Don, VK6ZYZ suggests the following book:
The best kept secret of World War 2
Here for the first time is the story of those young Australian servicemen and women whose skill in intercepting Japanese military radio signals and code messages provided General MacArthur's intelligence organisation with vital information about enemy operations in the South West Pacific Area.
The RAAF's No. 1 Wireless Unit is featured in this book. Their secret operations were located in a number of houses in French and Sycamore Streets in the suburb of Pimlico in Townsville, before moving to a new location at Stuart in a fortified concrete bunker disguised as an old farm house.
