Kellyville
Twenty-seven thousand residents on 9.6 sqkm, a $3,122 weekly family income that lands in the 97.4th percentile nationally, and a population that has grown 904.7% over the past decade off a low Sydney Metro Northwest base: Kellyville is the textbook post-rail upgrade suburb of The Hills District. Detached houses make up 88.0% of dwellings and 78.8% have four or more bedrooms, anchoring an upmarket family identity that sits one tier below older established neighbour Castle Hill on overseas-born share (43.2% vs 45.4%) but matches it on SEIFA IRSAD decile 10. The migration mix skews local rather than international, with 804 net internal arrivals annually against 205 from overseas, marking it as a step-up destination for households leaving denser inner Sydney rather than a fresh migrant gateway.

Kellyville's median house price sits at $1.771M as of 2025, down 1.9% from the 2024 peak of $1.799M, making it cheaper than Baulkham Hills' $1.675M peer comp only on absolute dollars rather than per square metre given the larger 4-bedroom-plus stock here. With 78.8% of dwellings carrying four or more bedrooms and only 5.2% apartment share, the suburb is structurally aimed at families upgrading rather than first-home buyers, and the 54.0% mortgage-holder share confirms most owners are mid-cycle rather than outright. Mortgage repayments average $3,000 monthly against household income tracking near $13,000 monthly, producing a 22.8% mortgage-to-income ratio that stays below the 30% stress threshold, in contrast to Sydney's broader frontier-belt suburbs where ratios routinely top 30%.

For Investors
The renter share sits at 19.8%, well below the NSW state average near 32%, which constrains the lessor pool but lifts tenant quality given the 97.4th-percentile household income context. Median rent runs $630 weekly against the $1.771M house price, producing a gross yield around 1.85%, lower than Quakers Hill's roughly 3% yield and reflecting Kellyville's capital-growth-over-cashflow positioning. Vacancy sits at 4.0%, higher than the inner-Sydney sub-2% norm, hinting at higher rental supply in newer estates. Development activity is heavy with 143 lodgements in the past 12 months, mostly secondary dwellings and additions on detached blocks rather than apartment towers, and rent growth has run 55.8% over the past decade against 33.7% real income growth, signalling investor-favourable lease pricing power.

Demographics
The median age of 38 sits 2.0 years below the national figure, and 54.9% of adults hold a university qualification against the national 30% baseline, a 24.8 percentage-point gap that places Kellyville in elite educational company alongside Carlingford and Epping. Overseas-born share runs at 43.2%, 21.6 points higher than the national rate, with Chinese (3,706) and Indian (2,938) ancestries leading after the Other category and English. Household size averages 3.3 persons, 0.8 above the national average and consistent with the 78.8% four-bedroom-plus stock. Mandarin tops the language list at 980 home speakers, followed by Hindi at 479 and Cantonese at 377, mirroring the wider Hills District shift toward an Indian-Chinese family-investor mix that Castle Hill pioneered a decade earlier.

The 88.0% detached share and 78.8% four-or-more-bedroom share are the two structural numbers that define Kellyville's housing market, with semi-detached at 6.8% and apartments at just 5.2%, a near-inverse profile to inner-Sydney apartment-dominant suburbs like Maroubra. Tenure splits 26.2% owned outright, 54.0% mortgaged, and 19.8% rented, leaving the mortgaged-majority dynamic that tracks newer estates rather than legacy stock. The price-to-income ratio works out at roughly 11.2 times household income on a $1.771M median against $158K annual household earnings, lower than Mosman's 20-plus ratio but higher than Quakers Hill's near-9 ratio. Price action has cooled with a -1.9% CAGR over the latest year, against a longer-term rent rise of 55.8% reported across the past decade.

Economy & Employment
Healthcare leads at 15.1% of jobs, followed by Professional/Tech at 13.5%, Education at 10.7%, and Finance at 10.1%, an industry mix tilted toward white-collar service occupations rather than logistics or trades that dominate Western Sydney suburbs further out. Professionals (4,528) and Managers (2,622) together account for 57% of the working population, well above the national 38% average and consistent with the IEO score of 1106 in decile 9. The unemployment rate runs 4.5% against participation of 62.1%, and SEIFA disadvantage scores hit decile 10 across IRSD, IRSAD, and IER, marking Kellyville among the wealthiest 10% nationally on every income index. The 0.8 percentage-point gap between IEO decile 9 and IER decile 10 is small but typical of suburbs where high earnings outpace the spread of postgraduate qualifications.

William Clarke College anchors the school stack with an ICSEA score of 1162 across 1,951 students from kindergarten through Year 12, putting it ahead of Kellyville Public School at 1136 and Kellyville High School at 1086, with three additional Catholic and government primaries running ICSEA scores between 1105 and 1116. All six schools sit comfortably above the national ICSEA mean of 1000, a stronger uniform stack than most Hills peers can show. Public transport mode share runs at just 4.7% against 88.1% car-driver share, a high car-dependence figure despite the 2019 Sydney Metro Northwest opening, because the line skirts rather than penetrates the suburb's residential core. Volunteering at 13.8% sits near the national average, and the household composition skews family-heavy with 12,692 couples-with-children households dominating the 24,996-family total.

Population Forecast
+5.85%/yr
(+1,308 people/yr)
High GrowthPopulation is forecast to grow 5.85% annually, adding around 1,308 residents per year across 2026-2031 toward a medium projection of 29,363 by 2031, more than double the typical Sydney suburb growth rate of 1-2%. The driver mix is dominated by internal migration at 804 net annual arrivals against 205 net overseas, the inverse of inner-east migration patterns where overseas dominates. The 10-year retrospective shows 904.7% population growth, a mathematical artefact of the post-rail buildout from a low base, but the trajectory is now classified as Rejuvenating rather than greenfield. Real incomes have risen 33.7% over the decade and the young-adult share has climbed 3.2 percentage points while the senior share has fallen 2.5 points, confirming the suburb is replenishing rather than aging.

Frequently Asked Questions
Is Kellyville a good suburb to live in?
Kellyville suits families with school-age children and dual-income white-collar households, sitting in SEIFA decile 10 across all four indexes and posting a 97.4th-percentile household income nationally. The structural caveat is the 88.1% car-driver mode share and only 4.7% public transport use, meaning households without two cars will find the suburb inconvenient compared to denser train-corridor suburbs like Carlingford or Epping where Metro coverage is closer to home.
What is the median house price in Kellyville?
The median house price sits at $1.771M as of the 2025 quarter, down 1.9% from $1.799M in 2024 according to the NSW PSI-derived dataset. That places Kellyville above Quakers Hill's roughly $1.1M median and below Castle Hill's $2.2M-plus median, fitting its position as the mid-tier of the Hills District price ladder. Median rent is $630 weekly, producing a gross yield around 1.85%.
What schools are in Kellyville?
Six schools serve the suburb: William Clarke College (Combined, ICSEA 1162, 1,951 students, Independent), Kellyville Public School (ICSEA 1136, 855 students), Our Lady of The Rosary Primary (ICSEA 1116), Sherwood Ridge Public (ICSEA 1114), Our Lady of the Angels Primary (ICSEA 1105), and Kellyville High School (ICSEA 1086, 869 students). Every school exceeds the national ICSEA average of 1000, with William Clarke College sitting in the top decile nationally.
Is Kellyville safe?
Suburb-level NSW BOCSAR crime rates are not currently surfaced in this profile, but the SEIFA IRSAD decile of 10 and IRSD decile of 10 are strong proxies for low socio-economic disadvantage, and these scores typically correlate with crime rates 30-50% below the state median in Hills District suburbs. The suburb's 88.0% detached-house share and 22.9% turnover rate also point to a settled residential context rather than transient density.
Is Kellyville good for property investment?
Investment depends on strategy. The gross rental yield around 1.85% on a $630 weekly rent against the $1.771M median is below Western Sydney yields of 3-4%, so cashflow investors should look elsewhere. For capital-growth investors, the 5.85% annual population forecast, 143 development applications in the past 12 months, and 55.8% rent growth over the past decade signal sustained demand pressure on a constrained low-density base of 2,814 persons per sqkm.
How is Kellyville's population changing?
Population has grown from 20,274 in 2023 to 22,370 in 2025, and forecasts project 29,363 residents by 2031 under the medium scenario, an annual rate of 5.85% or roughly 1,308 new residents per year. The driver is 804 net internal migrants annually against 205 from overseas, with the young-adult share rising 3.2 percentage points and seniors falling 2.5 points, a Rejuvenating trajectory rather than greenfield.
What languages are spoken in Kellyville?
Kellyville is 43.2% overseas-born, 21.6 percentage points above the national rate, with Mandarin leading non-English languages at 980 home speakers, followed by Hindi (479), Cantonese (377), Arabic (316) and Korean (285). The Chinese ancestry count of 3,706 and Indian count of 2,938 reflects the Hills District's tilt toward South and East Asian family-investor migrants, a pattern Castle Hill established earlier and Kellyville now mirrors at slightly lower density.
What development is happening in Kellyville?
There were 143 development applications lodged across the past 12 months, dominated by detached dwelling construction, secondary dwellings (granny flats), and alterations and additions on existing residential blocks. The dwelling-house and CDC-pathway split favours small-scale residential rather than apartment towers, consistent with the 88.0% detached share and the 5.2% apartment ceiling. Vacancy at 4.0% is higher than the Sydney 2% benchmark, suggesting recent supply is meeting demand.
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.
