Australian Defence Force Ensign

The Australian Defence Force Ensign is a flag of Australia which represents the tri-service Australian Defence Force. The flag was declared a "Flag of Australia" under Section 5 of the Flags Act 1953 on 14 April 2000.

The Royal Australian Navy and Air Force have ensigns, the Royal Australian Navy Ensign and the Royal Australian Air Force Ensign. The Army has historically used the Australian Flag. The Defence Ensign is supposed to be used in the case of joint activities. It is made up of three vertical bands: dark blue, red and light blue, representing the navy, army and air force respectively. In the centre is a large joint services emblem in yellow. This emblem features an anchor, crossed swords and a wedge-tailed eagle with wings outstretched combined above a boomerang and below a crest featuring a seven pointed Commonwealth Star.

The rank flags of staff with joint services commands, such as the Chief of Defence Force and the Minister for Defence, are derived from the Defence Force Ensign.

Flag of Australia

The flag of Australia is based on the British maritime Blue Ensign – a blue field with the Union Jack in the canton or upper hoist quarter – augmented or defaced with a large white seven-pointed star (the Commonwealth Star) and a representation of the Southern Cross constellation, made up of five white stars – one small five-pointed star and four, larger, seven-pointed stars. There are other official flags representing Australia, its people and core functions of government.

The flag's original design (with a six-pointed Commonwealth Star) was chosen in 1901 from entries in a competition held following Federation, and was first flown in Melbourne on 3 September 1901, the date proclaimed as Australian National Flag Day. A slightly different design was approved by King Edward VII in 1903. The seven-pointed commonwealth star version was introduced by a proclamation dated 8 December 1908. The dimensions were formally gazetted in 1934, and in 1954 the flag became recognised by, and legally defined in, the Flags Act 1953, as the "Australian National Flag".
