Kalgoorlie is a smaller community of 3,711 — about 66% of the Western Australia suburb median (5,605) — so investors should factor in the narrower buyer pool and longer average time-on-market. Households here earn $108,940/year on average — 9% above the WA suburb median of $99,736 — a modest premium that supports resilient owner-occupier demand. Rent of $300/week (86% coverage of the $1,517/month median mortgage) leaves a gap of roughly $217/month that a typical investor bridges with negative gearing, depreciation and capital growth. Kalgoorlie is 549 km from Perth, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Only 57% 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.
This suburb suits yield-focused investors who are comfortable with lower liquidity. Employment concentration and local population trends matter more here than in metro markets. Local rents consume roughly 14% of household income — a useful sanity check on tenant affordability.

Kalgoorlie has a usual resident population of approximately 3,711, 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 $300 in Kalgoorlie, equating to approximately $15,600/year in gross rental income (state median $350/week).

The median monthly mortgage repayment in Kalgoorlie is $1,517, or approximately $18,204/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 86% of the median mortgage repayment of $1,517/month. That leaves a $217/month shortfall (around $2,604/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 (3,711 residents), interest-rate sensitivity on the $1,517 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.
