yeman flag, and christmas islands flag
The red, white, and black tricolour formed the basis of the flags of both North and South Yemen. Effective date 22 May 1990.
The flag of Christmas Island was chosen from a flag competition held in 1986 and announced on April 14, 1986. There were 69 entries in the competition which had a prize of $100 (Australian). The winning design was created by Tony Couch of Sydney, who had worked on the island for 4 years as a phosphate mining rigging supervisor. Although the flag was selected, its status has not been officially approved by the Christmas Island Assembly.
