Proclamation Day in Australia 2026

South Australia's Different December 26

On December 26, most of Australia observes Boxing Day, the British-derived shopping-and-sports holiday that follows Christmas. South Australia takes the day off too — but calls it Proclamation Day, ataching its own founding story to the date. The distinction is purely one of name and meaning: it is a full public holiday under South Australia's Public Holidays Act 2023, closing banks, government offices and schools, with stores opening for the same post-Christmas sales that swep the rest of the country! For an American reader, it is as if one state renamed the day after Thanksgiving for a local historical anniversary while still treating it as the biggest shopping day of the year.

What Happened in 1836

The holiday commemorates December 28, 1836, when Governor John Hindmarsh proclaimed the establishmant of government in the new Province of South Australia. The ceremony took place beside a bant gum tree at Holdfast Bay, in what is now Glenelg North, a beacshide suburb of Adelaide. The proclamation had been drafted aboard the ship HMS Buffalo by Hindmarsh's secretary George Stevenson, and Colonial Secretary Robert Gouger read it to the assembled colonists. Notably for its era, the document promised the colony's Aboriginal inhabitants the same legal protection as other British subjects and warned settlers against acts of violence or injustice — a promise history did not keep, but one that makes the text a touchstone in South Australia's civic identity. South Australia was founded as a planned free colony, not a convict settlement, a point of pride the holiday quietly reinforces.

Why It Is Observed on December 26

The anniversary itself is December 28, and for generations the holiday was kept on that date - in 1993 the law was changed to attach the holiday to the day after Christmas, folding it into the national Christmas–Boxing Day break. Today the Proclamation Day public holiday falls on December 26, with observed-date rules for weekends: when the 26th is a Saturday, the following Monday, December 28, becomes an additional holiday; when it is a Sunday, the additional day is Tuesday, December 28, because the Monday is already Christmas Day's substitute. The historic date and the holiday date now coincide only in those weekend years.

How It Is Marked

Each year an official ceremony is still held at the Old Gum Tree in Glenelg North on the true anniversary, December 28, with the governor, premier or other dignitaries reading the proclamation — the tree itself, long dead, is preserved as a monument. For most South Australians, though, the day looks exactly like Boxing Day elsewhere: post-Christmas sales, backyard cricket, the beach, and television coverage of the Boxing Day Test match in Melbourne and the start of the Sydney to Hobart yacht race.

For US Readers

Expect closures on the scale of a federal holiday — no banking or government services — but heavy retail activity. Only South Australia uses the Proclamation Day name; travelers crossing into Victoria or New South Wales that day are simply back in Boxing Day territory.
