The Territory of Christmas Island is a Federal territory of Australia in the Indian Ocean, 2,600 kilometres northwest of Perth and only 360 km south of the Indonesian capital Jakarta. The local Shire has officially adopted a flag, designed by Tony Couch, that had been unofficially in use since 1986. The blue and green diagonal panels represent the sea and the island's vegetation, a small map of which is included in the centre. The main emblem is a Golden Bosun Bird, a sub-species of the White-tailed Tropicbird.
