DuringWorld War 2, the Postmaster-General's Office together with the Department of War implemented a system of censorship across all communications.
Two approaches were used:
Approach 1: For the Telegraphs received from overseas, an implicit system requiring the sender to compose the message using pre-set code numbers - as described elsewhere. This system made it cheaper for the sender, quicker for the operators and almost no involvement of a censor.
Approach 2: the use of a handstamp applied to any telegraphic message received in Australia to show that the message was acceptable and had been passed by the Censor.
