South Bunbury's population of 8,810 sits 57% above the Western Australia suburb median of 5,605, giving it a wider tenant and buyer catchment than the average WA locality. South Bunbury's median household income of $74,776/year is 25% below the Western Australia suburb median ($99,736) — this is an affordability play where returns lean on yield and patient capital growth rather than demographic premium. Rent of $300/week (81% coverage of the $1,600/month median mortgage) leaves a gap of roughly $300/month that a typical investor bridges with negative gearing, depreciation and capital growth. South Bunbury is 157 km from Perth, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.
Regional property can deliver strong cash-flow yields but liquidity is tighter — plan for longer hold periods and verify local employment stability. Local rents consume roughly 21% of household income — a useful sanity check on tenant affordability.

Moderate rental coverage: rent of $300/week covers 81% of a $1,600/month mortgage, leaving a $300/month gap that an investor bridges with equity, depreciation and tax benefits.
Only 66% of dwellings are separate houses (vs 79% WA median) — this is a unit and townhouse market, where cosmetic flips struggle against body-corporate restrictions, thinner after-reno uplift and competing new supply.

That score is driven by a population of 8,810, median household income of $74,776/year and median weekly rent of $300. 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.

South Bunbury has a usual resident population of approximately 8,810, compared with a Western Australia suburb median of 5,605 — placing it in the upper half of the state's suburbs by size.

The most recent census recorded a median weekly rent of $300 in South Bunbury, equating to approximately $15,600/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 Bunbury is $1,600, or approximately $19,200/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 $300 works out to $1,300/month, covering 81% of the median mortgage repayment of $1,600/month. That leaves a $300/month shortfall (around $3,600/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 $1,600 median mortgage, below-median household incomes ($74,776 vs $99,736 state median), 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.
