Demographics

The median age of 31 runs 9.0 years below the national figure, and the family structure confirms the young profile: 3,402 families are couples with children against just 784 couples with no children, or 14.2%. Average household size is 3.2 people, 0.7 above national, consistent with the large 4-plus-bedroom homes. Overseas-born residents reach 33.3%, which is 11.7 points above national, with English ancestry leading at 1,915 followed by Indian and Irish at 524 each. University qualifications stand at 38.6%, 8.5 points above the national figure, pointing to an educated working-age base. The top non-English languages are Punjabi (151 speakers), Malayalam (93) and Hindi (51), and Hinduism is the second religion at 288 residents behind Christianity at 2,801, reflecting recent South Asian migration into a fast-growing area.

Tenure tilts heavily toward recent buyers: 50.3% carry a mortgage, 40.2% rent and only 9.6% own outright, a split typical of a young, high-growth suburb where most owners are still paying down loans. The stock is overwhelmingly detached at 95.5% separate houses with 4.5% semi-detached and effectively no apartments, and 84.9% of dwellings have 4 or more bedrooms. The median house price of $552,000 stays affordable relative to the 92.1st-percentile household income, giving a price-to-income ratio that keeps both mortgage stress (20.1%) and rent stress (16.5%) below threshold. The 4.6% vacancy rate is moderate. Affordability has improved over the decade, with the measure easing from 42.8% in 2011 to 35.2% in 2021, a rare direction in Australian housing and a function of new supply meeting demand.

Community Profile

Economy & Employment

The workforce concentrates in stable public-facing sectors: Healthcare leads at 19.7% (461 workers), Public Administration follows at 14.1% (331) and Education at 10.3% (242), with Professional/Tech at 8.4% and Retail at 7.3%. By occupation, Professionals (800) and Managers (470) dominate, which aligns with the IEO score of decile 8 for education and occupation. Unemployment is low at 4.8%, full-time employment runs at 69.9% and participation is high at 73.6%, well above what an aging suburb would post, because the median age of 31 keeps most residents in the labour force. The IER score reaches decile 10, the top tier for economic resources, reflecting strong household incomes in the 92.1st percentile. One nuance: real income growth was slightly negative at -1.2% over the decade, so rising prosperity here comes from population scale rather than per-capita gains.

Transport to Work

Car dependence is high, with 89.2% of residents driving to work, well above the national rate, while public transport carries just 3.4% and 1.2% walk or cycle, a pattern expected for a low-density outer suburb at 1,110.9 residents per km2 across 5.48 km2. The suburb scores decile 10 on the IRSD index of relative disadvantage and decile 9 on IRSAD, both near the top advantage tier, meaning very few residents face deprivation. Only 3.0% (179 people) need daily assistance, low partly because the median age of 31 skews young. Volunteering runs at 13.4%. No schools are recorded inside the suburb boundary in this dataset, so families rely on institutions in neighbouring suburbs, a practical trade-off in a young, fast-expanding area where infrastructure is still catching up to the 161.7% decade population rise.

Population Forecast

Few suburbs match the 161.7% population increase Augustine Heights recorded over the past decade, and the momentum continues: trend forecasts add about 454 residents a year at 4.46% annually, lifting the medium projection from 11,147 in 2026 toward 13,417 by 2031. Overseas migration of roughly 120 a year is the primary driver, supplemented by net internal inflow of 26 a year, an unusual combination because most outer suburbs lose residents internally. The gentrification stage reads as new development rather than displacement, meaning growth comes from fresh housing supply rather than the upgrading of existing stock. The young-resident share dipped 1.9 points and the senior share rose 2.6 points, a mild maturing of an otherwise youthful base. Affordability improved from 42.8% to 35.2% across 2011 to 2021.
