Kenthurst
Two numbers define Kenthurst: a $3,185,000 median house price and a density of just 116.8 residents per km2, the second the cause of the first. The suburb spreads 5,313 people across 45.49 km2 of acreage, so 95.9% of dwellings are separate houses and 80.2% carry four or more bedrooms, the scarcity of subdividable land keeping prices in the ultra-luxury tier. Household income reaches the 97.5th percentile nationally, and SEIFA scores run decile 10 on both IER and IRSD. University qualifications at 38.4% sit 8.3 points above national, while the median age of 44 runs 4.0 years older, marking an established, settled population rather than a churning one.

At a $3,185,000 median, Kenthurst is a buyer's market only for the established and well capitalised, and the stock reinforces that. Separate houses make up 95.9% of dwellings and 80.2% have four or more bedrooms, with apartments at just 2.1%, so there is effectively no entry-level product. Prices moved modestly, from $3,150,000 in 2024 to $3,192,500 in 2025, a 1.3% rise that signals a mature, supply-constrained market rather than a hot one. Despite the price tag, average monthly mortgage repayments of $3,280 produce a mortgage-to-income ratio of 24.7%, comfortably below the 30% stress threshold, because household incomes sit in the 97.5th percentile. Owners who buy here tend to stay: 84.4% of residents remained at the same address, well above typical turnover.

For Investors
Kenthurst is a weak rental play and the numbers explain why. Only 10.0% of residents rent, the smallest tenant pool you will find in a premium market, and weekly rent of $550 against the $3,185,000 median implies a gross yield near 0.9%, far below holding costs. The 5.2% vacancy rate is healthy, but the thin 10.0% renter base means demand is shallow. Population growth of 0.62% a year, driven by net overseas migration of 176 against an internal outflow of 74, supports slow appreciation rather than yield. Development is modest at 74 applications in 12 months, mostly dwelling alterations and the occasional single new house rather than new supply. With rent growth of 37.5% over the period, the case rests on long-run capital growth, not cashflow.

Demographics
The median age of 44 runs 4.0 years above national, and the trajectory is aging: the senior share rose 5.1 points while the working-age share fell 3.1 points over the decade. Average household size is 3.3, which is 0.8 above national, reflecting the family profile, with 1,973 couples raising children against 1,087 couples with none. Overseas-born residents reach 20.5%, slightly below national by 1.1 points, an unusually Anglo-leaning mix for outer Sydney, led by English (1,798), Irish (534) and Italian (519) ancestry. University qualifications at 38.4% sit 8.3 points above the national figure. The most common non-English languages are Mandarin (59 speakers), Arabic (57) and Italian (51), small counts that confirm the established, locally rooted character.

Tenure
Tenure here is owner-dominated: 49.9% own their homes outright and 40.1% carry a mortgage, leaving renters at just 10.0%. That near-90% ownership rate, with outright owners outnumbering mortgage holders, points to long-held, debt-free wealth rather than recent buyer churn. The stock is overwhelmingly detached at 95.9%, with apartments and semi-detached dwellings at 2.1% each, and 80.2% of homes have four or more bedrooms against only 5.0% with two. The median house price rose from $3,150,000 in 2024 to $3,192,500 in 2025, a 1.3% one-year move. Mortgage-to-income sits at 24.7% and rent-to-income at 18.0%, both well below the 30% stress line, a comfort that reflects 97.5th-percentile household incomes carrying premium prices.

Economy & Employment
The workforce leans practical and entrepreneurial rather than purely corporate. Construction leads at 20.6% (380 workers), unusually high and consistent with an acreage suburb of tradespeople and self-employed builders, followed by Healthcare at 12.8% (236), Professional/Tech at 10.9% (201) and Education at 10.5% (193). By occupation, Managers (587) edge out Professionals (576), reflecting business owners as much as salaried staff. Unemployment is low at 3.6% and the full-time employment rate is 59.7%. Participation reads 56.1%, held down because the aging profile leaves 1,454 residents out of the labour force. SEIFA scores decile 10 on IER for economic resources and decile 8 on IEO for education and occupation, with real incomes up 13.1% over the decade.

Transport to Work
Kenthurst trades walkability for space, and the numbers show the bargain. Car dependence is near-total at 91.4% driving to work, with public transport at just 0.4% and active travel at 3.0%, the price of 116.8 residents per km2 across 45.49 km2 of low-density acreage. The payoff is room and quiet: 80.2% of homes have four or more bedrooms and households average 3.3 people. The suburb scores decile 10 on the IRSD index of relative disadvantage, the top tier, and only 3.7% of residents need daily assistance despite a median age of 44. Volunteering runs at 17.1%, consistent with a settled, community-minded population. No schools sit inside the 45.49 km2 boundary, so families drive to institutions in neighbouring suburbs, an accepted trade-off for the rural setting.

Population Forecast

(+142 people/yr)
EstablishedKenthurst is an established, slow-growth suburb: population rises 0.62% a year, about 142 people, and the 10-year change was a measured 11.1%. The only positive driver is net overseas migration of 176 a year, offset by an internal outflow of 74, so expansion depends on new arrivals rather than churn from within Sydney. The profile is aging, with the senior share up 5.1 points and the working-age share down 3.1 points over the decade, while the young-resident share slipped 1.8 points. Gentrification reads as early signs with a score of 32, modest for a suburb already in the 97.5th income percentile. Affordability held stable, easing only from 61.4% in 2011 to 60.7% in 2021, so the wealth base is entrenched rather than newly arrived.

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.
