Grandpa on Mums side (never met) was scheduled to fight in the South Pacific but his unit for whatever reason did not go. He fought at the Battle of Darwin. At wars end he was going to be stationed in Japan during the occupation, but Nanna had a child on the way so they decided not to send him. Nearly forgot. He was on his was to North Africa but it was found out he was too young. Other Grandpa was too young to participate in WW2. Nannas Brother was a tail gunner, I can not remember where yet I do suspect North Africa. My Nannas Cousin im sure fought in some theatre in World War 2. Yet apparently the rumour is he underwent war experiments that embittered him. Could tie in with Marilinga (Nuke bombings) but its never been confirmed. Mum Had cousins who fought in Vietnam, one as a scout. Apparently some Bikers were giving him cheek or trying to fight him. They got beat an apparently one asked where he learnt to fight like that. He just replied "Vietnam" Military history prior to that is sketchy. Unsure if any direct relatives fought in WW1.
