Gables
A household income sitting in the 98.2nd percentile nationally is the defining fact about Gables, a new release suburb in Sydney's north-west corridor with a median age of just 32, eight years below the national figure. Some 93% of dwellings have four or more bedrooms, the highest concentration of large-format family housing you will find anywhere in Greater Sydney. The population of 3,339 is young, highly educated (52.5% hold university qualifications, 22.4 points above national), and overwhelmingly owner-occupier: 71.5% carry a mortgage, compared to a national average closer to 35%.

The median house price in Gables is $1,020,000, a slight correction from $1,037,500 in 2024, a movement of negative 1.7% over one year. At that price, monthly mortgage repayments average $3,200, producing a mortgage-to-income ratio of 23.0%, below the 30% stress threshold, which is manageable relative to the 98.2nd-percentile household income. The stock is almost entirely separate houses at 96.5%, with apartments making up just 0.8%. Four-plus bedroom homes dominate at 93%, signalling a suburb built for families rather than downsizers. Only 9.1% of residents own outright, reflecting how recently the estate was developed and how many buyers are in the early stages of their mortgage.

Only 9.1% of residents own outright, reflecting how recently the estate was developed and how many buyers are in the early stages of their mortgage.
For Investors
Gables carries a vacancy rate of 4.6%, higher than the typical 2-3% equilibrium, which limits near-term yield upside. Weekly rent sits at $600 against a $1,020,000 median, implying a gross yield around 3.1%. Renters account for 19.5% of households, lower than the national average, so demand is there but not deep. The real case for investors is development momentum: 325 development applications were lodged in the past 12 months, one of the highest volumes in the north-west corridor, covering new dwellings, multi-dwelling terraces, and residential modifications. Population is young at median age 32, with large households averaging 3.4 people, both drivers of sustained housing demand as the suburb continues to fill out.

Gables is one of the most mortgage-dependent suburbs in NSW: 71.5% of residents carry a mortgage, compared to a national figure closer to 35%, because the estate is barely a decade old and nearly all buyers are in the accumulation phase. Outright owners make up just 9.1%. Separate houses constitute 96.5% of stock, with semi-detached at 2.6% and apartments at 0.8%. Four-plus bedroom homes account for 93% of dwellings, reflecting a suburb built exclusively for large families. The median house price moved from $1,037,500 in 2024 to $1,020,000 in 2025, a 1.7% fall over one year. Rent-to-income sits at 18.6%, comfortably below the 30% stress threshold, and mortgage-to-income at 23.0% also remains below stress levels despite the high median price.

Transport to Work
Car dependence is almost total in Gables: 90.4% of residents commute by car, versus the national average, and only 3.7% use public transport, which reflects the suburb's location within a still-developing north-west corridor where bus and rail access is limited. Walking and cycling account for just 0.9% of trips. No schools are recorded within the Gables boundary in this dataset, so families rely on facilities in neighbouring suburbs. The need-for-assistance rate is just 1.8% (59 people), consistent with a young, healthy population at median age 32. Volunteering runs at 10.9%. Housing stress is low: rent-to-income at 18.6% and mortgage-to-income at 23.0% both sit below the 30% threshold, a notable outcome for a suburb with a $1,020,000 median given the above-average incomes.

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.
