Brookfield is a smaller community of 3,640 — about 66% 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 $196,456/year runs 118% 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. Median rent of $400/week (~$1,733/month) covers only 62% of the median mortgage of $2,798/month — the remaining $1,065/month must be funded from other income, so this suburb tilts toward capital growth rather than yield. 12 km from Brisbane places Brookfield in the middle commuter belt, close enough for daily trips by car or rail but at a materially lower price point than inner suburbs.
Middle-ring locations like this one historically reward patient holders — focus on homes near catchment-zone schools and major transport. Local rents consume roughly 11% of household income — a useful sanity check on tenant affordability.

Strong buy-and-hold fundamentals: household incomes run 118% above the Queensland suburb median ($196,456 vs $90,298), and the 12 km CBD distance keeps this suburb in the primary demand zone. In Queensland, suburbs with this profile have historically clustered in the upper tercile of 10-year capital growth.
Weak cash flow: $400/week rent covers only 62% of the $2,798/month median mortgage — a $1,065/month gap that must be funded from other income. This suburb is a capital-growth play, not a yield play.
With 91% houses in a 3,640-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.

Brookfield scores 80/100 on our EquitySight investment framework — a good rating. That score is driven by a population of 3,640, median household income of $196,456/year and median weekly rent of $400. 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.
Brookfield has a usual resident population of approximately 3,640, compared with a Queensland suburb median of 5,474 — placing it in the lower half of the state's suburbs by size.

The median monthly mortgage repayment in Brookfield is $2,798, or approximately $33,576/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 $400 works out to $1,733/month, covering 62% of the median mortgage repayment of $2,798/month. That leaves a $1,065/month shortfall (around $12,780/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 (3,640 residents), interest-rate sensitivity on the $2,798 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.
