The BoM animations are excellent (and not a little mesmerising, especially towards the tropics, the Indonesian fires are quite prominent)... but they're not the highest resolution imagery, which you can get at
himawari8.nict.go.jp/ The controls are a lot less self-explanatory and clunkier, but it is possible to get animations there too, and zoom in on uncompressed versions of the images on the Bureau's site to a true 1km/pixel. But for most practical purposes, the Bureau's images and animations are great, could watch the clouds swirling for hours!
