With 12,596 residents, South Perth is one of Western Australia's more populous suburbs — roughly 2.2× the state median of 5,605 — giving it a deep buyer and tenant pool that typically supports higher transaction volumes and shorter average days on market. Households here earn $105,352/year on average — 6% above the WA suburb median of $99,736 — a modest premium that supports resilient owner-occupier demand. Rent of $375/week (74% coverage of the $2,200/month median mortgage) leaves a gap of roughly $575/month that a typical investor bridges with negative gearing, depreciation and capital growth. At 3 km from the Perth CBD, South Perth sits inside the high-demand inner ring — properties here compete directly with the city's employment, transport and amenity networks. Only 28% 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.
Outer-metro suburbs reward careful property selection — aim for homes near infrastructure rather than generic house-and-land packages. Local rents consume roughly 19% of household income — a useful sanity check on tenant affordability.

South Perth scores 75/100 on our EquitySight investment framework — a good rating. That score is driven by a population of 12,596, median household income of $105,352/year and median weekly rent of $375. 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 South Perth are proximity to Perth (3 km), an above-state-median household income of $105,352/year, a dwelling mix that is 28% separate houses, roughly 3 schools and 5 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.
South Perth has a usual resident population of approximately 12,596, 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.
South Perth 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 $375 in South Perth, equating to approximately $19,500/year in gross rental income (state median $350/week). Market rents have typically drifted above the recorded figure — verify against current listings on realestate.com.au and Domain before making an offer.
The median monthly mortgage repayment in South Perth is $2,200, or approximately $26,400/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 $375 works out to $1,625/month, covering 74% of the median mortgage repayment of $2,200/month. That leaves a $575/month shortfall (around $6,900/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 $2,200 median mortgage, a unit-heavy dwelling mix (28% 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.
