How to withdraw money abroad after emigrating to Australia?

Immigrating to Australia? Then you will earn money there in the future. Do I still need to bring RMB when I go abroad? If you study there, you can bring money. If you are brave enough, you can just put the money in the box. My friend can put down 40W at most once. I usually put my money in ladies' stockings and tie it to me every time I go back to China. The money I tied at one time is about 20W. Premise: first go to the bank to find a friend to change new money. The volume gap between 20W old banknotes and new banknotes is still very large!
