Modelled, not measured. Prices are the Adelaide median house price of the day (rounded, dollars of the day) scaled to where Seaford sits against the city median in 2026, blended toward the median for earlier decades because suburbs move up and down the ladder. Wages are national average full-time earnings. Treat every figure as "about". For actual sales history, ask an agent or the state valuer.
