1.
A trainee completing their first year of training at the Australian Defence Force Academy.

Dully's or dullies are well known for performing stupid acts as a result of their lack of military and life experience.

Dullies have always been despised by 2nd and 3rd year trainees at the Academy, however this level of hate has increased since 2010 when the initial training that dullies received was severely softened along with other training such as the Army induction course known as 1 Alpha. This soft training produced a year of dullies who had not been broken in a military sense and still carried their arrogant high school attitudes and their unpromising approach to life. This attitude has proven incompatible with more senior ADFA members creating a greater divide between training year groups.

The word Dully; while now associated with hate, is still primarily tied with incompetent and inexperienced acts; such as accidently volunteering for extra activities and performing drill on the weekends.
Senior Trainee: Did you hear about that Dully? Tried to Beast a SGT for not saluting him.
