For Investors
Rental conditions are supported by a 41.5% renting share, weekly rent of $390 and a 6.6% vacancy rate. Rent growth of 14.5% indicates stronger recent movement than a flat-income market, while overseas migration is the primary forecast growth driver and may broaden tenant demand. Development activity is material, with 42 applications in the past 12 months. Recent examples include design and siting referrals, with one example stating 1 dwelling. A Stable forecast trajectory makes Alderley less speculative than a rapidly changing precinct, but gross yield cannot be judged without a verified purchase price. Compare apartments, semi-detached homes and separate houses separately because their 28.5%, 14.2% and 57.4% shares point to different tenant profiles.

The IRSAD decile is 9 and volunteering is 19.1%, placing socioeconomic advantage above the national midpoint and indicating some local participation. Need for assistance is 3.5%, or 228 people.

Population Forecast

(+100 people/yr)
EstablishedAlderley has an established outlook, with annual growth forecast at 1.38% and a Stable trajectory. Overseas migration is the primary driver, while population change across the wider area is 16.1% over 10 years. Rent growth of 14.5% is higher than the 11.9% real-income growth measure, which can tighten renter budgets if housing costs continue moving faster than earnings. Gentrification remains at the Early signs stage, with a score of 23, while the shift measure records affordability improving from 39.7 in 2011 to 33.0 in 2021. Compared with a rapid redevelopment story, this points to gradual change because established housing and migration-led demand are building pressure without a sharp trajectory break.

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 education open registers (school locations), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
