I haven't read this book yet, but it's been recommended to me twice and Brett Freeman refers to it in Lake Boga at War. At the moment, all I can say is that it's about RAAF Catalina squadrons and has quite a few WWII-era photos. It is one of the few books in my list that is still in print, meaning you won't have to pay an arm and a leg to get a copy. But I wouldn't wait too long...
