Whyalla Stuart's population of 6,476 sits 75% above the South Australia suburb median of 3,699, giving it a wider tenant and buyer catchment than the average SA locality. Whyalla Stuart's median household income of $45,760/year is 43% 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. Rent of $160/week (72% coverage of the $967/month median mortgage) leaves a gap of roughly $274/month that a typical investor bridges with negative gearing, depreciation and capital growth. Whyalla Stuart is 233 km from Adelaide, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Only 30% of dwellings are separate houses (vs 73% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.
This suburb can suit investors targeting renter demand driven by lifestyle. Insurance, climate risk, and seasonal rental patterns all warrant a close look. Local rents consume roughly 18% of household income — a useful sanity check on tenant affordability.

That score is driven by a population of 6,476, median household income of $45,760/year and median weekly rent of $160.

Whyalla Stuart has a usual resident population of approximately 6,476, compared with a South Australia suburb median of 3,699 — placing it in the upper half of the state's suburbs by size.

The most recent census recorded a median weekly rent of $160 in Whyalla Stuart, equating to approximately $8,320/year in gross rental income (state median $320/week).

The median monthly mortgage repayment in Whyalla Stuart is $967, or approximately $11,604/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 $160 works out to $693/month, covering 72% of the median mortgage repayment of $967/month. That leaves a $274/month shortfall (around $3,288/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 interest-rate sensitivity on the $967 median mortgage, below-median household incomes ($45,760 vs $80,964 state median), a unit-heavy dwelling mix (30% houses) where body-corporate costs and apartment supply affect resale, 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.
