dont listen to melbournian, he's a jerk.
I do vet science, and i'm in a HECS place, but two of my close friends are on fee paying places. One of them has rich parents (ahh, wouldnt it be nice!) and the other got a student loan from the university for her first years worth of fees (ie $28,000). But her problem is that she cant get another loan at the end of the year, and she only has 5 years to pay off the student loan, and she will still be at uni, so she is trying really hard to transfer to a HECS place.
The problem there is that very very few ppl can make that switch, a HECS place only becomes available if someone else drops out, so if no one in our year drops out, none of the fee payers can transfer to a HECS place, and even if a place does become available, there are 30ish very competitive fee paying vet students all vying for that one place. So i dunno what she is going to do.
There are fee paying scholarships offerred by the vet faculty to help out, but they are only $2000 or so, and are based on financial need.
I would suggest doing a year of another course and transferring like i did, because that one extra year of study could save you $150,000. (or $110,000 if you count HECs)
