Data sources & licences
Keys brings together official Western Australian, Australian and open-data sources. We attribute each source and use it under its respective licence. Keys is not affiliated with, or endorsed by, any of these agencies or providers. All information is indicative only — always verify with the official source before any decision.

Data we don't display — look it up at the official source
Some Western Australian government layers are licensed for personal or internal use only, which does not permit us to display them publicly. So Keys doesn't show these — instead, here are the official tools where you can look them up for your own property, for free.
