It is used in a similar way as the Royal Standard of the United Kingdom, by signalling the monarch's presence within a building or vehicle in Australia.

Queen Elizabeth II was the first Australian monarch to adopt a personal flag for Australia.

[2] The personal flag of Queen Elizabeth differed from that of Charles III as it was defaced with a gold seven-pointed federation star with a blue disc containing the letter E below a crown, surrounded by a garland of golden roses.

The blue disc was taken from the Queen's Personal Flag, used by her for duties as Head of the Commonwealth of Nations.

At the 2023 coronation of King Charles III, the Australian national flag was used to represent Australia.
