Hi Mezza, windy.com already has the "Weather Radar" feature, scroll to the bottom of the Show/add more layers menu It's the 2nd from the bottom on a computer web browser.
I doesn't include Australia and depending on copyright, etc the raw (BOM) images are available to the public/non-commercial use.
Don't you think this would be useful? It wont restrict your research/data accuracy in any way.
