Fourth crowned portrait of HM Queen Elizabeth II facing right, wearing the Girls of Great Britain and Ireland tiara.

The Girls of Great Britain and Ireland tiara was a wedding present in 1947 from her grandmother, Queen Mary, who received it as a gift from the Girls of Great Britain and Ireland in 1893 on the occasion of her marriage to the Duke of York, later George V. Made by E. Wolfe & Co., it was purchased from Garrard & Co. by a committee organised by Lady Eve Greville. In 1914, Mary adapted the tiara to take 13 diamonds in place of the large oriental pearls surmounting the tiara. At first, Elizabeth wore the tiara without its base and pearls but the base was reattached in 1969. The Girls of Great Britain and Ireland Tiara is one of Elizabeth's most recognisable pieces of jewellery due to its widespread use on British banknotes and coinage.

Australian rules football, officially known as Australian football, or simply called Aussie rules, football or footy, is a contact sport played between two teams of eighteen players on an oval-shaped field, often a modified cricket ground. Points are scored by kicking the oval-shaped ball between goal posts (worth six points) or between goal and behind posts (worth one point).

The sport's origins can be traced to football matches played in Melbourne, Victoria in 1858, inspired by English public school football games. Seeking to develop a game more suited to adults and Australian conditions, the Melbourne Football Club published the first laws of Australian football in May 1859, making it the oldest of the world's major football codes.

Australian football has the highest spectator attendance and television viewership of all sports in Australia.
