Coral Sea is a smaller community of 78 — about 1% of the Queensland suburb median (5,474) — so investors should factor in the narrower buyer pool and longer average time-on-market. Coral Sea's median household income of $71,448/year is 21% 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. The median weekly rent of $130 translates to approximately $6,760/year in gross rental income, setting the upper bound on yield before vacancy, rates, insurance and maintenance. Coral Sea is 1166 km from Brisbane, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.

Limited buy-and-hold upside: a small population of 78 means liquidity is thin and capital growth tends to lag the wider Queensland market over full cycles.
Gross rent of $130/week (~$6,760/year) sets the yield ceiling. Cross-check against your purchase price to confirm whether this suburb hits the 4–5% gross yield most Australian investors target.
With a population of 78, the resale market in Coral Sea may not reliably reward cosmetic renovations — a longer hold is typically a better strategy at this scale, letting land-value appreciation do the work instead.

The main risks are a thin buyer pool (78 residents), interest-rate sensitivity, below-median household incomes ($71,448 vs $90,298 state median), the broader Queensland market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
