Plumpton
Filipino ancestry at 2,298 residents makes up the single largest identified ethnic group in Plumpton, ahead of English (1,140) and Indian (1,095), giving the suburb a distinctly non-Anglo cultural centre of gravity. With 53.4% born overseas, 31.8 points above the national baseline, and household size of 3.5 (1.0 above national), Plumpton is a migrant-majority, family-dense outer suburb. The $930,000 median house price sits below the Sydney median, yet mortgage holders at 52.1% dominate, the highest mortgage share in this cohort, creating a classic mortgage-belt profile. SEIFA IRSAD decile 5 places it at the national median on advantage, while IER decile 7 (above-average economic resources) outpaces IEO decile 4 (below-average education), an inversion where household wealth exceeds formal qualifications because multiple earners pool income.

The $930,000 median house price rose 9.1% from $880,000 in 2024 to $960,000 in 2025. Detached houses at 82.4% dominate overwhelmingly, with semi-detached at 16.9% and apartments nearly absent at 0.8%. Four-plus bedroom homes account for 48.7% and three-bedroom 44.2%, together making up 92.9% of stock, the most family-oriented housing mix in this cohort. The 2.6% vacancy rate is the tightest in this analysis group, confirming genuine supply scarcity. Mortgage holders at 52.1% form the clear majority, with outright owners at 20.8% and renters at 27.1%. Monthly mortgage repayments of $2,167 produce a mortgage-to-income ratio of 23.1%, below the stress threshold, partly because the 3.5 average household size means multiple earners contribute to servicing the mortgage. Couples with children at 4,352 families far outnumber couples without (1,138).

For Investors
Renters make up 27.1% of households, with median weekly rent of $430 against the $930,000 median producing a gross yield around 2.4%, above most Sydney suburbs in this cohort. The 2.6% vacancy rate is extremely tight, the lowest in this analysis group, indicating strong rental demand. The 46 development applications in 12 months include new dwellings and group homes, adding moderate new supply. Rent growth is not available over the decade, but the tight vacancy suggests upward rental pressure. Net overseas migration averages 200 per year, while internal migration shows a net outflow of 140 per year. Islam (1,793), Hinduism (914) and Christianity (5,474) point to diverse migrant communities that form stable tenant pools. Machinery/Drivers (667) and Labourers (533) among the top occupations suggest shift workers who value the proximity to western Sydney industrial corridors.

Demographics
Filipino (2,298), English (1,140) and Indian (1,095) ancestries lead, an unusual profile for Sydney where English typically dominates. Urdu (332), Hindi (324), Arabic (154), Punjabi (103) and Bengali (99) lead non-English languages, pointing to South Asian and Middle Eastern communities. With 53.4% born overseas, 31.8 points above the national baseline, Plumpton sits firmly in migrant-majority territory. The 42.7% university qualification rate sits 12.6 points above the national average, though the IEO decile 4 indicates education has not translated into higher-status occupations. Median age of 34 is 6 years below the national figure. Average household size of 3.5 is the highest in this cohort, 1.0 above national, driven by multigenerational households. Islam (1,793) and Hinduism (914) together nearly match Christianity (5,474). The 8.3% volunteering rate is among the lowest in this group.

Mortgage holders dominate at 52.1%, well above the national average, with outright owners at 20.8% and renters at 27.1%. This mortgage-heavy structure is the defining tenure feature of a young, family-dense outer suburb. Detached houses at 82.4% and four-plus bedrooms at 48.7% define the stock. Three-bedroom homes at 44.2% provide the remaining family options. Apartments are nearly absent at 0.8%. Prices rose from $880,000 to $960,000 (9.1%) in one year. Rent-to-income at 19.8% and mortgage-to-income at 23.1% both sit well below stress thresholds. The low stress ratios are partly explained by the high household size of 3.5, where multiple earners share costs. Only 12.7% of families are couples without children, the lowest childless-couple rate in this cohort, confirming that the housing fabric serves large, growing families.

Economy & Employment
Healthcare leads at 22.1%, followed by Manufacturing at 9.7%, Transport at 9.5%, Retail at 8.2% and Professional/Tech at 7.0%. The Manufacturing and Transport shares are notably higher than most suburbs, reflecting western Sydney's industrial corridor employment. The occupation profile is distinctly blue-collar: while Professionals lead at 822, Clerical/Admin (719), Machinery/Drivers (667), Labourers (533) and Community/Personal (491) follow closely. The SEIFA IER decile 7 exceeds the IEO decile 4 by 3 points, an inversion typical of migrant mortgage-belt suburbs where trade workers and operators earn solid wages without university qualifications. IRSAD decile 5 places Plumpton at the national median. The 6.5% unemployment rate is above the national average, and the 53.5% participation rate is below average, likely reflecting household structures where one partner does not work.

Western Grammar School (independent combined, ICSEA 1,073, 387 students) leads, followed by Good Shepherd Primary (Catholic, ICSEA 1,039, 626 students).

The gap between the independent/Catholic schools (above 1,000) and government schools (below 1,000) is consistent with the IEO decile 4 reading. No crime data is available. IRSD decile 4 (slightly above-average disadvantage) suggests moderate crime outcomes.

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.
