Main Roads Western Australia publishes 695 open datasets for Australia. Browse them live in Vizzie and turn any one into a map or chart.
Main Roads Western Australia is the open-data portal for Australia, covering Western Australia. It runs on ArcGIS Hub, Esri's open-data platform for geographic data. You can browse it directly at portal-mainroads.opendata.arcgis.com.
On Main Roads Western Australia, most datasets here are clearly licensed — only a small share are undeclared. It's important to know that "no licence declared" is not the same as public-domain or free-to-use. Undeclared data carries no explicit permission to copy, adapt, or redistribute it — so reusers should treat it cautiously and check with the publisher before relying on it. Vizzie flags each dataset's licence (or its absence) so you can see this before you build.
Of the 690 datasets here whose licence Vizzie can identify, essentially all of them can be used commercially. Attribution is required by almost every open licence — Vizzie writes the attribution line for you when you export or publish.
The state road authority's own catalogue: road network, bridges, heavy-vehicle route networks. 690 of 695 declare CC BY 4.0 and 6 of 6 sampled datasets ingested.
