There is a compulsory introductory course with those not having a prior law degree, then 12 electives. What got my attention was that there are two defence related courses offered: Cyber Warfare Law (LAWS8035), Weaponry and Targeting (LAWS8401). Also #MeToo and the Law (LAWS8403), looks interesting.
The certificate courses can be credited towards a Masters program, but as Tim pointed out in the seminar, you have to thing about your program of study.
ps: I will be speaking on "Designing for scale: How to use mobile devices to recruit, train and equip the extra 18,500 defence personnel", at the Mobile Learning Special Interest Group meeting of the Australasian Society for Computers in Learning in Tertiary Education (ASCILITE), 10 am, Friday, August 26, 2022.
