Cullinane is a smaller community of 551 — about 10% of the Queensland suburb median (5,474) — so investors should factor in the narrower buyer pool and longer average time-on-market. Cullinane's median household income of $64,168/year is 29% 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. Rent of $250/week (83% coverage of the $1,300/month median mortgage) leaves a gap of roughly $217/month that a typical investor bridges with negative gearing, depreciation and capital growth. Cullinane is 1320 km from Brisbane, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.

Cullinane scores 27/100 on our EquitySight investment framework — a weak rating. That score is driven by a population of 551, median household income of $64,168/year and median weekly rent of $250. 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.
The main demand drivers in Cullinane are a median household income of $64,168/year, a dwelling mix that is 74% separate houses, roughly 1 schools and 1 parks within the catchment. Together these shape both owner-occupier and tenant demand and are the factors we weight most heavily in the suburb's investment score.
Cullinane has a usual resident population of approximately 551, 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.
Cullinane sits 1320 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 $250 in Cullinane, equating to approximately $13,000/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 Cullinane is $1,300, or approximately $15,600/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 $250 works out to $1,083/month, covering 83% of the median mortgage repayment of $1,300/month. That leaves a $217/month shortfall (around $2,604/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 (551 residents), interest-rate sensitivity on the $1,300 median mortgage, below-median household incomes ($64,168 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.
