Adelaide Cup Day is held on the second Monday in March in South Australia (held in May before 2006).

Proclamation Day is the South Australian public holiday that celebrates the proclamation of South Australia as a British province. The proclamation was made by Captain John Hindmarsh, beside The Old Gum Tree at Glenelg, on 28 December 1836. The proclamation included the same protection under the law for the local native population as for the settlers. It is now a public holidayin South Australia, although this holiday is held on the first otherwise working day after the Christmas Day public holiday (usually 26 December). Formal ceremonies and celebrations are always held on 28 December.
