Take note of the above post. All too often I see people on forums posting sms style or failing to utilise proper English skills wanting to join the military. If you want a career in any kind of military position, start by fixing up the way you communicate with others. Also, as aaazov has said, don't attempt to join ADFA because of the "benefits", those are great, but you may find yourself in a position you do not want to be in, there are standards and codes that you may find very uncomfortable to adhere to.
As an officer you will be in charge of many people, and these are strong-willed people, especially so if many of them (and a lot will be) have served as regular army soldiers in various corps, you need to be confident that this is a challenge you can face up to, and that you wish to do it, or you will be in a world of hurt very soon.
