile is only marginally above the national median.

For Investors
Renters make up 61.6% of households, one of Australia's highest rates for a detached-housing suburb, a consequence of estate-phase build-to-rent and young families renting before buying. Weekly rent of $375 at a 5.3% vacancy rate is moderate. Rent grew 25.0% over the decade, outpacing real income growth of 9.6%. Population growth at 5.73% annually (905 persons) is among the fastest in Australia, driven almost entirely by internal migration averaging 906 per year, with overseas arrivals contributing just 55. With 94 DAs in 12 months, predominantly new dwelling construction, supply is still expanding rapidly, which may prevent rent or price acceleration.

Tenure
Tenure shows 5.7% outright owners, 32.6% mortgage holders and 61.6% renters, an extreme renter-dominant split unusual for a detached-housing suburb. The renting pattern reflects the estate lifecycle: many families rent new homes before purchasing in the same area. Four-plus bedrooms at 75.6% and three-bedrooms at 20.7% together account for 96.3% of stock, exclusively family-sized housing. At 92.4% detached houses, the housing fabric is pure greenfield estate. The 24.8% mortgage-to-income ratio sits below the stress threshold. The rent-to-income ratio of 23.7% is manageable at the 52nd percentile household income. Average household size of 3.1 is above the national average.

Professionals (480) rank fifth. The IEO decile 2 confirms very low education and occupation advantage. The 8.4% unemployment rate is well above the national average, and the 61.8% participation rate reflects the young working-age cohort. Construction's 12.2% share is directly linked to ongoing estate development within and around the suburb.

(+905 people/yr)
High GrowthPopulation surged 2,268.6% over the past decade, from near-zero to 15,803 in 2025, with projections reaching 20,110 by 2031 at 5.73% annually (905 persons per year). Growth is driven almost entirely by internal migration averaging 906 per year, the highest internal flow in the dataset, with overseas arrivals at just 55. The 94 DAs in 12 months, dominated by new single-storey dwellings, confirm the estate is still in active buildout phase. The trajectory is rejuvenating rather than aging: the young share grew 11.3 points and the senior share dropped 5.3 points. Rent grew 25.0% and real income grew 9.6% over the decade.

Is Yarrabilba safe?

However, the very young median age of 25 and family-dominant household composition (couples with children outnumber those without by 4 to 1) may moderate crime risk.

Population growth at 5.73% annually (905 persons) is among Australia's fastest, driven by internal migration. The 94 DAs in 12 months mean significant new supply is entering the market, which may cap rent and price growth.

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.
