The current state flag of the Northern Territory was officially adopted by the Northern Territory, Australia in 1978. The Northern Territory has been in existence since 1911, but could not hoist its first flag until self-government in 1978.
The Flag of the Northern Territory was officially acknowledged and raised for the first time in a ceremony celebrating self-government, on the esplanade in Darwin, the Territorial capital, on 1 July 1978. The ceremony was further acknowledged by a 19-gun salute from HMAS Derwent. As the Northern Territory never had colonial status or a prior flag, it was decided that an original design would be created. The flag was designed by Robert Ingpen, a prominent artist originally from Drysdale, Victoria. Ingpen used a number of designs suggested by the public as a basis for his final design.
