Socio-economic decile (IRSAD)
The ABS's advantage/disadvantage score, split into ten bands: 10 = most advantaged areas in the country, 1 = least.
Price impact: Wealthier catchments have deeper buyer pools, more owner-occupiers and lower forced-selling risk — that puts a floor under prices in downturns and speeds up recoveries. Rising IRSAD over time = gentrification in progress.
Favourable: Higher = stronger price floor
Renters vs owners
Renting households for every owner-occupier household. 0.5 means one renter household per two owner households.
Price impact: Owner-occupiers hold through downturns; heavy-investor areas see more synchronised selling when rates bite. Lower ratios generally mean stickier prices — but some renter-heavy areas are simply pre-gentrification.
Favourable: Below ~0.4 is owner-dominated
Units vs houses
How many units exist relative to houses in the area.
Price impact: Where units dominate, apartment oversupply can drag the whole market's stats. A low ratio means houses set the tone — and land, not buildings, drives long-run growth.
Years to own (affordability)
How long a local median-income family would need to fully pay off a typical home at current rates — over 30 means genuinely stretched.
Price impact: When locals can't afford local prices, growth has to come from richer buyers moving in. Affordable areas have more room to run when a growth cycle starts.
Favourable: Under ~35 years has headroom
School rank
Average quality of local schools, 1–100, built from NAPLAN and ACARA data.
Price impact: Catchment maps move markets. Families pay six-figure premiums to be inside good public-school catchments, and that demand is recession-resistant — parents don't un-enrol kids in a downturn.
Favourable: 70+ commands a premium
Public housing share
Share of homes that are government/social housing.
Price impact: High concentrations historically cap price growth and rental demand from private tenants. Watch for change: areas where governments are selling down stock have seen strong gentrification runs.
Favourable: Under ~3% typical for growth areas
Infrastructure spend per person
The dollar value of approved non-residential construction (roads, hospitals, schools, commercial) per adult, past 12 months.
Price impact: Cranes precede price growth. Big public and commercial investment brings jobs and amenity — the classic leading indicator that an area is being built into a better one.
Favourable: Higher = money flowing in
Economic diversity
How varied local employment is across industries, 0–100. One-industry towns score low.
Price impact: Diverse economies don't collapse when one employer sneezes. Low scores = your property's value is leveraged to a single industry's fortunes.
Favourable: 60+ is resilient
Mining/agriculture exposure
How dominant mining and agriculture are locally. Scored in reverse: 100 = barely any exposure, low scores = commodity town.
Price impact: Commodity-exposed markets move with iron ore and cattle prices, not property fundamentals — spectacular booms, brutal busts. Most burnt property investors in Australia bought mining-town 'bargains'.
Favourable: Higher = less boom-bust risk
Distance to CBD (GPO)
Kilometres to the nearest capital-city General Post Office — a standard proxy for 'how far from the CBD'.
Price impact: Scarcity of land near jobs is the engine of Australian capital growth. Every ring further out adds developable land — and supply is the enemy of growth.
