Cooee

Cooee! (IPA /ku:'i:/) is a shout used in Australia, usually in the bush, to attract attention, find missing people, or indicate one's own location. When done correctly—loudly and shrilly—a call of "cooee" can carry over a considerable distance. The distance one's cooee call travels can be a matter of competitive pride. It is also known as a call of help, which can blend in with different natural sounds in the bush.
