St Agnes is a smaller community of 20 — about 0% of the Queensland suburb median (5,474) — so investors should factor in the narrower buyer pool and longer average time-on-market. St Agnes's median household income of $68,224/year is 24% 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.
