Coolum Beach's population of 9,152 sits 67% above the Queensland suburb median of 5,474, giving it a wider tenant and buyer catchment than the average QLD locality. Household income of $83,200/year is 8% below the Queensland median of $90,298, typically translating into lower entry prices and a tenant base more sensitive to rent increases. Median weekly rent of $450 equates to $1,950/month — about 98% of the median mortgage repayment of $2,000/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. Coolum Beach is 105 km from Brisbane, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Only 59% 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.
This suburb can suit investors targeting renter demand driven by lifestyle. Insurance, climate risk, and seasonal rental patterns all warrant a close look. Local rents consume roughly 28% of household income — a useful sanity check on tenant affordability.

The most recent census recorded a median weekly rent of $450 in Coolum Beach, equating to approximately $23,400/year in gross rental income (state median $385/week).

The median monthly mortgage repayment in Coolum Beach is $2,000, or approximately $24,000/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 $450 works out to $1,950/month, covering 98% of the median mortgage repayment of $2,000/month. That leaves a $50/month shortfall (around $600/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 interest-rate sensitivity on the $2,000 median mortgage, the broader Queensland market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
