Proclamation Day is the name of official or unofficial holidays or other anniversaries which commemorate or mark an important proclamation. In some cases it may be the day of, or the anniversary of, the proclamation of a monarch's accession to the throne. A proclamation day may also celebrate the independence of a country, the end of a war, or the ratification of an important treaty.
Proclamation Day in South Australia celebrates the establishment of government in South Australia as a British province. The proclamation was made by Captain John Hindmarsh beside The Old Gum Tree at the present-day suburb of Glenelg North on 28 December 1836. The proclamation specified the same protection under the law for the local native population as for the settlers. The date 28 December as a public holiday in South Australia was modified to the first otherwise working day after the Christmas Day public holiday (i.e. usually 26 December). Formal ceremonies involving the most senior current officials and politicians, followed by public celebrations, continue to be held at the still-extant Old Gum Tree at Glenelg on 28 December.
The proclamation was printed by Robert Thomas (1782–1860), who came from England with his family on the Africaine, arriving at Holdfast Bay on 8 November 1836. Thomas brought with him the first printing press to reach South Australia. The press was a Stanhope Invenit No. 200, and was on display in the State Library until 2001. It may be surmised that, from the quilled text of the proclamation provided to him by the officials, it was Thomas himself who made a more striking layout for print, later most familiar to the public.
The colonising fleet consisted of 10 vessels which had gathered at Nepean Bay before being directed to Holdfast Bay. The Africaine was the first to arrive, discharging settlers on 9 November 1836, followed by the Emma, the John Pirie, and the Tam O'Shanter. These deliberately preceded Governor John Hindmarsh on the Buffalo to enable preparations including the printing of the proclamation in advance of his formal arrival on 28 December. Thomas's wife Mary (1787–1875) published The Diary of Mary Thomas, in which she described the journey on the Africaine and the early years in South Australia. An extract from the diary reads:
