Data WA is the place to discover Western Australian public sector data, implemented by Landgate as a whole-of-government service under the WA Open Data Policy. The catalogue brings together datasets from organisations across the public sector in one searchable site.
For geospatial work it connects to Western Australia's Shared Location Information Platform (SLIP), providing cadastre, road network, imagery, and other authoritative spatial layers. Open data is licensed for free reuse and redistribution, typically under Creative Commons Attribution.
