Why are there such strict age limits there?
The RAAF states
the maximum age for Direct Entry (Non-Graduate (or Graduate)) Pilot entry is 43 years of age. However, Air Force has a stated preference for pilot applicants that do not exceed 27.5 years of age at the commencement of Pilot training.
The RAN states
Maximum age on entry is 46 years of age.
(up to 51 for observer)(I know of an aircrewman who is 63 and still going!)
Army Aviation
Applicants must be aged between 17 and 49 years of age inclusive on entry.
If they knock you back on age, and you
really want to fly for the military
, you might as well come and do it in the sunshine.
