Serious question here, Are you saying there is no recourse for a victim in Australia?
Lets say you were in a public park throwing your boomerang and playing fetch with your Kangaroo, And the Boomerang fly's out of control and strikes a baby in the face. Now you have a cut baby and upset parents. You just say "OOOOPs sorry mate!" everyone goes on their way and all is good?
Is this the point where the damaged baby is left out in the bush for dingo bait?
There has to be some recourse for innocent victims. Maybe you just cont call it a lawsuit?
