Anzac Day is on the 25th of April.
Originally Anzac Day was devised as a way to honour the members of the Australian and New Zealand Army Corps who fought at Gallipoli in World War I. Nowardays, Anzac Day is a national day of remembrance to commemorate Australians and New Zealanders who served and died in all wars, conflicts and peacekeeping operations.
Wreaths have traditionally been laid on graves and memorials in memory of the dead. For Anzac Day wreaths, it is quite common to use rosemary, which is symbolic of remembrance. Another commemorative symbol used in Anzac Day wreaths is laurel foliage, historically used by the Ancient Romans when crowning victors and the brave as a mark of honour.
