Tregear
With all four SEIFA indexes sitting at decile 1, the lowest nationally, Tregear stands out as one of Greater Western Sydney's most economically stressed pockets. Yet the suburb has momentum: median house prices rose 11.4% from $745,000 in 2024 to $830,000 in 2025, and the population grew 38% over ten years. At 3,700 residents packed into 1.64 km2, it carries a density of 2,254 people per km2. The median age of 30 is 10 years below the national figure, anchoring a young, renter-majority community where 64.1% of households do not own their home.

Tregear's median house price of $780,000 sits below the broader Western Sydney average and rose 11.4% in the 2024 to 2025 period, from $745,000 to $830,000. The stock is 90.8% separate houses, giving buyers strong choice in detached dwellings, with 57.3% three-bedroom and 30.7% four-plus-bedroom homes available. Monthly mortgage repayments average $1,603, but the mortgage-to-income ratio reaches 33.6%, above the 30% stress threshold, because household income sits at only the 17.6th percentile nationally. Outright owners at 16.4% are well below national norms, pointing to a relatively recent wave of purchases among lower-income buyers. The gap between the 90.8% house share and the entry price makes Tregear one of the more accessible suburban markets for detached-house buyers in metro Sydney.
For Buyers
Tregear's median house price of $780,000 sits below the broader Western Sydney average and rose 11.4% in the 2024 to 2025 period, from $745,000 to $830,000. The stock is 90.8% separate houses, giving buyers strong choice in detached dwellings, with 57.3% three-bedroom and 30.7% four-plus-bedroom homes available. Monthly mortgage repayments average $1,603, but the mortgage-to-income ratio reaches 33.6%, above the 30% stress threshold, because household income sits at only the 17.6th percentile nationally. Outright owners at 16.4% are well below national norms, pointing to a relatively recent wave of purchases among lower-income buyers. The gap between the 90.8% house share and the entry price makes Tregear one of the more accessible suburban markets for detached-house buyers in metro Sydney.
For Investors
Rental demand is structural here: 64.1% of households rent, one of the highest renter shares in metro NSW, and weekly rent averages $300. Against the $780,000 median, that rent implies a gross yield around 2.0%, which is higher than many gentrifying inner suburbs. Vacancy sits at 9.7%, which is elevated compared to sub-3% metro norms, so investors should price in void periods. Development activity is steady at 22 applications in the past 12 months, including dual occupancy and secondary dwellings that signal continued densification. Overseas migration adds a net 183 residents a year to the SA2 area while internal migration removes 194 annually, meaning external demand is the growth driver. Rent grew 60% over the prior period, well above inflation, supporting the income case despite the high vacancy rate.

Demographics
The median age of 30 is 10 years below the national median, making Tregear one of Western Sydney's youngest suburbs. University qualifications reach only 11.2%, which is 18.9 percentage points below the national figure, reflecting the blue-collar and trade character of the workforce. Overseas-born residents account for 21.4%, in line with the national average. The dominant ancestry is English (1,006 residents), followed by Samoan (222), which is a notable community share compared to most NSW suburbs. Arabic (67 speakers) and Samoan (61) are the main non-English languages. Average household size is 2.8, above the national average of 2.5, consistent with the family-dense demographic. Couples with children (1,007 families) outnumber couples without children (393 families) by more than 2.5 to 1.

Tenure
Tenure is heavily renter-weighted: 64.1% rent, 19.5% hold mortgages and only 16.4% own outright, a tenure mix that is markedly different from the state average where outright ownership typically runs above 30%. The stock is almost entirely detached houses at 90.8%, with apartments at 6.7% and semi-detached at 2.6%. Three-bedroom homes dominate at 57.3%, with 30.7% having four or more bedrooms. The price moved from $745,000 in 2024 to $830,000 in 2025, an 11.4% gain over one year. Monthly mortgage costs of $1,603 represent 33.6% of median household income, above the conventional stress threshold of 30%, because household income at the 17.6th percentile nationally is below $1,200 per week. Rent-to-income at 27.2% is below the stress level, meaning renters face relatively less pressure than mortgagors.

Economy & Employment
Healthcare leads local employment at 18.6% of the employed workforce, followed by Transport at 11.7% and Construction at 9.0%, with Manufacturing and Retail each at 8.5%. By occupation, Machinery Operators and Drivers (234 workers) are the largest group, then Labourers (157) and Community and Personal Service workers (119), a pattern consistent with the decile 1 SEIFA IEO score for education and occupation. Unemployment is 14.6%, well above the national rate. The participation rate is only 33.5%, partly because 1,287 residents are not in the labour force. Real income grew 36.8% over the prior decade, which is positive, yet household income still sits at the 17.6th percentile nationally. Full-time employment among those working runs at 64.5%, which is broadly in line with national rates.

Transport to Work
Car dependency is very high: 84.8% of residents drive to work, well above the national average, while only 4.2% use public transport and 0.8% walk or cycle, reflecting limited active transport infrastructure. No schools are recorded inside the Tregear boundary in this dataset, so families rely on institutions in neighbouring 2770 postcode suburbs. Tregear ranks decile 1 on IRSAD, the bottom nationally for relative advantage, meaning residents face higher levels of disadvantage than 90% of Australian suburbs. The need-for-assistance rate is 10.0%, covering 327 residents who require daily help, which is above average compared to lower-disadvantage areas. Volunteering is at 6.9%, below most NSW benchmarks. Rent-to-income at 27.2% sits under the 30% stress line for the renter majority, providing some financial buffer for the 64.1% who do not own.

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.
