Salmon Gums is a smaller community of 146 — about 3% of the Western Australia suburb median (5,605) — so investors should factor in the narrower buyer pool and longer average time-on-market. Salmon Gums's median household income of $46,800/year is 53% 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. Median rent of $104/week (~$451/month) covers only 68% of the median mortgage of $661/month — the remaining $210/month must be funded from other income, so this suburb tilts toward capital growth rather than yield. Salmon Gums is 551 km from Perth, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.

Limited buy-and-hold upside: a small population of 146 means liquidity is thin and capital growth tends to lag the wider Western Australia market over full cycles.
Moderate rental coverage: rent of $104/week covers 68% of a $661/month mortgage, leaving a $210/month gap that an investor bridges with equity, depreciation and tax benefits.
With 76% houses in a 146-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.

Salmon Gums has a usual resident population of approximately 146, compared with a Western Australia suburb median of 5,605 — placing it in the lower half of the state's suburbs by size.

The most recent census recorded a median weekly rent of $104 in Salmon Gums, equating to approximately $5,408/year in gross rental income (state median $350/week).

The median monthly mortgage repayment in Salmon Gums is $661, or approximately $7,932/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 $104 works out to $451/month, covering 68% of the median mortgage repayment of $661/month. That leaves a $210/month shortfall (around $2,520/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 (146 residents), interest-rate sensitivity on the $661 median mortgage, below-median household incomes ($46,800 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.
