In fact, there are many foreign exchange companies in Australia, and the exchange rate is better and faster than that of banks. For example, Anyan, Western Union and so on. If you are in Melbourne, go to boxhill or CIty. There are many such exchanges. You can compare exchange rates.
As long as you provide the payee's name, bank, bank and account number. In fact, there is no problem in terms of security. If you put money into their account, they will transfer it from their domestic account to your designated account, which is the most convenient. Anyway, my friends and I usually go this way, and the exchange rate is much better than that of banks. They just create differences between the two sides. If you are not at ease, you can remit money as little as possible, or go to the bank. But to be honest, I've seen people change millions of Australian dollars, and it's all right. It depends on the individual. See if you can rest assured. These money exchange companies can be found directly, which is very simple.
As for other methods, such as postal remittance, it is really not recommended. . . . Except for the company business.
