Hello Jimit,
The website you posted, http://www.ici.net.au/, looks good to me. I believe it is legitimate and true to what it's saying. It is part of a network of affiliated colleges established in 1978 which together educate tens of thousands of students yearly worldwide.
If ever you will apply (or have applied) to online schools, which is sort of the "in" thing now, do visit http://www.onlinecollegeclasses.com/. It has tons of INFORMATION there (as in TONS!). Find lectures in audio/video format from famous professors of universities like Yale, etc. You could even find topnotch distance-learning schools there.
Best regards,
Iris
