I've expanded the map of Australian Football League grounds to included all grounds ever used to stage official AFL matches. Current grounds are indicated by a large red marker, and old grounds have a small yellow marker. I've also set the map to start up in hybrid mode, so you can more easily appreciate the views of the grounds from above.
An noted on the page, there are a few grounds missing. I shall add them if I become aware of their exact latitudes and longitudes, though I fear this may be difficult if some grounds have been built over.
