Flag Adopted: 1911
Flag Proportion: 1:2
Use: Naval Ensign
When the Royal Australian Navy was created in 1911, all its ships flew the White Ensign of the UK, i.e. the Royal Navy Ensign. This flag consisted of a white field quartered by a red St George cross, with the Union Flag of the UK in the canton. Australian naval forces "fought under" this flag in the two World Wars and in the Korean War.
In March 1967, the Holt Government adopted a new design, one consistent with the design of the other two Australian Flags but with a white field. This was done at the request of the British Government because the British Royal Navy was not involved in the Vietnam war.
It is interesting to note that this change occurred virtually without opposition.
