Diglum is a smaller community of 56 — about 1% of the Queensland suburb median (5,474) — so investors should factor in the narrower buyer pool and longer average time-on-market. Households here earn $95,316/year on average — 6% above the QLD suburb median of $90,298 — a modest premium that supports resilient owner-occupier demand. Weekly rent of $300 covers just 30% of the median $4,333/month mortgage repayment, leaving a $3,033/month gap — investors should only pursue this suburb with a clear capital-growth thesis and sufficient external income to fund the shortfall. Diglum is 407 km from Brisbane, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Only 60% 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.

Limited buy-and-hold upside: a small population of 56 means liquidity is thin and capital growth tends to lag the wider Queensland market over full cycles.
Weak cash flow: $300/week rent covers only 30% of the $4,333/month median mortgage — a $3,033/month gap that must be funded from other income. This suburb is a capital-growth play, not a yield play.
Only 60% of dwellings are separate houses (vs 77% QLD median) — this is a unit and townhouse market, where cosmetic flips struggle against body-corporate restrictions, thinner after-reno uplift and competing new supply.

Diglum scores 45/100 on our EquitySight investment framework — a moderate rating. That score is driven by a population of 56, median household income of $95,316/year and median weekly rent of $300. 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.
Diglum has a usual resident population of approximately 56, 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.
Diglum sits 407 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 $300 in Diglum, equating to approximately $15,600/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 Diglum is $4,333, or approximately $51,996/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 $300 works out to $1,300/month, covering 30% of the median mortgage repayment of $4,333/month. That leaves a $3,033/month shortfall (around $36,396/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 (56 residents), interest-rate sensitivity on the $4,333 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.
