Hey Anamika,
The question you are asking is a highly subjective one. The minimum tuition fee depends on which course you opt for. An example of that being the fees for a Medical course and the fees for other masters courses vary greatly. The average tuition fees that you shall be expected to pay for is between 20,000 AUD to 36,000 AUD. While the tuition fees courses such as Medicine can range between 33,000 AUD to 43,000 AUD. Maybe if you could specify the course that you are interested in, we could help you further.
