Australia is both a federation and a constitutional monarchy. The Commonwealth of Australia Constitution Act 1900, which made the Australian Constitution law, refers to the establishment of the federation “under the Crown of the United Kingdom of Great Britain and Ireland.” In fact, however, since 1973, the appropriate style of the monarch in relation to Australia has been “Queen of Australia.” And ever since federation, the monarch has been represented in Australia by a Governor-General, who progressively has acquired a more significant role, in parallel with the acquisition of Australian independence.
