Australia's Highest-Rent Suburbs: The Affluence Score
Where do Australia's highest-paid tenants live? One of nine dimensions in the Microburbs livability score, validated against actual market outcomes for 4,127 Australian suburbs.
Luke Metcalfe · Microburbs Research · May 2026★ The headline finding
Affluent suburbs collect the highest rents in Australia: $580 per week in the top quartile vs $410 in the bottom — a 41% premium for the same dwelling.
What this means for you as an investor
For an income-focused investor, the affluence score points to suburbs where tenants have the highest disposable income, the most stable employment, and the longest payment histories. Top-quartile affluence suburbs collect $170 per week more in rent on the same kind of property than bottom-quartile suburbs — that is $8,840 extra per year, every year, on the same building.
Who this dimension is for
Long-term landlords who prioritise tenant quality, payment stability, and rental income over yield. Investors building a portfolio in suburbs where vacancies are uncommon and tenants stay multiple years.
A real example
Cottesloe (WA) — top 0.6% on affluence
Within Cottesloe (WA), every street is different
The affluence score is calculated for every individual microburb (street-block of 30 to 60 dwellings), not just the suburb average. The map below shows Cottesloe (WA) broken down by microburb. Some streets within Cottesloe (WA) score higher on affluence than others — the variation can be just as wide as the variation between suburbs.
Within Cottesloe (WA), the top-affluence microburbs are not necessarily on the same streets as the top-affluence or top-tranquility microburbs. The street you buy on still matters, even after you have chosen the right suburb. This is why the Microburbs score is calculated at street-block level, not just suburb level.
What this dimension measures
The affluence score combines: household income, occupational mix (managers and professionals), education levels, owner-occupation rates, the SEIFA socioeconomic advantage index, and work-from-home rates as a proxy for white-collar employment.
The honest trade-off
