I was posted to Darwin for nearly ten years when serving in the army and there is a lot of WW2 sites in the Northern Territory of Auatralia. Everything from Airfields, hospitals, camp sites,AA batteries and dumps. I have found everything from Machine gun barrels, 20 mm spitfire projectiles, ammo can lids, and other bits and pieces, One Airfeild called Fenton has a aircraft graveyard with wrecked B25 and B17 parts scattred for miles. Will post some pics of what is up there. Darwin was bombed by the Japanese by the same carrier group that bombed Pearl Harbour and was a major US and Australian staging area. You can still find bomb damage and bullet holes in bulidings around Darwin to this day!
