<human>: Can you succinctly summarize the text in 1-3 sentences?

In Australia, all citizens get part of their course tuition paid for by the government and the rest is covered by the student, known as the voluntary contribution [I for example have pay about 2.5K per year as a full time Biomed student with the rest being covered by the government], however if we wish we can defer this payment, which means the government will also pay the 2.5K I owe and it creates a interest-free loan (it is indexed however) which I can pay back on my own accord or have it taken out of my wages with tax when I'm earning 47+ per year. Also the voluntary contribution differs depending on the field in which you're studying and you get upto a 10% discount for paying before certain dates. My question is, do you think this is a good system and how does it differ from the system you have in place in your own country?
