With 13,614 residents, Doonside is one of New South Wales's more populous suburbs — roughly 2.6× the state median of 5,325 — giving it a deep buyer and tenant pool that typically supports higher transaction volumes and shorter average days on market. Household income of $82,264/year is 16% below the New South Wales median of $97,552, typically translating into lower entry prices and a tenant base more sensitive to rent increases. Rent of $350/week (72% coverage of the $2,100/month median mortgage) leaves a gap of roughly $583/month that a typical investor bridges with negative gearing, depreciation and capital growth. At 33 km from Sydney, Doonside is an outer-metro location where buyers are typically trading commute time for floor space and a lower entry price.
This suburb suits yield-focused investors who are comfortable with lower liquidity. Employment concentration and local population trends matter more here than in metro markets. Local rents consume roughly 22% of household income — a useful sanity check on tenant affordability.

That score is driven by a population of 13,614, median household income of $82,264/year and median weekly rent of $350. 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 Doonside are a median household income of $82,264/year, a dwelling mix that is 85% separate houses, roughly 3 schools and 5 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.
Doonside has a usual resident population of approximately 13,614, compared with a New South Wales suburb median of 5,325 — placing it in the upper 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.
Doonside sits 33 km straight-line from the Sydney 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 $350 in Doonside, equating to approximately $18,200/year in gross rental income (state median $430/week).

The median monthly mortgage repayment in Doonside is $2,100, or approximately $25,200/year (vs $2,167/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 $350 works out to $1,517/month, covering 72% of the median mortgage repayment of $2,100/month. That leaves a $583/month shortfall (around $6,996/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 $2,100 median mortgage, below-median household incomes ($82,264 vs $97,552 state median), the broader New South Wales market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
