The badge of Aust Int Corps, which was modeled on the British Army Intelligence Corps badge and accepted in 1953, has the motif of a white and red Tudor rose flanked by laurel leaves and resting on a scroll inscribed 'Australian Intelligence Corps'. A crown surmounts the whole motif.

The rose symbolises security, which is derived from the Cromwellian use of a rose displayed to indicate when secret matters were being discussed. The laurel wreath depicts honour and the crown represents allegiance to the sovereign.
