I am interested to know who qualifies for the ANZAC sticker, or asked another way, who doesn't qualify? I can find nothing on the ANZAC Project pages that actually addresses this important point.
I note from an early post announcing the project on G2G, Sep 15, 2013, "Paul Bech has now made the Anzac Page a Project ,the Anzac Project is for Australian and New Zealand Military Personnel who fought in any of the wars if you are intrested in this Project just let us know Terry". This could be interpreted as if you didn't "fight", then you don't qualify but I don't think that was the intention of the statement which was merely announcing the start of the project.
Looking elsewhere for inspiration, I found the "Discovering ANZACS" website, which appears to be a site of National Archives of Australia and Archives New Zealand, [https://www.discoveringanzacs.naa.gov.au/]
They offer government records about Australians and New Zealanders in World War I and the Boer War. Again, I don't think they are attempting to define who qualifies, they are merely stating what they have to offer.
What can we agree on?
Try 1. It's limited to Australians and New Zealanders. No I've fallen at the first hurdle. There are plenty of other nationalities represented, and deservedly so.
Try 2. It's limited to Australian and New Zealand Military personnel who served during a war. Getting closer, but what about the nurses and other non-military people who all "served" in their own way. I note Mark Rogers post dated 25 April 2019: "And beyond the Service men and women, there were a lot of others worthy of note, such as the non-military medical staff, Salvos, merchant mariners, munitions workers etc. They also served in their own ways." and Melanie Paul's comment: "Also Land Army girls/women."
I agree with Mark, they are worthy of note, but do they qualify for an ANZAC sticker?
Another group I came across was school and university cadets. Do they qualify? I wouldn't have thought they qualified but I'm not knowledgeable about that organisation's links with the army.
What about someone in the Army Reserves?
It all gets a bit messy and I'm no wordsmith but I think it will require some discussion to get agreement and either a defining statement or at least a set of guidelines which would then take some prominent position on the ANZAC project page.
