4,959 residents places Dundas squarely in the middle of the New South Wales suburb size distribution (state median 5,325), with market depth comparable to most NSW localities. Households here earn $102,024/year on average — 5% above the NSW suburb median of $97,552 — a modest premium that supports resilient owner-occupier demand. Rent of $428/week (74% coverage of the $2,500/month median mortgage) leaves a gap of roughly $645/month that a typical investor bridges with negative gearing, depreciation and capital growth. 17 km from Sydney places Dundas in the middle commuter belt, close enough for daily trips by car or rail but at a materially lower price point than inner suburbs. Only 49% of dwellings are separate houses (vs 76% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.
This suburb suits long-term investors looking for a balance of rental yield and capital growth. Schools and transport underpin family demand. Local rents consume roughly 22% of household income — a useful sanity check on tenant affordability.

Together these shape both owner-occupier and tenant demand and are the factors we weight most heavily in the suburb's investment score.
Dundas has a usual resident population of approximately 4,959, compared with a New South Wales suburb median of 5,325 — placing it in the lower half of the state's suburbs by size.

The most recent census recorded a median weekly rent of $428 in Dundas, equating to approximately $22,256/year in gross rental income (state median $430/week).

The median monthly mortgage repayment in Dundas is $2,500, or approximately $30,000/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 $428 works out to $1,855/month, covering 74% of the median mortgage repayment of $2,500/month. That leaves a $645/month shortfall (around $7,740/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 (4,959 residents), interest-rate sensitivity on the $2,500 median mortgage, 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.
