Cheers Aximus, I ended up getting a call for the 1st of November FSP too, will see you up there!
Hey Spider01,
They'll likely ask you questions about the Defence Force Discipline Act, which is the legal structure that maintains and enforces service discipline. It covers off areas such as unrestricted service (ADF is free to deploy you wherever they need you to be), operational/combat service (all ADF personnel may be required to deploy to war zones and take part in combat), drug and alcohol policy (zero tolerance for drug/alcohol abuse), initial minimum period of service etc.
I'm not sure if it's covered by the DFDA, but they could ask you about tattoo policy, service allowances and pay, leave entitlements, rental assistance etc. as well.
Might not have covered everything but hopefully that points you in the right direction.
