The soldiers of the Australia and New Zealand Army Corps - ANZACs for short - were well known for their slouch caps and jaunty attitudes! Here's a colouring page of an ANZAC soldier to print.
This lovely free Remembrance Day colouring page features poppies for remembrance and a banner with the traditional words "Lest we forget". It would also make a good Anzac Day colouring sheet, of course.
Many brave soldiers from the ANZACs as well as from Great Britain and South Africa (and of course from Turkey) fought at Gallipoli. Design an appropriate medal using this outline, and colour it in.
