The flag of Papua New Guinea (Tok Pisin: plak bilong Papua Niugini) was adopted on 1 July 1971. In the hoist, it depicts the Southern Cross; in the fly, a Raggiana bird-of-paradise is silhouetted. The design was chosen through a nationwide design competition in early 1971. The winning designer was Susan Karike, who was 15 at the time. Red and black have long been traditional colours of many Papua New Guinean tribes. Black-white-red was the colour of the German Empire flag, which had colonised New Guinea prior to 1918. The bird-of-paradise is also found on the national coat-of-arms. The Southern Cross shows that it is a country in the Southern Hemisphere and can be seen in Papua New Guinea.
