Here's one that should be more permanent:
The picture below is Mitchell Falls from an airplane at high water flow. Click for full-size.
The picture below is from the Web site at the bottom; they don't have a name for this waterfall, but it's impressive. Anybody have an idea? (I don't have time to research it)
OK, I did have a minute, and it’s probably Twin Falls in Kakadu National Park. On the Web site, the picture below this one is even more impressive, and that should be Jim Jim Falls.
Though they couldn’t get there on the ground, these tourists were lucky to see these falls at high flow — the Web site I found the information on indicates that they can dry up. From what I’ve seen elsewhere, northwestern Australia hasn’t been hit hard by the drought, which is really bad in southeast Australia.
WOW!! Now THAT's inspiring! Thanks!
BTW: Do you know about the geology of this region? i.e. are those rock formations that the water is flowing over ancient lava flows?
