Mount Annan
Detached housing defines Mount Annan more than almost anything else: 96.1% of dwellings are separate houses and 74.2% have 4 or more bedrooms. That makes it a family-scale part of the Camden corridor compared with nearby Narellan and Currans Hill, with bigger households at 3.2 people, 0.7 above the national average. Incomes are also high, with household income in the 92.3 percentile, while the median age of 34 sits 6 years below national, so the suburb is younger but already moving into an aging family phase.

The median house price is $1,095,000, while the 2025 price series reached $1,146,000 after a 12.3% rise from 2024.

Compared with more compact centres nearby, Mount Annan suits buyers prioritising bedrooms, garages and family yards over walkability.

For Investors
Mount Annan is a lower-churn family rental market because renters are only 19.8% of households while mortgaged owners are 57.1%. The median rent is $480 a week and vacancy is 2.3%, giving investors a steadier but less renter-dense pool than apartment-led markets. Development activity is meaningful, with 36 lodgements in 12 months and recent examples including secondary dwellings and alterations. Rent growth of 21.1% supports cash-flow improvement, but net internal migration of -181 a year means demand relies more on overseas migration at 108 a year.

The latest price series has the median at $1,146,000 in 2025, up from $1,020,500 in 2024, a 12.3% rise, with the latest quarter also the peak and 0.0% below peak. The broader house indicator is $1,095,000. With 96.1% separate houses and 74.2% of homes at 4 or more bedrooms, scarcity of smaller stock keeps downsizer and entry options limited.

Economy & Employment
The local workforce leans into stable service and public-facing sectors: healthcare employs 634 people, education 592, construction 462, public admin 361 and manufacturing 309. Occupations are led by professionals at 1,162, clerical/admin at 996 and managers at 866, which helps explain household income sitting in the 92.3 percentile. SEIFA is uneven in a useful way: IEO is decile 5, but IER is decile 10, while IRSD and IRSAD are both decile 7. That means education and occupation are closer to average, but household economic resources rank much higher.

Transport to Work
Daily life is car-first: 91.2% of commuters drive, compared with only 1.7% using public transport and 1.0% walking or cycling. That works for households with cars, but it raises the cost of convenience for teenagers and non-drivers. Education is a practical strength, with 3 local schools spanning Government and Independent sectors and an ICSEA range from 980 to 1050. Mount Annan Christian College leads at 1050 and 1,059 enrolments, while Mount Annan Public School sits at 1005 with 653 enrolments. IRSAD decile 7 is above the middle, supporting a stable family setting.

It can suit investors seeking family tenants rather than high turnover. Renters are 19.8% of households, median rent is $480 a week, vacancy is 2.3%, and rent growth is 21.1%, but the renter pool is smaller than owner-occupier demand.

Is there much development in Mount Annan?
Yes. There were 36 development lodgements over 12 months, including secondary dwelling activity, sheds and alterations to existing homes. That points to incremental household expansion rather than a high-rise or apartment-led redevelopment cycle.
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.
