Flag Adopted: 3 September 1901
Flag Proportion: 1:2
Use: Unofficial Civil Ensign and unofficial National Flag on Land
The Australian colonies of New South Wales, Tasmania, Western Australia, South Australia, Victoria, Queensland (and later Western Australia) federated to form a nominally independent country on 1 January 1901. However, at the celebrations to recognise the formation of the Australian nation, Australia had no national flag to fly.
Australia's first `Federal' flag was chosen from a public national flag competition held in 1901. Two designs were required: one for the "merchant" service (i.e merchant use at sea) and one for "official" (i.e Government) use. The competition attracted 32 823 entries. Australia's first Prime Minister, Edmund Barton, announced the winning designs in Melbourne on 3 September 1901.
The winning design for "merchant" use is shown above. In accordance with British ensign convention, this "merchant" flag was a British red ensign, defaced with a 5-star Southern Cross and a large single star called the Federation Star.
The Southern Cross was represented by stars ranging from 5 to 9 points to indicate their relative apparent brightness in the night sky. Directly below the Union Flag was the large six pointed white federation star, representing the federation of the six colonies of Australia in 1901.
Note that this flag was officially intended only to be used by merchant ships registered in Australia and citizens at sea. It was expected that citizens on land would continue to fly the Union Flag (indeed this is corroborated by the Flags Act 1953 - citizens are "entitled" to fly the Union Jack).
