Eight Mile Creek is a smaller community of 163 — about 4% of the South Australia suburb median (3,699) — so investors should factor in the narrower buyer pool and longer average time-on-market. Households here earn $92,612/year on average — 14% above the SA suburb median of $80,964 — a modest premium that supports resilient owner-occupier demand. Median rent of $193/week (~$836/month) covers only 58% of the median mortgage of $1,436/month — the remaining $600/month must be funded from other income, so this suburb tilts toward capital growth rather than yield. Eight Mile Creek is 396 km from Adelaide, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.

Weak cash flow: $193/week rent covers only 58% of the $1,436/month median mortgage — a $600/month gap that must be funded from other income. This suburb is a capital-growth play, not a yield play.
Only 59% 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 163, median household income of $92,612/year and median weekly rent of $193.

Together these shape both owner-occupier and tenant demand and are the factors we weight most heavily in the suburb's investment score.
Eight Mile Creek has a usual resident population of approximately 163, 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.
Eight Mile Creek sits 396 km straight-line from the Adelaide CBD. This is a regional market where CBD distance is only indicative — local industry diversity and commute alternatives matter more.
The most recent census recorded a median weekly rent of $193 in Eight Mile Creek, equating to approximately $10,036/year in gross rental income (state median $320/week).

The median monthly mortgage repayment in Eight Mile Creek is $1,436, or approximately $17,232/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 $193 works out to $836/month, covering 58% of the median mortgage repayment of $1,436/month. That leaves a $600/month shortfall (around $7,200/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 (163 residents), interest-rate sensitivity on the $1,436 median mortgage, 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.
