Port Gawler is a smaller community of 112 — about 3% 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 $109,200/year runs 35% 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 $235/week (~$1,018/month) covers only 61% of the median mortgage of $1,672/month — the remaining $654/month must be funded from other income, so this suburb tilts toward capital growth rather than yield. At 34 km from Adelaide, Port Gawler is an outer-metro location where buyers are typically trading commute time for floor space and a lower entry price. Separate houses make up 94% of dwellings — 21 percentage points above the South Australia median of 73% — pointing to a family-oriented, land-rich market where value is concentrated in the underlying block.

Weak cash flow: $235/week rent covers only 61% of the $1,672/month median mortgage — a $654/month gap that must be funded from other income. This suburb is a capital-growth play, not a yield play.
With 94% houses in a 112-person market, renovation margins depend on individual street and aspect rather than any suburb-wide story — do comparable-sales analysis before committing capital.

The most recent census recorded a median weekly rent of $235 in Port Gawler, equating to approximately $12,220/year in gross rental income (state median $320/week).

The median monthly mortgage repayment in Port Gawler is $1,672, or approximately $20,064/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 $235 works out to $1,018/month, covering 61% of the median mortgage repayment of $1,672/month. That leaves a $654/month shortfall (around $7,848/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 (112 residents), interest-rate sensitivity on the $1,672 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.
