Sellicks Hill is a smaller community of 299 — about 8% 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 $93,184/year runs 15% 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. Median rent of $280/week (~$1,213/month) covers only 61% of the median mortgage of $2,000/month — the remaining $787/month must be funded from other income, so this suburb tilts toward capital growth rather than yield. At 46 km from Adelaide, Sellicks Hill is an outer-metro location where buyers are typically trading commute time for floor space and a lower entry price.

Limited buy-and-hold upside: a small population of 299 means liquidity is thin and capital growth tends to lag the wider South Australia market over full cycles.
Weak cash flow: $280/week rent covers only 61% of the $2,000/month median mortgage — a $787/month gap that must be funded from other income. This suburb is a capital-growth play, not a yield play.
With 87% houses in a 299-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 299, median household income of $93,184/year and median weekly rent of $280.

Sellicks Hill has a usual resident population of approximately 299, compared with a South Australia suburb median of 3,699 — placing it in the lower half of the state's suburbs by size.

Sellicks Hill sits 46 km straight-line from the Adelaide 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 $280 in Sellicks Hill, equating to approximately $14,560/year in gross rental income (state median $320/week).

The median monthly mortgage repayment in Sellicks Hill is $2,000, or approximately $24,000/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 $280 works out to $1,213/month, covering 61% of the median mortgage repayment of $2,000/month. That leaves a $787/month shortfall (around $9,444/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 (299 residents), interest-rate sensitivity on the $2,000 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.
