Hi Dave,
Some sites that will give you an insight into the involvement of Australia in WW2.
A short synopsis:

A short overview and synopsis of the four services:
http://www.ww2roll.gov.au/doc/overview.asp
I am presently involved in the collection of the headstones or memorial photos of the 10,835 RAAF deaths during ww2 (1939 - 1945). The burials are located in 1066 cemeteries in 65 countries.
If you have any students who have family who may have died during ww2, we
might be able to chase up a photo of their headstone.
Also, depending on where your school is, we may be able to trace a local persons headstone for you. This may provide a better local content.
Cheers
Geoff
