Exceptions do get made in special cases - if the child of a British soldier killed at Fromelles, came forward and asked for a ticket, for example, it would be allocated immediately - but such a child would be at least 99 years old at this point. The scope for such exceptions to be made is greatly reduced. Understand the Battle of Fromelle is regarded as the worst day in Australia's history. It is the bloodiest day, Australia ever faced in war. We lost more that day, and more were wounded, than on any other single day in our history. No other country can make that claim about this battle and this place. I do not believe it is unreasonable to claim its place in Australian history is different than its place in anybody elses.
For Britain, the equivalent day is generally held to be 'The First Day on the Somme' which took place nearly three weeks earlier - the site of that battle is where the Thiepval memorial is located.
Thanks everyone for educating me on this battle. I’ve never heard of it. My grandfather was in the US Navy in WW I and served on a battleship overseas. He suffered some kind of smoke damage in his lungs that bothered him for the rest of his life. He died in his sixties which was a bit young for his generation and my relatives blame his scarred lings.
