Australia is generally seen as a dry continent, with vast desert vistas, but the northeast coast extends into the tropics and includes some unique and extraordinary rainforests. We took a railway to Kuranda (admittedly a tourist magnet, but a nice place to visit), and passed the mostly dry Barron River Falls (large hydroelectric dams upstream). The barren rock suggest the falls must be spectacular when full.
The other spectacular locality was the extraordinary Great Barrier Reef, which will no doubt suffer some serious damage as the storm surge rushes towards shore. They do the tours quite well, and we were able to snorkel and take a mini-sub tour of the reefs themselves. I count the experience as one of the pivotal events of my geologic life. It was like going back in time to the vast reefs of Paleozoic time that once covered large areas of the American west. It's one thing to see the quiet echo of fossilized life in the rocks and another to see the reefs full of life in the present day.
