The Australian White Ensign (also known as the Australian Naval Ensign or the Royal Australian Navy Ensign) is a naval ensign used by ships of the Royal Australian Navy (RAN) from 1967 onwards. From the formation of the RAN until 1967, Australian warships used the British White Ensign as their ensign. However, this led to situations where Australian vessels were mistaken for British ships, and when Australia became involved in the Vietnam War, the RAN was effectively fighting under the flag of another, uninvolved nation. Proposals were made in 1965 for a unique Australian ensign, which was approved in 1966, and entered use in 1967. The Australian White Ensign is identical in design to the Australian National Flag, but with the reversal of the blue background and the white Commonwealth Star and Southern Cross. History Before Australia's Federation, the Colonial navies flew the British Blue Ensign, defaced with the symbol of the relevant colony. When operating outside colonial waters, these ships had to be commissioned into the Royal Navy, and consequently flew the British White Ensign. During the early 1900s, several British dominions, including Australia, began to campaign for the right to create naval forces independent of the Royal Navy, and capable of deploying outside territorial waters. During the 1909 Imperial Conference, Canada and Australia campaigned for this, and suggested that these ships fly the British White Ensign, defaced with an emblem representing the dominion. No binding decision was made on the matter. During the lead up to the creation of the RAN, the issue was raised again: Australian politicians and the public wanted Australian ships to fly a unique ensign, while the British Admiralty wanted them to fly the British White Ensign. Suggested Australian ensigns included the British ensign defaced with a blue Commonwealth Star, or a variant of the Australian national flag. Australian warships used the national flag as an ensign until the formal creation of the RAN from the Commonwealth Naval Forces on 10 July 1911: ships were ordered to fly the British ensign, while the Australian flag was used as a jack to identify their nationality. Australian warships regularly found themselves mistaken for their British counterparts. One attempt to alleviate this was made by the executive officer of during the Korean War, when he had a kangaroo-shaped 'weathervane' made and mounted to the destroyer's mainmast: this became the basis for the red kangaroo symbol fixed to
