Referenced, awaiting primary-source reviewAdopted on 1 July 1971. Red and black have long been traditional colours of many Papua New Guinean tribes. The bird of paradise is a symbol of tribal culture, and its soaring position represents the nation's emergence; the Southern Cross signifies their relationship with other nearby countries in the southern hemisphere. The upper triangle is red with a Raggiana bird-of-paradise in gold; the lower triangle is black with five white stars forming the Southern Cross. Designer: Susan Karike.
