It was built to REMEMBER Australians who went to fight for their country in a far land, knowing there was a damn good chance they wouldn't come back. Many didn't.
No one is going build monuments to remember anti-vaxxers too selfish to take a one in a million chance of blot clots (which are also treatable if you go to hospital when you feel ill).
If they won't take a jab, they certainly wouldn't be willing to fight for our country if needed. Selfish cowards.
