The first Anzac Day was formally commemorated on the anniversary of the landing at ANZAC Cove, marking a significant moment in the collective memory of Australia and New Zealand. Communities across both nations organized various ceremonies, primarily characterized by dawn services, which reflected both mourning and gratitude for the sacrifices made by the soldiers. These events took place in towns and cities, drawing together families, returned servicemen, and civic leaders in a united act of remembrance. In Australia, towns such as Sydney and Melbourne saw large gatherings, while in New Zealand, cities like Auckland and Wellington held their own observances.

During the ceremonies, speeches were delivered honoring the courage and endurance of the ANZAC troops who fought bravely in the face of adversity, particularly during the Gallipoli campaign. The events were heavily influenced by the emotional weight of World War I, as families were reminded of loved ones lost or traumatized by the conflict. Song, poetry readings, and the playing of the Last Post were common features of these gatherings, instilling a sense of shared national identity and collective grief.

Organizers aimed to foster a spirit of ANZAC bravery and mateship, elements that would become foundational to the commemoration's enduring legacy. The significance of the day extended beyond mere remembrance; it evolved into a national occasion that solidified the connection between the two nations and their efforts in the war. In subsequent years, Anzac Day would grow in prominence and significance, leading to its status as one of the most important national days in both Australia and New Zealand.
