Our favorite resourceful silent Australian has something new– a stone sling.
A sling is a weapon for throwing stones with greater force and range than by hand alone. It consists of a pouch and two lengths of cord. A rock is placed in the pouch and the two ends of the cords are held in the hand. The sling is then swung over the head to gain momentum. The sling is then swung forward in a throwing action and one end of the cord is released causing the pouch to open releasing the stone to fly at the target.
The ancient Greeks, Romans and Persian employed slingers to great effect in combat. And of course, as related in the First Book of Samuel, a ruddy youth named David used a sling and a stone he picked up off a wadi bed to fuck Goliath up for good.
Might have to try slinging one day.
