Kalkadoon is a smaller community of 27 — about 0% of the Queensland suburb median (5,474) — so investors should factor in the narrower buyer pool and longer average time-on-market. Median household income of $169,000/year runs 87% above the Queensland suburb median of $90,298, indicating strong purchasing power and the type of demographic profile that tends to sustain premium property prices through market cycles. Rent of $323/week (78% coverage of the $1,800/month median mortgage) leaves a gap of roughly $400/month that a typical investor bridges with negative gearing, depreciation and capital growth. Kalkadoon is 1567 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 27 means liquidity is thin and capital growth tends to lag the wider Queensland market over full cycles.
Moderate rental coverage: rent of $323/week covers 78% of a $1,800/month mortgage, leaving a $400/month gap that an investor bridges with equity, depreciation and tax benefits.
With 69% houses in a 27-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.

That score is driven by a population of 27, median household income of $169,000/year and median weekly rent of $323. Whether it fits your portfolio depends on whether you are targeting cash flow, capital growth, or a value-add renovation — all three are scored with suburb-specific numbers elsewhere on this page.

Together these shape both owner-occupier and tenant demand and are the factors we weight most heavily in the suburb's investment score.
Kalkadoon has a usual resident population of approximately 27, compared with a Queensland suburb median of 5,474 — placing it in the lower half of the state's suburbs by size. Population is the clearest proxy for market depth: more residents mean more transactions and typically a shorter average days-on-market on resale.
Kalkadoon sits 1567 km straight-line from the Brisbane CBD. This is a regional market where CBD distance is only indicative — local industry diversity and commute alternatives matter more.
The most recent census recorded a median weekly rent of $323 in Kalkadoon, equating to approximately $16,796/year in gross rental income (state median $385/week). Market rents have typically drifted above the recorded figure — verify against current listings on realestate.com.au and Domain before making an offer.
The median monthly mortgage repayment in Kalkadoon is $1,800, or approximately $21,600/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 $323 works out to $1,400/month, covering 78% of the median mortgage repayment of $1,800/month. That leaves a $400/month shortfall (around $4,800/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 (27 residents), interest-rate sensitivity on the $1,800 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.
