Petrie's population of 8,722 sits 59% above the Queensland suburb median of 5,474, giving it a wider tenant and buyer catchment than the average QLD locality. Households here earn $96,356/year on average — 7% above the QLD suburb median of $90,298 — a modest premium that supports resilient owner-occupier demand. Median weekly rent of $360 equates to $1,560/month — about 90% of the median mortgage repayment of $1,725/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. 23 km from Brisbane places Petrie in the middle commuter belt, close enough for daily trips by car or rail but at a materially lower price point than inner suburbs.
Regional property can deliver strong cash-flow yields but liquidity is tighter — plan for longer hold periods and verify local employment stability. Local rents consume roughly 19% of household income — a useful sanity check on tenant affordability.

The main demand drivers in Petrie are proximity to Brisbane (23 km), an above-state-median household income of $96,356/year, a dwelling mix that is 82% separate houses, roughly 2 schools and 3 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.
Petrie has a usual resident population of approximately 8,722, compared with a Queensland suburb median of 5,474 — placing it in the upper half of the state's suburbs by size.

The median monthly mortgage repayment in Petrie is $1,725, or approximately $20,700/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 $360 works out to $1,560/month, covering 90% of the median mortgage repayment of $1,725/month. That leaves a $165/month shortfall (around $1,980/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 interest-rate sensitivity on the $1,725 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.
