sounds like fun
i dont wana sound like a Defence Force recruter here, but you can all do all of this at AFDA... your courses aare paid for (no HECS), you get paid a ton of money for studying there, and when you finish, your garinteed a job in your desired field!!
job security is garinteed aswell, you can stay for 6 years in the forces, and leave on a full pension (you can also stay for more then 6 years if you want to re-sign)
once you do leave, however, you can get a job in ANY civilian company, because your training in the forces is internationally recognised, and people with millitary experience is highly regarded on your resume...
i dnt know about you, but it sounds freaking exelent to me
