Greenfield Park
Overseas-born residents make up 62.9% of Greenfield Park's 5,394 people, a share 41.3 percentage points above the national figure. At 1.5 sq km and 3,589.3 people per sq km, it is a compact suburb, while the median age of 38 is 2 years below national. Average household size is 3.5, one person above national, helping explain the 94.0% separate-house share and 49.8% four-plus-bedroom profile. Growth is slow at 0.38% annually and is shaped by overseas migration and an ageing trajectory. Compared with nearby St Johns Park and Prairiewood, Greenfield Park's defining combination is compact density, detached housing and overseas migration.

Buyers are entering a strongly detached market: 94.0% of dwellings are separate houses, while apartments and semi-detached homes each account for 3.0%. Family-sized stock dominates, with 49.8% of homes having four or more bedrooms and 41.1% having three. The $2,000 monthly mortgage figure sits alongside a 31.3% mortgage-to-income share, slightly higher than the 31.1% rent-to-income share, so borrowing capacity deserves close testing. Compared with unit-led areas, Greenfield Park suits buyers prioritising larger homes, but worsening affordability, moving from 84.2 in 2011 to 94.7 in 2021, raises the risk of budget pressure.

For Investors
Greenfield Park has a tenant base worth testing, with 30.1% of households renting, weekly rent at $460 and vacancy at 1.6%. Compared with a high-vacancy market, the 1.6% rate suggests tighter available rental stock, while rent growth of 36.4% is far higher than the 0.38% annual population trend. Overseas migration is the primary growth driver, which can broaden rental demand, and 36 development items in 12 months include secondary-dwelling and residential-accommodation work. Compared with a low-demand market, the local setting may support occupancy, but mortgage-to-income pressure at 31.3% warrants conservative cash-flow assumptions.

Economy & Employment
Employment is anchored by healthcare at 17.7% with 156 workers, education at 11.5% with 101, construction at 9.0% with 79, professional and technical work at 8.6% with 76, and manufacturing at 7.3% with 64. Occupations are similarly mixed, led by professionals at 292, clerical and administrative workers at 235, machinery and drivers at 207, trades at 203 and labourers at 186. Participation is 40.1%, full-time employment is 49.1% and unemployment is 8.8%, giving the suburb a lower participation profile than a highly workforce-intensive area. Household income ranks at the 45.8 percentile. SEIFA IEO is decile 3 and IER decile 4, while IRSD is decile 1 and IRSAD decile 2. The lower disadvantage deciles, compared with the slightly higher education and economic-resource deciles, point to constrained social conditions despite varied employment.

Transport to Work
Daily life is car-oriented: 61.7% travel as car drivers, compared with 1.9% using public transport and 0.6% walking or cycling. A further 30.7% work from home, which may reduce commuting but increases the value of local shops and services. The suburb packs 5,394 residents into 1.5 sq km, or 3,589.3 people per sq km, so convenience depends on short local trips and efficient road access. Families should check the exact address for school enrolment zones and travel times rather than assume suburb boundaries determine access. Social conditions need attention too: 10.1% need assistance, or 514 people, while IRSAD is decile 2 and IRSD decile 1, both below higher-decile areas. Compared with more transit-oriented suburbs, Greenfield Park is better suited to households comfortable with driving.

Frequently Asked Questions
Is Greenfield Park a good suburb to live in?
Greenfield Park can suit households seeking established detached housing, with 94.0% separate houses and 49.8% four-plus-bedroom homes. Its 61.7% car-driver share makes it more car-oriented than walking-oriented, where only 0.6% walk or cycle to work. The 1.5 sq km footprint is compact, so check transport, services and enrolment zones at the exact address.
What is the median house price in Greenfield Park?
A current median house price should be checked against recent sales rather than inferred from rent. Greenfield Park has a $460 weekly median rent and 94.0% separate houses, so detached-home pricing is the relevant comparison, not apartment pricing. Buyers should also test repayments against the 31.3% mortgage-to-income share.
What schools are in Greenfield Park?
School choices should be confirmed by exact address and enrolment zone, including public and independent options, because suburb boundaries do not determine every catchment. Greenfield Park covers 1.5 sq km and 61.7% of workers drive, so travel time can matter more than a school's suburb label. Check current catchments before buying or renting.
Is Greenfield Park safe?
Check current NSW Police and council updates for the exact streets before deciding. Greenfield Park has 87.9% of residents staying at the same address and 12.1% turnover, suggesting residential stability, but those figures are not a crime rating. Compare recent incidents, lighting, traffic and local activity before choosing a property.
Is Greenfield Park good for property investment?
Greenfield Park has some supportive rental fundamentals: 30.1% of households rent, weekly rent is $460 and vacancy is 1.6%. Rent growth of 36.4% is higher than the 0.38% annual population trend, while overseas migration is the primary growth driver. However, 31.3% mortgage-to-income pressure and 36 development items in 12 months call for conservative assumptions compared with a low-cost, low-vacancy market.
How is Greenfield Park's population changing?
Greenfield Park has 5,394 residents today, with annual growth running at 0.38%. Across the wider area, population change is 14.1% over ten years and overseas migration is the primary driver. The trajectory is Aging: senior share has increased 6.7 points, while young share has fallen 2.1 points. Compared with faster-growth suburbs, change is gradual and increasingly shaped by established households.
What languages are spoken in Greenfield Park?
Greenfield Park has a strong overseas-born profile at 62.9%, which is 41.3 percentage points above national. Arabic is recorded for 203 residents, Khmer for 68, Cantonese for 50, Mandarin for 45 and Italian for 40. Compared with the national mix, these figures point to substantial multilingual demand for accessible local services and communication.
What development is occurring in Greenfield Park?
There were 36 development items in the past 12 months, including secondary dwellings, residential accommodation and demolition work. That activity is consistent with an established suburb where homes are more likely to be altered or added to than replaced by large new estates. Compared with a greenfield release area, the 94.0% separate-house share and 0.38% annual growth suggest incremental change.
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 education open registers (school locations), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
