Nothing to be scared about, here, in Oz! Are you kidding!
My most terrifying experience came some 20 years ago in the Wollemi National Park, the same one that hid the 'dinosour' pine.
I don't talk much about it as doing so aggrivates shingles I get so anxious about it.
I was camping alone in the park, way back then. The site took me two day's hike to reach on foot. Marvellous site too- creek side, green due to recent rain, and very, very isolated.
While setting up the tent, a big, old grey boomer came hopping close by along the creek's shoreline, thump, thump, thump.
Suddenly, no sooner did it go under a huge gum tree, BAM! A drop bear fell down onto the unsuspecting boomer's back, the roo more concerned with my presence than the danger up in the tree. The vile creature yanked the boomer's head back, and its enourmous fangs sank into the roo's soft throat! The roo hit the deck, drop bear was flung of its back, only to race back to the writhing boomer to finish it off!
The screams of the drop bear as it fed aged me 20 years! I was so scared I dropped the gear in my hand and ran for my life! I made it back to my car in only a couple of hours.
I've never returned to the Wollemi since.
I've been told that the Pilliga State Forest is the only other lone bastion of the drop bear. You never, ever stop overnight at the Pilliga SF! Heaven's above, if the Pilliga SF is not too far from Coonabarabran too! You never hear about the lone astronomers who have gone outside of their observatories for a slash during the night, and have never returned! There's not a 5m high electrified fence around the obs for no reason!
