Australian forces turned back the Japanese attempt to capture Port Moresby, and began the drive ot oust Japanese forces from New Guinea.
The Tank was actually introduced in the Battle of Somme in WWI, though it was not very useful because they were very slow and un-reliable. They improved for WWII, and also the weapons were very much advanced in the way that they were more accurate and powerful...
Them most important Allied people were Winston Churchill, Gen Eisenhower, Gen Omar Bradley, Gen Bernard Montgomery.
If you would care to read the documents on the Australian POW's in Germany were much better treated, in a more humane way then the ways that the Japanese were treating the Australians. Although it still must be looked upon. Hope I Could help :)
Perhaps you could find and old history teacher at your school, and ask if they know where any of their old history teachers live or can be contacted.
You are trying for something very difficult.
Most young people were drafted or joined during the Second World War, so the only history teachers that would be left were those with a physical problem, or were too old to be in the military. That means they would be about 92 years old today.
Best of luck, John
Social studies was not taught as a school subject at that time, so bits of social studies would have been taught in History, Econmics and Civics.
