drops bears are okay just wear a pointy hat.Snakes are fine, it's the drop bears you need to worry about...
Really it's the land sharks you have to be careful of.
Townsville had a fair few snakes obviously enough but the worst place I ever went was a hike along Mt Barlow. in a roughly 3hour hike we came across probably 30-40 of them. my favourite was the tree snake about a foot from dads head. He nearly pulled off a ninja backflip to evade. and by ninja backflip I mean he just fell the hell down.
