South Yilgarn is a smaller community of 15 — about 0% of the Western Australia suburb median (5,605) — so investors should factor in the narrower buyer pool and longer average time-on-market. Median household income of $117,000/year runs 17% above the Western Australia suburb median of $99,736, indicating strong purchasing power and the type of demographic profile that tends to sustain premium property prices through market cycles. South Yilgarn is 325 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.
