It’s a hundred years since Australia and New Zealand’s involvement in World War One.

London joined Australia, New Zealand and other countries globally, to remember those who fought and lost their lives at Gallipoli, Turkey, against the Ottoman Empire during the war.

Over ten thousand men from both countries were killed during the battle of Gallipoli.

All of them were volunteers.
