Unlike the RAF, RAAF rank abbreviations are always written in uppercase without spaces (e.g. Pilot Officer is written as PLTOFF, not Plt Off).
The rank insignia is very similar to that of the RAF for Corporal and above and for all officers. However the RAAF does not have the ranks of Senior Aircraftman, Junior Technician, Chief Technician or Master Aircrew. In 2022 the RAF renamed their lower ranks of Aircraftman (AC) to Air Recruit (AR) and Leading Aircraftman (LAC) to the ranks of Air Specialist '(Class 2 and 1)' and '(Class 1) Technician' to be more inclusive as they did not have the Aircraftwoman title for female service members. Both officers and airmen wear rank insignia on the chest when wearing General Purpose Uniform or Disruptive Pattern Combat Uniform. Rank insignia is worn on the shoulder in all other orders of dress with the exception of the Service Dress tunic where it is worn on the cuff for officers and lower sleeve for Warrant Officers and the upper sleeve for airmen in their tunic and the sleeve of all enlisted Physical Training Instructors (PTIs) working uniform. The word 'Australia' appears immediately below all rank insignia worn on the shoulder or chest.
^Other joint 3-star positions available to RAAF officers are VCDF, CJOPS, and CCDG.
^Note that although all three ranks are equivalent, and all three ranks are "1 star" positions, an Air Commodore is considered an "Air Officer", a Commodore is considered an "Admiral", but a Brigadier is not a "General". Until about 1922, many Commonwealth nations used the rank of Brigadier General, with a similar rank insignia, but by the end of the 1920s, Australia had replaced it with the rank of Brigadier, and a rank insignia similar to that of the Senior Officer rank of Colonel. Hence, in the Australian army, a Brigadier is a Senior Officer, not a General.
