Estimated — The Stapledon and WSP series end at 2005 and 2024 respectively. To extend the picture to 2025, we applied reported growth rates to WSP’s last data point (20.4×). Sydney house prices grew approximately 6.5% in 2025 (CoreLogic, PropTrack), while wages grew 3.4% (ABS Wage Price Index, December 2025). Prices rising roughly twice as fast as wages pushes the ratio to an estimated 21.0×.
