Dundas Valley
Almost half the residents of Dundas Valley were born overseas, 49.2%, which is 27.6 points above the national figure, and that migration story drives much of the suburb's character. Chinese ancestry leads at 1,614 residents ahead of English at 864 and Korean at 581, while Mandarin (431 speakers), Korean (270) and Cantonese (235) top the non-English languages. Household income sits in the 66.5th percentile nationally and SEIFA ranks the area decile 8 on IRSAD, an above-average advantage tier. The median house price of $1,727,500 and a young median age of 38, two years below national, complete a profile of an established, family-oriented pocket in Sydney's northwest.

The $1,727,500 median puts Dundas Valley firmly in Sydney's upper-middle bracket, and prices rose 4.0% from $1,683,500 in 2024 to $1,750,000 in 2025. The stock suits families: 65.4% are separate houses against only 4.7% apartments, and 41.0% of dwellings have four or more bedrooms with another 37.8% at three bedrooms. That scarcity of small stock means buyers seeking an entry-level unit have few options, because the suburb was built for owner-occupier households averaging 2.8 people, above the national average. Monthly mortgage repayments average $2,672, producing a mortgage-to-income ratio of 33.6%, above the 30% stress threshold despite incomes in the 66.5th percentile, so affordability is stretched for newer buyers.

For Investors
Renters make up 38.5% of households and weekly rent averages $428, giving landlords a solid tenant base in a house-dominated market where 65.4% of dwellings are separate houses. Against the $1,727,500 median that rent implies a gross yield near 1.3%, low by national standards, so the case rests on capital growth rather than income. Rent has grown 40.0% over the period, which is well above wage growth, and the 7.5% vacancy rate is moderate. Demand support is real: net overseas migration adds 323 residents a year, more than offsetting net internal outflow of 160. Development activity is steady at 60 applications in 12 months, skewed toward dual occupancy and secondary dwellings rather than apartment supply, which keeps the rental pool tight.

Demographics
The median age of 38 is 2.0 years below the national figure, a younger profile than the established-suburb label suggests, supported by an average household size of 2.8, which is 0.3 above national. Overseas-born residents reach 49.2%, fully 27.6 points above national, and ancestry is led by Chinese (1,614), then English (864) and Korean (581). The top non-English languages are Mandarin (431), Korean (270) and Cantonese (235), with Arabic (123) following. University qualifications stand at 49.6%, which is 19.5 points above national, reflecting a skilled migrant population. Christianity remains the largest religion at 2,824 residents, with Buddhism (251) and Islam (205) the notable next groups, consistent with the East Asian and Middle Eastern migration mix.

Tenure
Tenure is balanced across three groups: 37.9% carry a mortgage, 38.5% rent and 23.6% own outright. The high mortgage share relative to outright owners points to a younger, still-paying-down buyer base rather than long-held wealth. The stock is overwhelmingly detached at 65.4% separate houses and 29.9% semi-detached, leaving apartments at just 4.7%, so the housing market is built around families. Four-plus bedroom homes account for 41.0% and three-bedroom 37.8%, while one and two-bedroom dwellings together are only 21.3%. The median house price rose from $1,683,500 to $1,750,000 across 2024-2025, a 4.0% move. Mortgage-to-income at 33.6% sits above the stress threshold while rent-to-income at 23.3% stays comfortable, a divergence showing purchase prices are steep relative to local incomes in the 66.5th percentile.

Economy & Employment
The workforce concentrates in service and knowledge sectors: Healthcare leads at 15.5% (287 workers), Professional/Tech follows at 12.1% (223) and Education at 10.8% (200), with Construction at 9.8% and Retail at 6.5%. By occupation, Professionals (722) and Clerical/Admin (402) dominate, ahead of Managers (351), which aligns with the decile 8 IEO score for education and occupation. Unemployment runs at 5.9% and the full-time employment rate is 65.3%. Participation reads a low 49.3%, because 1,762 residents are not in the labour force, partly students and partly retirees. SEIFA shows an anomaly worth noting: IRSAD sits at decile 8 advantage but IRSD reads decile 5 for disadvantage and IER decile 6, because the 38.5% renter base and mixed migrant incomes pull aggregate resource measures below the education ranking.

Transport to Work
Dundas Valley is heavily car-dependent: 86.7% of commuters drive while only 4.6% use public transport and 1.8% walk or cycle, above the national reliance on cars, a function of its location away from the main rail line. The suburb scores decile 8 on IRSAD, an above-average advantage tier nationally, though the decile 5 IRSD reading shows a mixed disadvantage picture more typical of a migrant-gateway suburb. Volunteering runs at 13.2% and 5.4% of residents (299 people) need daily assistance. No schools are recorded inside the 1.81 km2 boundary in this dataset, so families rely on institutions in neighbouring suburbs, a practical trade-off offset by the spacious detached housing on lots that suit households averaging 2.8 people, above national.

(+182 people/yr)
EstablishedDundas Valley is classified as established but still expanding, with the surrounding catchment growing 17.4% over the past decade and trend forecasts pointing to roughly 0.93% annual growth, about 182 people a year. Overseas migration is the primary driver at a net 323 residents annually, while net internal migration runs at minus 160, so new arrivals from abroad more than replace those leaving for other parts of Sydney. The gentrification stage reads early signs with a score of 26 to 36, supported by an 18% population rise since 2011 and full recovery from a 3.2% COVID dip. Affordability worsened from 53.3% in 2011 to 55.4% in 2021, and rent growth of 40.0% over the period reflects rising demand pressure on a tight detached-house market.

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.
