Mount Austin
At 46.5% renting, Mount Austin has a more tenant-oriented profile than its 90.0% separate-house form might suggest. The suburb contains 4,035 residents across 2.57 square kilometres, with a density of 1,572.2 people per square kilometre and a median age of 37. Household income sits at the 18.3rd percentile, below higher-income suburban benchmarks, which helps explain the mix of established renters and modest-cost detached housing. Compared with nearby Tolland and Turvey Park, buyers should compare tenure, street conditions and access carefully rather than assume similar value. The 2.3-person average household is 0.2 below the national comparison, pointing to smaller households despite the strong family-house format.

Mount Austin is suited to buyers seeking detached housing with a practical affordability focus. Separate houses account for 90.0% of dwellings, while 55.7% contain 3 bedrooms and 22.8% contain 4 or more, giving families more choice than apartment-heavy areas. The monthly mortgage figure is $1,148, compared with weekly rent of $250, while mortgage payments equal 23.6% of household income and remain below the 30% stress threshold. Household income is $1,124 per week and sits at the 18.3rd percentile, so deposit size, repair costs and rate rises matter more than simply targeting a larger block. A current sales comparison is essential because no house-price median is supplied. The 2.3-person household size is lower than the national comparison by 0.2, which may suit buyers wanting established homes without requiring a large family.

For Investors
Mount Austin has a sizeable rental base, with 46.5% of occupied dwellings rented and weekly rent recorded at $250. That creates a broad tenant pool, but the 8.0% vacancy rate is a caution because available stock can take longer to lease than in tighter markets. The useful comparison is vacancy against achievable rent, not rent alone. Eleven development applications in 12 months point to ongoing small-scale alterations rather than a major new dwelling pipeline, so investors should focus on existing houses, maintenance and tenant appeal. Housing is 90.0% separate houses, which can support family demand, while 80.3% of residents stayed at the same address and turnover was 19.7%. This stability can reduce leasing churn, although the 18.3rd-percentile household income profile makes pricing discipline important.

Tenure
Mount Austin's housing stock is strongly detached, with 90.0% separate houses, 6.8% semi-detached dwellings and 3.0% apartments. Three-bedroom homes make up 55.7% of dwellings, while 4 or more bedrooms account for 22.8%, so the suburb is more family-house oriented than apartment-focused districts. Tenure is split between 24.2% owned outright, 28.7% mortgaged and 46.5% rented, meaning renters outnumber outright owners and mortgage holders combined. Compared with apartment-oriented suburbs, this form provides more yard and renovation potential but can bring higher upkeep costs. The weekly rent is $250 and mortgage payments are $1,148 per month; rent absorbs 22.2% of household income and mortgages 23.6%, both below common stress markers. A current sale median and price-to-income ratio should be checked before purchase because household income is only at the 18.3rd percentile.

Transport to Work
Mount Austin is a car-dependent suburb, with 83.1% of commuters driving, compared with 0.7% using public transport and 2.4% walking or cycling. A further 4.6% work from home, so access to employment and services by car remains important because local active and public transport use is limited. Mount Austin Public School provides 1 government primary school option within the suburb; families should check enrolment zones and nearby school choices against the exact address. The 2.57-square-kilometre area and density of 1,572.2 people per square kilometre create a compact residential setting, while the 2.3-person average household suggests demand from smaller families, couples and single-person households. No local crime rate is available for a reliable safety comparison, so buyers and renters should review current NSW Police information and visit streets at different times before deciding.

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.
