Hi, thanks for your question.
The Mace used in the House of Representatives was a gift to the Australian Parliament by the House of Commons and King George VI in 1951. It was made in London by Messrs. Garrard, goldsmiths to the monarchy in England. When designing the Mace they consulted the Australian Parliament, who asked that it should resemble the Mace used by the British Parliament, which is also golden and topped with a royal crown.
Our Mace was designed to include symbols of Australian history and culture. The head of the Mace shows the Australian Coat of Arms, including a kangaroo and emu. There are also emblems for the 6 states of Australia. There is also corn, grain and rams’ heads, which the show the importance of agriculture to Australia’s economy.
