Aboriginals are the original natives of Australia who lived there many years ago. They have certain traditions, which they even keep up till now. Boomerang is a weapon used by them to get their prey. They used to throw them at the target; it reaches the target kills it and then returns back to the person who threw it. These aboriginals were the ones who invented such a peculiar weapon. Another of their invention is the Didgeridoo, which is a musical instrument still famous in Australia.
