Warnes is a smaller community of 21 — 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. Household income of $72,748/year is 10% below the South Australia median of $80,964, typically translating into lower entry prices and a tenant base more sensitive to rent increases. Warnes is 193 km from Adelaide, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Separate houses make up 129% of dwellings — 56 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.
