Coochiemudlo Island is a smaller community of 850 — about 16% of the Queensland suburb median (5,474) — so investors should factor in the narrower buyer pool and longer average time-on-market. Coochiemudlo Island's median household income of $46,384/year is 49% 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 $293 equates to $1,270/month — about 99% of the median mortgage repayment of $1,289/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. At 32 km from Brisbane, Coochiemudlo Island is an outer-metro location where buyers are typically trading commute time for floor space and a lower entry price.

The median monthly mortgage repayment in Coochiemudlo Island is $1,289, or approximately $15,468/year (vs $1,733/month state median). Stress-test your own borrowing at rates 1–2 percentage points above today's to make sure you can still service the loan through an RBA tightening cycle.
A median weekly rent of $293 works out to $1,270/month, covering 99% of the median mortgage repayment of $1,289/month. That leaves a $19/month shortfall (around $228/year before tax benefits), so a typical owner-occupier-priced property here is negatively geared. Actual cash flow depends on your deposit, loan terms, ownership costs and marginal tax rate — run the full numbers in our rental yield calculator.
The main risks are a thin buyer pool (850 residents), interest-rate sensitivity on the $1,289 median mortgage, below-median household incomes ($46,384 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.
