Great Seal of Australia

The Great Seal of Australia (also known as the Great Seal of the Commonwealth of Australia) is one of Australia's national symbols. It is used on some important documents (such as officer commissions, judicial appointments and letters-patent for royal commissions) to demonstrate the approval of the Commonwealth. As the imprint of the seal could not be easily reproduced by government printers, its presence is shown by the initials "L.S" for locus sigilli (the place of the seal) on copies of sealed documents. The current design was authorised by royal warrant on 19 October 1973. The Department of Prime Minister and Cabinet currently holds custody of the seal.

The current design features the coat of arms of Australia, beneath the words Elizabeth the Second and above the words Queen of Australia. Upon the then monarch's death and the ascension of Charles III to the Australian throne, the governor-general approved the use of this seal, pending the approval of a new one by the current monarch.

History
The first great seal was chosen in 1901 by the Commonwealth government and depicts on one side the arms of Great Britain surrounded by the arms of the States of Australia. The other side depicts a woman on a charger, carrying a shield with a Union Jack design and in the hand a palm. Behind her is an image of the sun and beneath is the words Advance Australia. It was designed via competition, with entries by Bulletin cartoonist DH Souter and painter Blamire Young chosen for the design. It also features on the Mace of the House of Representatives.

The second design was authorised by Elizabeth II on 17 February 1954 while presiding over the Federal Executive Council in Canberra during her first visit as reigning monarch.

The third and current design as was authorised by Elizabeth II on 19 October 1973 during another of her visits to Australia. On this occasion, the Queen also took on the style Queen of Australia, signifying the separate constitutional identity of the monarch from her role in other Commonwealth realms.

Queensland
The letters-patent establishing the colony of Queensland as an entity separate from New South Wales granted the governor the authority to keep and use the "Great Seal of the Colony". The only surviving depiction of the seal is a hand seal for wax impressions, which depicts Queen Victoria on the Coronation Chair. It is held by the Queensland Museum. After federation, a new seal design was created, which depicted the coat of arms of the UK held by a lion, next to the coat of arms of Queensland held by a kangaroo, above a banana tree. It was designed by Mr JW Purvis, a die maker and engraver following a public competition. The inscription of the seal changed on the ascension of each monarch and the change of style of Queen Elizabeth II to Queen of Australia. The most current inscription reads "ELIZABETH THE SECOND BY THE GRACE OF GOD QUEEN OF AUSTRALIA AND HER OTHER REALMS AND TERRITORIES IN THE COMMONWEALTH".

Western Australia
The great seal of Western Australia depicts the Royal Coat of Arms of the UK above a black swan. It was used from 1837 until at least 1952.

New South Wales
Under the New South Wales constitution, the governor formally provides, keeps and uses the "Public Seal of the State". In fact, the seal is kept at the New South Wales cabinet office and is used by government officials. On 17 January 1861, the governor demanded to use the seal on a deed, however the premier advised against this and threaten to resign if the governor acted otherwise. The governor insisted he be given the seal, so the premier did so, but resigned along with the rest of the ministry. The governor then relented, returning the seal and refused to accept the resignations. However, the governor later fled Sydney on the day of his term expiring in order to avoid a censure motion, being debated in Parliament on the same day.

The first seal of the New South Wales government was granted by King George III in 1790. Its design was used for the second seal in 1817 and a third seal in 1827. It depicted convicts landing at Botany Bay, taking off their shackles and engaging in Industry. The description for the seal in its royal warrant is as follows: "Convicts landed at Botany Bay; their fetters taken off and received by Industry, sitting on a bale of goods with her attributes, the distaff, bee-hive, pick axe, and spade, pointing to an oxen ploughing, the rising habitations, and a church on a hill at a distance, with a fort for their defence. Motto: Sic fortis etruria crevit [So, I think, this is how brave Etruria grew]; with this inscription round the circumference, Sigillum Nov. Camb. Aust. [Seal New South Wales]" The fourth seal granted in 1832 by King William IV modified this design, inserting the royal arms above the convict symbolism. The fifth seal granted on the ascension of Queen Victoria kept this design, but removed without explanation the motto Sic fortis etruria crevit (a quote from Virgil's Georgics alluding to the rise of Etruria and the Etruscans and the future greatness the colony could aspire to as a result of expansion of agriculture and industry).

The sixth seal was granted in 1870 removed all references to the convict past of New South Wales and instead emphasised the agricultural prosperity of the colony. The convict imagery was replaced by a golden fleece between two Prince of Wales' feathers beneath the royal arms above nine stars. The golden fleece had become a symbol of New South Wales and it depicted on the current coat of arms. The feathers were a pun referring to the colony's name, while also referencing chivalry and the ancient Principality of Wales.The shedding of convict emblems reflected the increasingly distinct personality the colony had compared with the imperial mother country.

In 1912 the seal's design was changed to include the coat of arms of New South Wales. At least by 2004, the seal depicted a hybrid of the New South Wales coat of arms and the royal arms, with the rising sun that appears above the shield of the NSW arms replaced with the shield of the royal arms. Around the edge of the seal were the words "NEW SOUTH WALES" and "ELIZABETH II D G BR TERR AVST REGN SVORVM CET REG CONSORTIONIS POPVLORVM PRICEPS F D" meaning Elizabeth II, by Grace of God of Great Britain, Australia, and of her other Realms and Territories Queen". In 2004, consideration was given to changing the seal to remove the depiction of the royal arms.

Victoria
As of 2006, the seal of Victoria depicts the royal arms on the top half and sheep grazing on the bottom half. Inscribed around the outside is "Elizabeth II Dei Gratia Britanniarium Terrae Australis Regnorumque Suorum Ceterorum Regina, Consortionis Populorum Princeps, Fideo Defensor".
