Definitely RMIT , to be honest the best 3 universities in Melbourne are Melb Uni , Monash Uni and RMIT . Of course Monash and Melbourne are the most famous ones across asia , however, if for some reasons you don't want to get into these 2 , then I would strongly recommand RMIT , esp you are interested in finance and management subjects. RMIT also has reputable finance master courses which could be another factor that you want to consider when you make the decision. For updated information about course fee , you can easily find it from
www.rmit.edu.au and
www.mibt.edu.au .
You would be expecting the amount like around $17000 to $20000 AUD per year.
