From a South Africans perspective, this image for me is not necessarily only about WWI but also about Australias involvement in Anglo Boer War in South Africa.
Australians may find it interesting that several significant events took place during the 1899-1902 war:
1. At the start of the war Australia as a commonwealth did not exist.
2. The colonies of Queensland, Victoria and NSW as well as Tasmania were asked by Britian to send troops.
3. Queen Victoria was still on the throne.
4. Queenland and NSW troops took part in the relief of Kimberely in 1900 which was surrounded by Boer troops (Queensland Mounted Infantry and the NSW Lancers).
5. In 1901 Britian had defeated the majority of the Boer armies and was now involved in the worlds first fast moving guerilla war.
6. Also in 1901 Queen Victoria died and was replaced by Edward VII (hence my association with King and country in the photo).
7. In the same year Australia became the Commonwealth of Australia and opted to raise more troops to send to the conflict.
8. That made the Boer War the very first conflict in which the Commonwealth of Australia took part.
9. For me the southern Cross also symbolises the southern hemisphere as a whole though it best known for being included on the Australian and New Zealand flags.
10. Huge sacrifices were made by Australian troops and many thousands died, both from battle and disease!
Apart from the more obvious association with the Gallipoli slaughter fields (and later the trenches in France) that most Australians would think of from this image, for me there is far more to the image!
Just adding another perspective...
Thanks for sharing it with us!
