Mount Byron is a smaller community of 21 — about 0% of the Queensland suburb median (5,474) — so investors should factor in the narrower buyer pool and longer average time-on-market. Mount Byron's median household income of $46,800/year is 48% 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 rent of $177/week (~$767/month) covers only 65% of the median mortgage of $1,171/month — the remaining $404/month must be funded from other income, so this suburb tilts toward capital growth rather than yield. At 50 km from Brisbane, Mount Byron is an outer-metro location where buyers are typically trading commute time for floor space and a lower entry price. Only 41% 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.

Mount Byron has a usual resident population of approximately 21, 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.
Mount Byron sits 50 km straight-line from the Brisbane CBD. This is an outer-metro location; local employment and infrastructure announcements tend to move prices more than CBD connectivity alone.
The most recent census recorded a median weekly rent of $177 in Mount Byron, equating to approximately $9,204/year in gross rental income (state median $385/week).

The median monthly mortgage repayment in Mount Byron is $1,171, or approximately $14,052/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 $177 works out to $767/month, covering 65% of the median mortgage repayment of $1,171/month. That leaves a $404/month shortfall (around $4,848/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 (21 residents), interest-rate sensitivity on the $1,171 median mortgage, below-median household incomes ($46,800 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.
