But the story of the cable girls is interesting. They decrypted/encrypted the cables between Churchill, Curtin (our PM) and the US president at the time. Our PM was desperate, and it shows in the cables. Our troops, what there was of them, were diverted to Burma (to protect the rubber plantations for the British if I remember rightly).

West Block was next to parliament house at the time, before the new one was built.
