The Sovereign uses the Australian Coat of Arms as the base for her own personal Australian flag which is flown, usually as a ‘Standard’ (ratio 22:31), wherever she may be at a particular moment in Australia or when representing Australia abroad.

The crowned ‘E’ set within the seven pointed star used on the national flag brings together both symbols - the Commonwealth and the national flag and the ermine border symbolises the joining together of the States into a Commonwealth. The design of the flag is heraldic.
