Flag Diamond Jubilee Elizabeth 2

The Diamond Jubilee of Queen Elizabeth II is the planned international celebration in 2012 marking the 60th anniversary of the accession of Queen Elizabeth II to the thrones of seven countries, upon the death of her father, King George VI, on 6 February 1952. Queen Victoria in 1897 is thus far the only other monarch in the histories of Britain, Canada, Australia and a few other Commonwealth realms to have celebrated a Diamond Jubilee.

Quentin Bryce, the Governor-General of Australia, announced that the Diamond Jubilee will be celebrated "with a host of national and community events throughout the Commonwealth." In that vein, it was said in late 2011 that the government of Queensland was planning to declare a holiday in June 2012 to mark the jubilee and that Prince Charles, Prince of Wales, and Camilla, Duchess of Cornwall, would tour the country.

The Royal Australian Mint announced in August 2011 that it will be releasing a silver proof 50 cent coin to celebrate the Queen's Diamond Jubilee.
