Getting Ready to Stand on My Head!

In just 24 hours I'll be headed for Oz, visiting my sister and her husband in Australia. It's 18 years since I've been Down Under, so I can't remember if the water in the toilet flushes clockwise or counter-clockwise. I do rememeber that the night sky is amazing, and I'm looking forward to seeing the Southern Cross, Centaurus and the Magellanic Clouds again.
