Miller
At decile 1 on all four SEIFA indexes, Miller ranks in the bottom tenth nationally for both advantage and economic resources, yet house prices reached $910,000 in 2024-2025, a figure that sits uncomfortably above what local incomes support. Household income falls in just the 5.1st percentile nationally, and the mortgage-to-income ratio runs at 50.4%, well above the 30% stress threshold. Three in every five homes are renter-occupied, at 66.4%, double the national rate. With 39.3% of residents born overseas, the suburb is 17.7 percentage points above the national figure, and population has grown 82.2% over the past decade.

2024-2025 (PSI derived)
The median house price of $910,000 is a steep entry point given that household income sits in just the 5.1st percentile nationally. Prices rose 13.3% from $885,000 in 2024 to $1,003,000 at the 2025 peak. Monthly mortgage repayments average $1,800, producing a mortgage-to-income ratio of 50.4%, well above the 30% stress benchmark. Stock is predominantly separate houses at 68.0%, with apartments making up 27.6%. Three-bedroom homes dominate at 41.4% of dwellings, followed by 4-plus bedrooms at 26.8%. Only 15.6% of properties are owned outright and 18.0% are mortgaged, which means the buyer pool is thin relative to the renter majority, so entry-level demand for owner-occupiers is concentrated and competitive.

For Investors
A renter share of 66.4% gives landlords a wide and stable tenant pool, with weekly rent at $201 compared to the suburb's low income profile. The vacancy rate of 9.4% is elevated, which points to some oversupply in the rental stock. Development activity supports ongoing turnover, with 29 applications lodged in the past 12 months, including demolition-and-rebuild and secondary dwelling works. Population growth has been substantial, up 82.2% over the decade, with internal migration averaging 697 net arrivals annually as the primary driver. Annual price growth of 13.3% over the 2024-2025 period is strong, though yields are compressed given the gap between $201 weekly rent and a $910,000 median price.

Tenure
Tenure in Miller is dominated by renters at 66.4%, far higher than the national average, with mortgage holders at only 18.0% and outright owners at 15.6%. This tenure pattern is consistent with a decile 1 SEIFA profile where household incomes sit in the 5.1st percentile nationally. The median house price reached $1,003,000 at the 2025 peak, up 13.3% from $885,000 in 2024. Monthly mortgage repayments average $1,800, but the mortgage-to-income ratio of 50.4% indicates significant housing stress for those who do buy. Stock is predominantly separate houses (68.0%), with three-bedroom homes the most common at 41.4%. The vacancy rate of 9.4% is high relative to the Sydney average, suggesting some excess rental supply that may temper rent growth.

Economy & Employment
Healthcare dominates the local industry mix at 23.2% of workers, followed by Manufacturing (11.1%), Construction (8.5%), and Retail and Transport each at 7.2%. The top occupations are Machinery/Drivers (123 workers) and Labourers (112), reflecting a predominantly trade and manual workforce. The unemployment rate is 19.5%, substantially above the national average, and the participation rate of just 25.1% indicates that a large portion of the 3,374 residents are outside the labour force, with 1,550 not participating. Full-time employment accounts for 62.2% of those employed. Real income grew 16.6% over the decade, but from a very low base, and the household income remains in just the 5.1st percentile nationally. SEIFA decile 1 across all four indexes confirms this is one of the most economically disadvantaged suburbs in Australia.

Transport to Work
Car dependence is high at 82.5% of commuters driving, compared to only 5.4% using public transport, reflecting limited rail and bus access in this part of Liverpool. Walking and cycling account for 3.1% of journeys. No schools are recorded within the suburb boundary in this dataset. The IRSAD decile of 1 places Miller in the bottom tenth nationally for disadvantage, meaning a high share of residents face constrained access to services and resources. About 13.2% of residents, or 401 people, require daily assistance, above what is typical in middle-decile suburbs. Rent-to-income at 24.4% is within a manageable band, though mortgage-to-income at 50.4% is well above the 30% stress threshold. The volunteering rate is 5.4%, lower than national averages, consistent with a high workload and low-income community profile.

High GrowthMiller's population has grown 82.2% over the past decade, one of the highest rates in outer south-west Sydney, driven primarily by internal migration of 697 net arrivals annually. Overseas migration adds a further 46 net residents per year. The forecast trend is 3.56% annual growth, or roughly 709 additional persons each year. Medium projections put the broader SA2 area at around 19,594 by 2026, rising toward 23,141 by 2031. The gentrification stage is classified as Active with a score of 54, with rent growth of 55.6% over the period and real income growth of 16.6% indicating some displacement pressure. Affordability has worsened from 41.2% in 2011 to 44.6% in 2021, consistent with prices outpacing incomes in a decile 1 suburb under migration-driven 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.
