The median house price of $1,537,500 reflects a premium inner-Sydney position, with prices rising 4.0% from $1,490,000 in 2024 to $1,550,000 in 2025. Separate houses are a minority at 22.5% of dwellings, compared to 39.1% apartments and 37.6% semi-detached, so buyers wanting detached stock face limited supply. Two-bedroom dwellings dominate at 45.8%, followed by three-bedroom at 28.9%, making two-bed the main entry point. Monthly mortgage repayments average $2,860, producing a mortgage-to-income ratio of 22.6%, below the 30% stress threshold, which is notable given the price level and reflects the suburb's high-income base at the 96.8th percentile nationally.

For Investors
Renters account for 46.2% of residents, well above the national average, providing a large and stable tenant pool. Weekly rent sits at $650, which against the $1,537,500 median implies a gross yield near 2.2%, typical for inner-Sydney. The vacancy rate of 9.3% is elevated and warrants attention, suggesting the apartment segment in particular faces absorption pressure. Development activity is active, with 41 applications lodged in the past 12 months, including complying development certificates and modifications to existing dwellings. The suburb's high income concentration and professional workforce compared to state averages support rental demand over the medium term.

Tenure
Tenure divides into 46.2% renting, 35.4% carrying a mortgage and 18.4% owning outright, a rental-heavy structure that reflects the young professional age profile and high property prices. Separate houses make up just 22.5% of stock compared to semi-detached at 37.6% and apartments at 39.1%, so the median house price of $1,537,500 is driven by scarce detached supply. Two-bedroom dwellings account for 45.8% of all dwellings, three-bedroom 28.9%, and 4-plus just 11.9%. Prices rose from $1,490,000 to $1,550,000 across 2024 to 2025, a 4.0% gain. Mortgage-to-income at 22.6% and rent-to-income at 22.2% both sit below stress thresholds, reflecting the suburb's above-average income base.

The household income at the 96.8th percentile nationally aligns with this high-skill concentration. The IRSAD score of 1,116 places the suburb in decile 10 nationally for advantage, while the IER sits at decile 6, reflecting a renter-heavy base that offsets individual income in wealth measures.

Transport to Work
Active and public transport use is high relative to most suburbs: 15.6% walk or cycle and 18.6% use public transport, while 61.0% drive, below typical car-dependent outer areas. The suburb scores decile 10 on IRSAD, the top advantage tier nationally, and decile 8 on IRSD, signalling very low relative disadvantage. Rent-to-income at 22.2% and mortgage-to-income at 22.6% both sit below stress levels, which means housing costs are not squeezing residents despite the $1,537,500 median. No schools are recorded inside the suburb boundary, so families rely on institutions in neighbouring areas. The suburb density of 2,098 residents per km2 reflects a compact urban form that supports walkability and the 15.6% walk or cycle share.

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.
