I also studied a Bachelor of Agricultural Business Management through CSU - and also via distance. I found the course really suited me. I was a mature aged student (not entering uni until 23) and studying part-time whilst working full-time.
In answering your question, studying by long distance is not for the faint hearted!
I often say you have all the work of uni and none of the fun! :)
You certainly have access to all the resources of internal face-to-face students, and interaction with online forums and residential schools for most subjects, but you need to be very self motivated and driven. I enjoyed it because it fitted around my life, and I was driven by the end goal.
