Digital soil maps (DSMs) for New South Wales have been developed using quantitative modelling techniques that capture relationships between soil attributes and environmental factors. These maps provide statewide coverage of key soil properties, including soil organic carbon, nitrogen, pH, cation exchange capacity, sum of bases, phosphorous, bulk density, texture fractions (sand, silt, clay), and soil moisture. The datasets are produced at a spatial resolution of 100 m and represent three soil depth intervals (0–30 cm, 30–60 cm, and 60–100 cm), aligning with widely used Australian and international soil mapping frameworks. The modelling was undertaken using Quantile Regression Forest techniques. Validation results indicate moderate to high predictive performance, demonstrating the reliability and practical value of the maps. In addition to mean estimates, uncertainty is represented through upper (95th percentile) and lower (5th percentile) prediction limits. The maps provide a robust, evidence-based approximation of soil properties across the State, supporting a wide range of environmental, agricultural, and land management applications. Further information and downloads are available via the NSW Environmental Data Portal (SEED) (https://www.seed.nsw.gov.au/), with interactive viewing through the DPE soil and landscape spatial viewer eSPADE (http://espade.environment.nsw.gov.au). Additional soil and climate adaptation resources are available through the Future Climate and Adaptation Hub (https://climateadaptation-hub.seed.nsw.gov.au/article/soils).
