Age & Gender
You can join the Army at 17, but start your application earlier if you wish. There are no gender restrictions in the Army.
Age range for recruitment
To apply for a job in the Army you must be at least 16 years and 6 months old, though you can start thinking about a career in the ADF much earlier (see below).
The maximum age for recruitment varies greatly by role, and you'll find details in each job description on this website. As a general rule you can join the Army if you are between three and six years away from the Compulsory Retiring Age for a specific role.
17-year olds in the Army
At this age you are a 'minor' so special conditions apply. Your application must be voluntary, approved in writing by both your parents or your legal guardian(s), and accompanied by an original or certified copy of your full birth certificate.
The Army abides by the spirit and intent of the Optional Protocol on the Rights of the Child on Involvement of Children in Armed Conflict. That means we will take all feasible measures to ensure that minors do not participate in hostilities.
