Inauguration of Miranda, Queen of Australia

The inauguration of Miranda, Queen of Australia took place on 26 October 2014, in which Miranda was formally inaugurated as the first monarch of the Federation of Australia, which succeeded the former Commonwealth of Australia on 15 October 2014.

Held at the Sydney Opera House in Sydney, Australia, the ceremony served as the formalisation of Miranda's reign as Queen of Australia, with the former Australian supermodel and businesswoman having then took the throne in that same year at the age of thirty-one.

Although a largely simple and short ceremony, with the occasion lasting no more than four hours long, it saw the attendance of a number of world leaders, including Charles, Prince of Wales, whom attended as Queen Elizabeth II's representative, President of France François Hollande, Prime Minister of New Zealand John Key, President of Indonesia Joko Widodo, and Vice President of the United States Joe Biden. The occasion was otherwise presided by the last Governor-General of Australia, Peter Cosgrove, whom, in the major highlight of the occasion, hands over a physical seal of the Australian coat of arms towards Queen Miranda as a symbolic gesture marking the formal end of the British monarchy in Australia, and therefore, the role of governor-general itself, which became effectively extinct.
