Ah, the RAN was protecting Australia, PNG or somewhere, and we were protecting Australian goods convoys to England, North Africa (when we were there) and protecting the fishing fields or someting down near Antartica.. and we fought alongside the US at Coral Sea.
So considering what we had and how big our Navy was, i think it was good.
oh btw, our Navy was the 5th largest in the world at the end of world war 2
