General Service recruits for the Naval Service recruits must be 18 years of age or over and under 27 years of age on the date deemed as the closing date for applicants. The age requirements for Cadets are as follows:-
Applicants must be 18 years of age or over and under 26 years of age on a date specified in the terms and conditions for the relevant cadet competition. For the 2019 Cadet Competition, the date specified is the 1st September 2019.
