It marks the anniversary of the first major military action fought by Australian and New Zealand forces during the First World War. ANZAC stands for Australian and New Zealand Army Corps. At the Australian War Memorial, the ceremony takes place at 10.15 am in the presence of people such as the prime minister and the governor general. Each year the ceremony follows a pattern that is familiar to generations of Australians. A typical ANZAC Day ceremony may include the following features: an introduction, hymn, prayer, an address, laying of wreaths, a recitation, the Last Post, a period of silence, either the Rouse or the Reveille, and the national anthem. After the Memorial’s ceremony, families often place red poppies beside the names of relatives on the Memorial’s Roll of Honour, as they also do after Remembrance Day services.
