Dudley Park is a smaller community of 670 — about 18% of the South Australia suburb median (3,699) — so investors should factor in the narrower buyer pool and longer average time-on-market. Dudley Park's median household income of $47,164/year is 42% below the South Australia suburb median ($80,964) — this is an affordability play where returns lean on yield and patient capital growth rather than demographic premium. Median rent of $200/week (~$867/month) covers only 55% of the median mortgage of $1,575/month — the remaining $708/month must be funded from other income, so this suburb tilts toward capital growth rather than yield. At 6 km from the Adelaide CBD, Dudley Park sits inside the high-demand inner ring — properties here compete directly with the city's employment, transport and amenity networks.

Limited buy-and-hold upside: a small population of 670 means liquidity is thin and capital growth tends to lag the wider South Australia market over full cycles.
Weak cash flow: $200/week rent covers only 55% of the $1,575/month median mortgage — a $708/month gap that must be funded from other income. This suburb is a capital-growth play, not a yield play.
Only 62% of dwellings are separate houses (vs 73% SA median) — this is a unit and townhouse market, where cosmetic flips struggle against body-corporate restrictions, thinner after-reno uplift and competing new supply.

That score is driven by a population of 670, median household income of $47,164/year and median weekly rent of $200.

The main demand drivers in Dudley Park are proximity to Adelaide (6 km), a median household income of $47,164/year, a dwelling mix that is 62% separate houses, roughly 1 schools and 1 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.
Dudley Park has a usual resident population of approximately 670, compared with a South Australia suburb median of 3,699 — 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.
Dudley Park sits 6 km straight-line from the Adelaide CBD. This is inner-ring territory — pricing competes directly with established Adelaide employment nodes.
The most recent census recorded a median weekly rent of $200 in Dudley Park, equating to approximately $10,400/year in gross rental income (state median $320/week). Market rents have typically drifted above the recorded figure — verify against current listings on realestate.com.au and Domain before making an offer.
The median monthly mortgage repayment in Dudley Park is $1,575, or approximately $18,900/year (vs $1,616/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 $200 works out to $867/month, covering 55% of the median mortgage repayment of $1,575/month. That leaves a $708/month shortfall (around $8,496/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 (670 residents), interest-rate sensitivity on the $1,575 median mortgage, below-median household incomes ($47,164 vs $80,964 state median), the broader South Australia market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
