Willow Creek is a smaller community of 48 — about 1% of the South Australia suburb median (3,699) — so investors should factor in the narrower buyer pool and longer average time-on-market. Median household income of $143,000/year runs 77% above the South Australia suburb median of $80,964, indicating strong purchasing power and the type of demographic profile that tends to sustain premium property prices through market cycles. Weekly rent of $207 covers just 43% of the median $2,100/month mortgage repayment, leaving a $1,203/month gap — investors should only pursue this suburb with a clear capital-growth thesis and sufficient external income to fund the shortfall. Willow Creek is 73 km from Adelaide, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.

Limited buy-and-hold upside: a small population of 48 means liquidity is thin and capital growth tends to lag the wider South Australia market over full cycles.
Weak cash flow: $207/week rent covers only 43% of the $2,100/month median mortgage — a $1,203/month gap that must be funded from other income. This suburb is a capital-growth play, not a yield play.
With 78% houses in a 48-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.

That score is driven by a population of 48, median household income of $143,000/year and median weekly rent of $207.

Willow Creek has a usual resident population of approximately 48, 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.
Willow Creek sits 73 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 $207 in Willow Creek, equating to approximately $10,764/year in gross rental income (state median $320/week).

The median monthly mortgage repayment in Willow Creek is $2,100, or approximately $25,200/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 $207 works out to $897/month, covering 43% of the median mortgage repayment of $2,100/month. That leaves a $1,203/month shortfall (around $14,436/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 (48 residents), interest-rate sensitivity on the $2,100 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.
