Remittance to domestic banks costs less, depending on which bank your sister uses in Australia. As long as her bank belongs to the cooperative bank of Bank of China, there is no need to charge a lot of fees. Based on 25,000 Australian dollars, she will only charge about 200 RMB. After the money is deducted from the Australian bank account, it will arrive in about 2 or 3 days. When you arrive at China Bank, you can go directly to the foreign exchange consultation.
Using other remittance methods is expensive, so it is recommended to use this method. As long as you know the BSB number, account holder's name, account holder's address, account holder's address and contact number of the other bank. Very convenient.
