Crocs and emu aren't poisonous. I know, because I've eaten them (and they're both mighty delicious!). Spent 3 weeks in Cairns about 10 years ago, was beautiful.

Little did I know back then though, that a shrub in the rainforest above Cairns has a plant called the Brushwood Shrub, that has baseball sized berries on it, that have been found to kill cancer. 24 hours after it is injected into the cancer, the cancer liquifies and is completely gone. Pretty remarkable stuff, yet the FDA still hasn't moved forward with it.

Anyways, Australia is pretty amazing.
