It's Anzac day on Friday, commemorates all Australian veterans and soldiers who have died in past conflict, especially the diggers that died at Gallipoli (known as Anzacs: Australia and New Zealand Army Corps).
"They shall grow not old, as we that are left grow old:
Age shall not weary them, nor the years condemn.
At the going down of the sun and in the morning,
We will remember them
Lest we forget"
