Although I have slept out on the ground wihtout benifit of any thing but the shirt on my back, in Africa (Tanzania) I do not relish the thought of it...Australia does not have Lions, Hyenas, elephants and Buffalo herds roaming about, not to mention Black Mambas, Hippos and a croc or two if your close to a water source. or I suspect that they would have abandoned the swag idea a century ago...Anyway thats why you don't see them I would guess..

We have some simuliar "bedrolls" and pop or pup tents in the USA...
