Help my education as I was scammed and lost 12000 Aud

Hi, my name is Riddhima and I am an international student in University of Melbourne but I was scammed in my summer break and all the money that I had saved to pay for my tuition, expenses and grocery was taken away which was more than 12000 aud. This was my dream university and I worked so hard to get into it. I am left with nothing. I am just 18 and this is a life and death situation for me. My parents have said that they won't support me anymore and that I will have to quit my degree. I might have to leave everything behind if I don't get the money. Please help me out. Think of me as your child. My education depends on this.
