Melbourne Water publishes 45 open datasets for Australia. Browse them live in Vizzie and turn any one into a map or chart.
Melbourne Water is the open-data portal for Australia, covering Victoria. It runs on ArcGIS Hub, Esri's open-data platform for geographic data. You can browse it directly at data-melbournewater.opendata.arcgis.com.
On Melbourne Water, 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 45 datasets here whose licence Vizzie can identify, essentially all of them can be used commercially; 98% carry a share-alike condition, so work built on them has to be published under the same terms. Attribution is required by almost every open licence — Vizzie writes the attribution line for you when you export or publish.
