O'Briens Hill is a smaller community of 11 — about 0% of the Queensland suburb median (5,474) — so investors should factor in the narrower buyer pool and longer average time-on-market. Median household income of $117,000/year runs 30% above the Queensland suburb median of $90,298, indicating strong purchasing power and the type of demographic profile that tends to sustain premium property prices through market cycles. O'Briens Hill is 1322 km from Brisbane, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Only 38% of dwellings are separate houses (vs 77% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.
