Subiaco's population of 9,940 sits 77% above the Western Australia suburb median of 5,605, giving it a wider tenant and buyer catchment than the average WA locality. Median household income of $115,388/year runs 16% above the Western Australia suburb median of $99,736, indicating strong purchasing power and the type of demographic profile that tends to sustain premium property prices through market cycles. Rent of $438/week (76% coverage of the $2,498/month median mortgage) leaves a gap of roughly $600/month that a typical investor bridges with negative gearing, depreciation and capital growth. At 3 km from the Perth CBD, Subiaco sits inside the high-demand inner ring — properties here compete directly with the city's employment, transport and amenity networks. Only 34% of dwellings are separate houses (vs 79% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.
Inner-city investors should model strata costs and rate rises carefully, since gross yields here are often compressed by higher entry prices. Local rents consume roughly 20% of household income — a useful sanity check on tenant affordability.

Subiaco scores 87/100 on our EquitySight investment framework — a strong rating. That score is driven by a population of 9,940, median household income of $115,388/year and median weekly rent of $438. Whether it fits your portfolio depends on whether you are targeting cash flow, capital growth, or a value-add renovation — all three are scored with suburb-specific numbers elsewhere on this page.
The main demand drivers in Subiaco are proximity to Perth (3 km), an above-state-median household income of $115,388/year, a dwelling mix that is 34% separate houses, roughly 2 schools and 4 parks within the catchment. Together these shape both owner-occupier and tenant demand and are the factors we weight most heavily in the suburb's investment score.
Subiaco has a usual resident population of approximately 9,940, compared with a Western Australia suburb median of 5,605 — placing it in the upper half of the state's suburbs by size. Population is the clearest proxy for market depth: more residents mean more transactions and typically a shorter average days-on-market on resale.
Subiaco sits 3 km straight-line from the Perth CBD. This is inner-ring territory — pricing competes directly with established Perth employment nodes.
The most recent census recorded a median weekly rent of $438 in Subiaco, equating to approximately $22,776/year in gross rental income (state median $350/week).

The median monthly mortgage repayment in Subiaco is $2,498, or approximately $29,976/year (vs $1,902/month state median). Stress-test your own borrowing at rates 1–2 percentage points above today's to make sure you can still service the loan through an RBA tightening cycle.
A median weekly rent of $438 works out to $1,898/month, covering 76% of the median mortgage repayment of $2,498/month. That leaves a $600/month shortfall (around $7,200/year before tax benefits), so a typical owner-occupier-priced property here is negatively geared. Actual cash flow depends on your deposit, loan terms, ownership costs and marginal tax rate — run the full numbers in our rental yield calculator.
The main risks are interest-rate sensitivity on the $2,498 median mortgage, a unit-heavy dwelling mix (34% houses) where body-corporate costs and apartment supply affect resale, the broader Western Australia market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
