Thanks for the suggestions on the Australian/PNG aviation heritage books.
Currently reading "
Night Fighter over Germany" by pilot
Graham White about his exploits (often humorous) in the RAF No.100 Group 1943-45.
From age 17 when he volunteered then through training in Arizona and on to electronic intercepting of Luftwaffe fighters over Germany in Mosquitoes.
So far a very good read. It was loaned to me by a friend of the author but can be found
