The 25th of April was officially announced as Anzac Day in 1916 to mark the anniversary of the Gallipoli, the first military action fought by New Zealand and Australian forces during the First World War that led to major casualties.

Australians mark the occasion in many ways, including dawn services, “gunfire” breakfasts and sporting contests. One of the other ways many people choose to celebrate the spirit of the diggers is with a game of two-up. The game is often played in Returned Servicemen’s League (RSL) clubs, pubs, and hotels across Australia. But what exactly is two-up, and why is to so synonymous with Anzac Day?
