Merriton is a smaller community of 55 — 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. Households here earn $86,632/year on average — 7% above the SA suburb median of $80,964 — a modest premium that supports resilient owner-occupier demand. Merriton is 171 km from Adelaide, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand.
