How to read these Australia figures. The cost is the US national midrange benchmark adjusted by a Adelaide, AU cost multiplier (0.90×) and shown in AUD. The “% recouped at resale” is a national (US-derived) Cost-vs-Value benchmark applied to the local cost — it is not a locally measured resale figure, and real recovery varies by Australia market conditions.
