Kooralgin is a smaller community of 47 — about 1% of the Queensland suburb median (5,474) — so investors should factor in the narrower buyer pool and longer average time-on-market. Kooralgin's median household income of $48,516/year is 46% below the Queensland suburb median ($90,298) — this is an affordability play where returns lean on yield and patient capital growth rather than demographic premium. Median weekly rent of $200 equates to $867/month — about 148% of the median mortgage repayment of $585/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. Kooralgin is 123 km from Brisbane, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Only 62% 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.
