The Mace has been used in the House of Representatives since 1951. It was a gift to the Australian Parliament by the House of Commons and King George VI. The gift marked the Jubilee year (50th anniversary) of Australia's federation.
In medieval England, the royal Serjeants-at-Arms carried a mace stamped with the Royal Arms. This was a weapon used to assert the authority of the monarch. By 1415, the House of Commons in the British Parliament had appointed its own Serjeant-at-Arms to serve the members of the House. The tradition of the Mace in the House of Representatives is taken from this practice in the House of Commons.
