Walliston is a smaller community of 1,016 — about 18% of the Western Australia suburb median (5,605) — so investors should factor in the narrower buyer pool and longer average time-on-market. At $98,124/year, household income in Walliston is within 2% of the Western Australia median ($99,736), placing the suburb firmly in the state's mainstream demographic band. Rent of $350/week (78% coverage of the $1,950/month median mortgage) leaves a gap of roughly $433/month that a typical investor bridges with negative gearing, depreciation and capital growth. 21 km from Perth places Walliston in the middle commuter belt, close enough for daily trips by car or rail but at a materially lower price point than inner suburbs.

Limited buy-and-hold upside: a small population of 1,016 means liquidity is thin and capital growth tends to lag the wider Western Australia market over full cycles.
Moderate rental coverage: rent of $350/week covers 78% of a $1,950/month mortgage, leaving a $433/month gap that an investor bridges with equity, depreciation and tax benefits.
With 91% houses in a 1,016-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.

That score is driven by a population of 1,016, median household income of $98,124/year and median weekly rent of $350. 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 Walliston are proximity to Perth (21 km), a median household income of $98,124/year, a dwelling mix that is 91% separate houses, roughly 1 schools and 1 parks within the catchment.

Walliston has a usual resident population of approximately 1,016, compared with a Western Australia suburb median of 5,605 — placing it in the lower 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.

The most recent census recorded a median weekly rent of $350 in Walliston, equating to approximately $18,200/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 Walliston is $1,950, or approximately $23,400/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 $350 works out to $1,517/month, covering 78% of the median mortgage repayment of $1,950/month. That leaves a $433/month shortfall (around $5,196/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 a thin buyer pool (1,016 residents), interest-rate sensitivity on the $1,950 median mortgage, 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.
