1. The Australian dollar has appreciated a lot recently. If it falls to the exchange rate you think is appropriate, you can buy it and deposit it in the bank. Of course, you can wait until you apply for studying abroad, and then you can buy it again. The exchange rate trend is a very profound and professional problem, and the top financial economists in the world are bound to make mistakes, so no one can say for sure, so they can only judge for themselves.

2. If you want to buy it, I suggest going to China Bank. It's easy to buy at the foreign exchange rate of the day. Fill in the study abroad fee for the reason of purchase.

3. Interest also changes with the adjustment of interest rate at any time. The interest rate of RMB is very low, and the interest rate of foreign currency is high.

4. No matter whether you deposit RMB and then exchange it for remittance, or exchange it with the deposit bank and then remit it now, there is no inconvenience.

I'm not a professional, but my children have done this kind of thing many times when they are studying abroad, which is a bit of experience.
